（実施例１）
本実施例を具体的に説明する前に、基礎となった知見を説明する。自然災害時には、家屋建築物の倒壊や被災家屋からの被災家財等、大量の災害廃棄物が生じる。この災害廃棄物については、２０１１年東日本大震災の経験から、２０１３年に南海トラフ地震対策特別措置法および国土強靭化基本法が成立している。また、内閣官房に設置された国土強靭化推進本部が中心となり、国土強靭化大綱が公表され、災害廃棄物対策が巨大災害時の重要な施策として位置付けられている。環境省においても、南海トラフ地震等による災害廃棄物の発生量の推計や既存の廃棄物処理施設における処理可能量の試算等の検討を踏まえ、巨大災害への対応を考慮した総合的な災害廃棄物対策の基本的な方向について、グランドデザインとして取り纏めている。そこでは、１）膨大な災害廃棄物の円滑な処理の確保、２）東日本大震災の教訓を踏まえた発災前の周到な事前準備と発災後の迅速な対応、３）衛生状態の悪化、環境汚染の最小化による国民の健康の維持、４）強靭な廃棄物処理システムの確保と資源循環への貢献、５）大規模広域災害を念頭に置いたバックアップ機能の確保、という５つの事項について、大規模災害の発生に向けた対策のあるべき方向が示されている。
Example 1
Prior to specific description of the present embodiment, the basic knowledge will be described. During a natural disaster, a large amount of disaster waste is generated, such as collapse of a house building or a damaged house property from a damaged house. As for this disaster waste, the Nankai Trough Earthquake Special Measures Law and the National Land Toughening Basic Law were enacted in 2013 based on the experience of the 2011 Great East Japan Earthquake. In addition, the National Land Resilience Promotion Headquarters established in the Cabinet Secretariat is the center, and the National Land Resilience Charter has been published, and disaster waste management is positioned as an important measure in the event of a major disaster. The Ministry of the Environment will also conduct comprehensive disaster disposal considering the response to major disasters based on the estimation of the amount of disaster waste generated due to the Nankai Trough Earthquake and the like, and the estimation of the amount that can be processed at existing waste disposal facilities. The basic direction of physical measures is summarized as a grand design. 1) Ensuring smooth disposal of enormous disaster waste 2) Thorough pre-preparation and quick response after the disaster based on lessons learned from the Great East Japan Earthquake 3) Deterioration of sanitation, environment Concerning five matters: maintaining public health by minimizing pollution, 4) securing a robust waste disposal system and contributing to resource recycling, and 5) securing a backup function with large-scale wide-area disasters in mind. The direction that should be taken for the occurrence of large-scale disasters is shown.
基礎自治体においては、将来の災害に備えた災害廃棄物処理計画の策定、あるいは発災後に速やかに災害廃棄物処理の実行計画策定に資する簡便かつ精度よく災害廃棄物の要処理量を把握する手法が求められている。これによって、廃棄物部局が、災害後にできる限り迅速に処理すべき災害廃棄物量を把握できる。その結果、廃棄物部局が、受援を含めた災害廃棄物対応の体制構築、仮置場の確保、中間処理、最終処分や再生利用等の災害廃棄物処理フローの構築、広域連携や広域処理に向けた調整等の災害対応業務を的確に遂行することができ、被災地域での生活環境の保全および公衆衛生の向上が可能となる。一方、熊本県熊本地方で２０１６年４月に発生した地震では、被害報における住家被害の情報が時々刻々と変動したり、被害情報の精度や集計手法により大きく変動したり、住家被害の把握に時間を要して情報が更新されなかったりした。したがって、被害報における住家被害棟数から発災後に速やかに災害廃棄物量を把握することが困難であったといえる。 In the basic local government, a method for easily and accurately grasping the amount of disaster waste to be processed that contributes to the formulation of a disaster waste treatment plan for future disasters, or the creation of an execution plan for disaster waste treatment as soon as the disaster occurs Is required. As a result, the waste department can grasp the amount of disaster waste to be processed as quickly as possible after a disaster. As a result, the waste bureau will establish a system for handling disaster waste including support, secure temporary storage, construction of disaster waste processing flows such as intermediate processing, final disposal and recycling, wide area cooperation and wide area processing. It is possible to accurately carry out disaster response operations such as adjustments aimed at, and it is possible to preserve the living environment and improve public health in the affected areas. On the other hand, in the earthquake that occurred in April 2016 in the Kumamoto region of Kumamoto Prefecture, the information on the damage to houses in the damage report fluctuates from time to time, or changes greatly depending on the accuracy of the damage information and the aggregation method, and it is used to understand damage to houses. The information was not updated over time. Therefore, it can be said that it was difficult to grasp the amount of disaster waste immediately after the disaster based on the number of houses damaged in the damage report.
これまでは、個別の住宅情報を行政が管理しているが、個人情報保護法により利用範囲が限定されている。このような一般に入手不可能な情報を用いて、高精度に推定する手法が検討されてきている。また、災害発生後に取得可能な衛星画像や航空写真と住宅境界データ等を用いて、住宅棟数を把握する技術などが開発されてきている。さらに、都道府県別や市町村別に集計された被害情報における住家被害の棟数に災害廃棄物量原単位を乗じて算出する技術、あるいは、個人情報保護法により使用範囲が限定されている固定資産台帳等の情報から、被災面積を算出し、被災面積当たりの災害廃棄物量を用いて算出する技術などがある。しかしながら、これによっても、一般に入手可能な情報をもとに、災害発生後、速やかに災害の影響を把握することは困難である。そのため、本実施例では、メッシュ法による災害廃棄物量の推定手法を用いて、広く一般に入手可能なセンサスデータと災害直後に入手できる災害情報より、災害初動時において、災害の影響、例えば災害廃棄物量を把握することを目的とする。 Until now, the administration of individual housing information has been managed, but the range of use is limited by the Personal Information Protection Law. Techniques for estimating with high accuracy using such information that is generally unavailable have been studied. In addition, a technique for grasping the number of houses by using satellite images, aerial photographs and house boundary data that can be acquired after a disaster has been developed. In addition, a technology that calculates the number of houses damaged in the damage information aggregated by prefecture or city / village by multiplying the basic unit of disaster waste, or a fixed asset ledger whose scope of use is limited by the Personal Information Protection Law, etc. For example, there is a technique for calculating the disaster area from the information and using the amount of disaster waste per disaster area. However, even in this case, it is difficult to quickly grasp the impact of a disaster after the occurrence of a disaster based on generally available information. For this reason, in this example, using the method of estimating the amount of disaster waste by the mesh method, the impact of the disaster, for example, the amount of disaster waste, at the time of the initial disaster, based on the widely available census data and the disaster information available immediately after the disaster. The purpose is to grasp.
図１は、本実施例１に係る処理装置１００の構成を示す。処理装置１００は、データベース８０、第１取得部２０、第２取得部２２、第３取得部２４、第４取得部２６、第５取得部２８、処理部３０、表示部６０を含む。データベース８０は、第１データベース１０、第２データベース１２、第３データベース１４、第４データベース１６、第５データベース１８を含む。処理部３０は、第１導出部４０、第２導出部４２、第３導出部４４、第４導出部４６、第５導出部４８、第６導出部５０、第７導出部５２を含む。 FIG. 1 illustrates a configuration of a processing apparatus 100 according to the first embodiment. The processing device 100 includes a database 80, a first acquisition unit 20, a second acquisition unit 22, a third acquisition unit 24, a fourth acquisition unit 26, a fifth acquisition unit 28, a processing unit 30, and a display unit 60. The database 80 includes a first database 10, a second database 12, a third database 14, a fourth database 16, and a fifth database 18. The processing unit 30 includes a first derivation unit 40, a second derivation unit 42, a third derivation unit 44, a fourth derivation unit 46, a fifth derivation unit 48, a sixth derivation unit 50, and a seventh derivation unit 52.
第１データベース１０は、センサスデータとして国勢調査に関する地域メッシュ統計を記憶する。総務省統計局の地域メッシュ統計では、２分の１地域メッシュの各メッシュに対する世帯総数と共同住宅世帯数が示される。地域メッシュは、統計に利用するために、緯度・経度に基づいて地域をほぼ同じ大きさのメッシュに分けたものである。例えば、基準地域メッシュでは、各メッシュの緯度差が３０秒、経度差が４５秒にされるので、各メッシュの１辺の長さは約１ｋｍである。また、２分の１地域メッシュは、基準地域メッシュを縦横に２等分したものであり、緯度差が１５秒、経度差が２２．５秒にされるので、各メッシュの１辺の長さは約５００ｍである。第１取得部２０は、第１データベース１０から、２分の１地域メッシュ単位の世帯総数と、２分の１地域メッシュ単位の共同住宅世帯数とを取得する。 The first database 10 stores regional mesh statistics related to the national census as census data. The regional mesh statistics of the Statistics Bureau of the Ministry of Internal Affairs and Communications indicate the total number of households and the number of apartment housing households for each mesh of the half regional mesh. The region mesh is obtained by dividing a region into meshes of almost the same size based on latitude and longitude for use in statistics. For example, in the reference area mesh, the latitude difference of each mesh is set to 30 seconds and the longitude difference is set to 45 seconds. Therefore, the length of one side of each mesh is about 1 km. In addition, the half area mesh is obtained by dividing the reference area mesh into two equal parts vertically and horizontally, and the latitude difference is 15 seconds and the longitude difference is 22.5 seconds. Is about 500 m. The first acquisition unit 20 acquires the total number of households in half-area mesh units and the number of apartment houses in half-region mesh units from the first database 10.
第１導出部４０は、第１取得部２０において取得した２分の１地域メッシュ単位の世帯総数と、２分の１地域メッシュ単位の共同住宅世帯数とをもとに、２分の１地域メッシュ単位の木造住宅割合と、２分の１地域メッシュ単位の非木造住宅割合とを導出する。
木造住宅割合＝１−共同住宅世帯数／世帯総数・・・式（１）
非木造住宅割合＝共同住宅世帯数／世帯総数・・・式（２）
The first deriving unit 40 calculates the one-half region based on the total number of households in half area mesh units acquired in the first acquiring unit 20 and the number of apartment houses in half area mesh units. The ratio of wooden houses in mesh units and the ratio of non-wooden houses in half-area mesh units are derived.
Wooden house ratio = 1-the number of apartment houses / total number of households (1)
Non-wooden house ratio = Number of apartment houses / Total number of households (2)
第２データベース１２は、センサスデータとして住宅・土地統計調査における第２表を記憶する。総務省統計局の住宅・土地統計調査では、都道府県ならびに政令指定都市別の住宅総数と世帯総数が示される。都道府県ならびに政令指定都市は、２分の１地域メッシュよりも大きな区域である。そのため、２分の１地域メッシュを第１区域と呼ぶ場合、都道府県ならびに政令指定都市は、第１区域よりも広い第２区域と呼ばれる。以下では、都道府県ならびに政令指定都市を「都道府県」と総称する。第２取得部２２は、第２データベース１２から、都道府県単位の住宅総数と、都道府県単位の世帯総数とを取得する。 The 2nd database 12 memorizes the 2nd table in a house and land statistics survey as census data. The Ministry of Internal Affairs and Communications Statistics Bureau's Housing and Land Statistics Survey shows the total number of homes and households by prefecture and designated city. Prefectures and government-designated cities are larger than a half-regional mesh. Therefore, when the half area mesh is referred to as the first area, the prefecture and the ordinance-designated city are referred to as the second area wider than the first area. Hereinafter, prefectures and designated cities are collectively referred to as “prefectures”. The second acquisition unit 22 acquires the total number of houses in each prefecture and the total number of households in each prefecture from the second database 12.
第２導出部４２は、第２取得部２２において取得した都道府県単位の住宅総数と、都道府県単位の世帯総数とをもとに、都道府県単位の世帯当たりの住宅棟数を導出する。
世帯当たりの住宅棟数＝住宅総数／世帯総数・・・式（３）
The second deriving unit 42 derives the number of houses per household for each prefecture based on the total number of houses for each prefecture acquired by the second acquisition unit 22 and the total number of households for each prefecture.
Number of residential buildings per household = total number of houses / total number of households (3)
第３導出部４４は、第２導出部４２において導出した都道府県単位の世帯当たりの住宅棟数と、第１取得部２０において取得した２分の１地域メッシュ単位の世帯総数と、第１導出部４０において導出した２分の１地域メッシュ単位の木造住宅割合とをもとに、２分の１地域メッシュ単位の木造住宅棟数を導出する。
木造住宅棟数＝世帯総数×世帯当たりの住宅棟数×木造住宅割合・・・式（４）
また、第３導出部４４は、第２導出部４２において導出した都道府県単位の世帯当たりの住宅棟数と、第１取得部２０において取得した２分の１地域メッシュ単位の世帯総数と、第１導出部４０において導出した２分の１地域メッシュ単位の非木造住宅割合とをもとに、２分の１地域メッシュ単位の非木造住宅棟数を導出する。
非木造住宅棟数＝世帯総数×世帯当たりの住宅棟数×非木造住宅割合・・・式（５）
The third deriving unit 44 calculates the number of residential buildings per household calculated in the second deriving unit 42, the total number of households in half area mesh units acquired in the first acquiring unit 20, and the first derivation. Based on the half-area mesh unit wooden house ratio derived in the section 40, the number of half-region mesh unit wooden houses is derived.
Number of wooden houses = total number of households x number of houses per household x percentage of wooden houses ... Formula (4)
In addition, the third deriving unit 44 includes the number of residential buildings per household calculated by the second deriving unit 42, the total number of households in half-area mesh units acquired by the first acquiring unit 20, Based on the ratio of non-wooden houses in half area mesh units derived in the one deriving unit 40, the number of non-wooden house buildings in half area mesh units is derived.
Number of non-wooden houses = Total number of households x Number of houses per household x Non-wooden house ratio ... Formula (5)
第３データベース１４は、センサスデータとして住宅・土地統計調査における第４表を記憶する。総務省統計局の住宅・土地統計調査では、都道府県単位の木造住宅の時期別住宅数と、都道府県単位の非木造住宅の時期別住宅数が示される。ここで、木造住宅には、木造（防火木造を除く）と防火木造が含まれ、非木造住宅には、鉄筋・鉄骨コンクリート造と鉄骨造が含まれる。図２は、第３データベース１４に記憶されるデータに対して規定される建築の時期区分を示す。建築の時期区分については、中央防災会議における住宅被害関数にしたがい、木造住宅は６区分、非木造住宅は３区分として規定される。また、図２には、住宅被害関数の建築の時期区分（木造６区分、非木造３区分）と、住宅・土地統計調査の建築の時期（１４区分）との関係も示される。図１に戻る。第３取得部２４は、第３データベース１４から、都道府県単位の木造住宅の時期別住宅数と、都道府県単位の非木造住宅の時期別住宅数とを取得する。 The 3rd database 14 memorizes the 4th table in a house and land statistics survey as census data. The Ministry of Internal Affairs and Communications Statistics Bureau's Housing and Land Statistics Survey shows the number of wooden houses by period of prefectures and the number of non-wooden houses by period of prefectures. Here, the wooden house includes a wooden structure (excluding fireproof wooden structure) and a fireproof wooden structure, and the non-wooden house includes a reinforcing steel / steel concrete structure and a steel structure. FIG. 2 shows the building time divisions defined for the data stored in the third database 14. Regarding the construction period, according to the housing damage function at the Central Disaster Prevention Council, wooden houses are defined as 6 categories and non-wooden houses as 3 categories. In addition, FIG. 2 also shows the relationship between the building time category of the housing damage function (6 wooden categories and non-wooden 3 categories) and the building time of the housing and land statistics survey (14 categories). Returning to FIG. The third acquisition unit 24 acquires, from the third database 14, the number of houses by period of wooden houses by prefecture and the number of houses by period of non-wooden houses by prefecture.
第４導出部４６は、第３取得部２４において取得した都道府県単位の木造住宅の時期別住宅数と、第２取得部２２において取得した都道府県単位の住宅総数とをもとに、都道府県単位の木造住宅の建築の時期の割合を導出する。

The distribution of the number of damaged wooden houses and the distribution of damaged non-wooden houses can be ascertained for each 1/2 area mesh. Using disaster information, regional mesh statistics on publicly available census data, and housing and land statistics surveys, the number of damaged wooden and non-wooden buildings is calculated for each half-area mesh, and disasters can be quickly completed. The distribution of waste amount can be calculated.
また、地方自治体における環境部局等、災害や建築の専門家でなくとも、災害時の災害情報を用いて住宅被害を把握できる。また、災害情報について、地域防災計画等の災害前に検討されている推定地震動等などの災害情報を使用するので、災害前に住宅被害を検討できる。また、災害後においても、数時間から２日程度で、２分の１地域メッシュ単位での災害廃棄物量の把握が可能となり、被災地域における災害廃棄物対応に活かすことができる。また、災害前であっても、全国のいかなる地域においても、想定されたさまざまな災害に対する災害廃棄物量を把握できる。 Moreover, even if it is not a disaster or construction specialist such as an environmental department in a local government, it is possible to grasp housing damage using disaster information at the time of a disaster. In addition, since disaster information such as estimated earthquake motion that has been examined before a disaster, such as a regional disaster prevention plan, is used for disaster information, it is possible to examine housing damage before a disaster. In addition, even after a disaster, it is possible to grasp the amount of disaster waste in units of one-half area mesh within a few hours to two days, and this can be utilized for dealing with disaster waste in the affected area. Moreover, even before a disaster, it is possible to grasp the amount of disaster waste for various assumed disasters in any region of the country.
