Description
Technical field
Patent of the present invention relates to a kind of carbon emission metering method, relates in particular to a kind of carbon emission metering method based on city planning, belongs to low-carbon technology field.
Background technology
In United Nations Framework Convention on Climate Change, climate change refers to and " through the observation of quite a while, changes directly or indirectly global atmosphere form caused climate change outside natural climate changes by mankind's activity." the up-to-date successes achieved in research show: global earth's surface medial temperature in the last hundred years (1906-2005) has raise 0.74 DEG C, expects 21 century end will rise 1.1-6.4 DEG C.United Nations Environment Programme (UNEP) (UNEP) Days report March 16 in 2008: due to Global climate change, melt with the fastest speed in glacier, and many glaciers may disappear in many decades.IPCC(2007) investigation is found: 0.3m shrinks back every year on average between 1980-1999 in nearly 30 glaciers all over the world; But from 2000, astern speed rose to every annual 0.37m; The 2006 annuals 1.5m that shunk back.The Nature magazine report of publishing on June 19th, 2008 utilizes the view mode having improved with comparison climate model from the research group at U.S. Lao Lunsi livermore national laboratory, Australian weather and weather center and antarctic climate and ecosystem joint study center, result shows, between 1961 to 2003, the annual ascending velocity in sea level is 1.5mm, between these 42 years, sea level rise about 6.35cm.Global climate change will cause the crisis of earth natural ecosystems, and cause huge disaster to human society!
The impact of climate change on natural ecosystems, the variable effect of global climate system is to water globe thermal cycle general layout, cause the meteorological disasters such as flood, arid and hurricane frequently to occur, also destroy earth surface state, cause the deterioration of the ecological environment, simultaneously the ecosystem feeds back again variation, causes more frequently or stronger abrupt change of climate and the generation of gradually changeable disaster event, or owing to cannot adapting to change, and cause the heavy losses of bio-diversity in the ecosystem.Regional climate changes particularly temperature rising and many natural systems has been produced to impact.According to prediction, the impact of even more serious climate change will be suffered to nature in 2100.Current undeveloped forest will have a lot of degenerations or disappearance, the hot zones that also has most of bio-diversities disappearing together in company with them.Along with the disappearance of these ecosystems, on the earth, half or animals and plants species over half will disappear.
Climate change, in affecting natural ecosystems, also can produce deep effect to agricultural production, and climate change affects the speed of growth, the quality and yield of crops by affecting photosynthesis, the transpiration etc. of crops; The rising of CO2 concentration can produce that weeds prosperity, disease and pest increase the weight of, agricultural chemicals and the spinoff such as effect of fertilizer weakens, arid intensifies, soil depletion; In the situation that CO2 concentration raises, the C of Crop increases, N reduces, and in body, C/N is than raising, and protein content will reduce, thereby crop quality is declined.On produce and the impact of living environment also very large, due to global warming, the human settlement in mountain area is strengthened by the burst risk of flood of glade that glacial ablation causes; Sea-level rise causes the human habitat of coastland more severe, and the rising on sea level and mankind's activity all can cause coastal wetland to disappear; Development of Urbanization fast Area Inhabitants will face larger climate change risk because they produce and the adaptive faculty of living system limited, climate change is shown to stronger fragility, also stronger to the dependence of climate resources.
Under the impact of Britain's " low-carbon economy ", mostly scholar defines low-carbon (LC) city-emphasize " low energy consumption, low pollution, low emission and high-effect, high-level efficiency, high benefit " from low-carbon economy angle, taking low-carbon (LC) as developing direction, taking energy-saving and emission-reduction as development pattern, taking in carbon and technology as the urban development pattern of development method, and low-carbon (LC) city is from economic angle, low-carbon (LC) theory to be explained, a little less than paying close attention to other aspects such as city space, culture.Based on the current demand of urban ecology development, low carbon development, low-carbon ecological city is taken the lead in proposing by Chou Baoxing, quietly occurs and develops rapidly on Chinese territory.Three kind classes of cities-low-carbon (LC) city, low-carbon ecological city and the ecocities higher as the current degree of recognition of China easily produce the puzzlement that is difficult to differentiation each other.Shen Qingji, from philosophy, function, economy, four aspects in space and social context, distinguishes low-carbon (LC) city, ecocity and low-carbon (LC) city.Low-carbon (LC) city is as solving the current sixty-four dollar question-carbon emission in city, with clearly defined objective, in the primary stage of Eco-City Development, and relatively more acceptant and realization.And from implementing angle, the connotation and extension of " low-carbon (LC) " concept has comprised many-sided concrete practice content such as " low-carbon (LC) production ", " low-carbon (LC) life ", make to there is solid foundation in " low-carbon (LC) city " " low-carbon (LC) " system under a large motion of society and ideological trend background, the content of implementing also more extensively, specifically, final urban construction target just more easily reaches, and along with the foundation in carbon market in world wide, the trend that the enforcement of Clean Development Mechanism and climate change grow in intensity has more been strengthened the urgency of low-carbon (LC) research.Therefore using " low-carbon (LC) city " as desirable city pattern in the present age, all more superior aspect ideological plane and real operation.Fu Yun etc. (2010) are 5 aspects by the feature overview in low-carbon (LC) city: economy, security, systematicness, dynamic, regionality.
China Urban Studies Society (2009) thinks, low-carbon (LC) urban characteristic comprises the low carbonization industrial structure, hyperbaric energy saving building, low carbonization public transportation system, low carbonization energy system, power-saving technology and high greening level.Julia K.Steinberger, Helga Weisz(2009) by using urban energy to use the method for classification, every factor in analyzing influence low-carbon (LC) city and the variation tendency causing, the factor that affects low-carbon (LC) city is divided into three yardsticks to be described: micro-scale, and electrical equipment and motor vehicle are two of most critical wherein; Middle sight yardstick, building, process of industrialization, mode of transportation are wherein representative three aspects :s; Macro-scale, city density, land use diversity and transportation network have determined the city carbon emission effect in this stage.Ichinose(2009) key issue in proposition low-carbon (LC) city is: countermeasure-room conditioning power-saving technology, the life style etc. of public transportation system, thermal comfort.Pan Haixiao (2008) thinks that the technological means of the adjustment of guiding urban industrial structure, the development that promotes recycling economy, application of advanced and strict environmental protection are the Critical policies of realizing " low-carbon (LC) city ".Chen Fei etc. (2009) think should be in building, traffic, the large field development of production three low-carbon (LC) pattern, make full use of regenerative resource, strengthen forest, marsh, wetlands ecosystems scale, and propose the thinking that breaks off relations and develop, economic growth is combined with low carbon development.Chen Qunyuan (2009) proposes the planning concept in China's low-carbon (LC) city: reduce energy resource consumption by planning means.I.e. control high-carbon industry development aspect Urumqi, industrial development planning; Aspect traffic programme, implement the travel pattern of taking as the leading factor with public transport, control private traffic trip quantity; Aspect architectural design, replace traditional architecture with green building.By planning means Optimization of Energy Structure, it is mainly the programme that adopts green energy resource, clean technologies.Strengthen city carbon sink by planning means, by soil utilization adjustment, greenhouse gases are stored in to biological carbon storehouse, and improve greening function, the suction carbon function of city unit green area area, improve the carbon sink in city.Some requirement of the low-carbon ecological city planning that Chou Baoxing (2009) proposes is also applicable to low-carbon (LC) city, comprises in environment and carbon emission problem, and the renewable energy system of innovating by employing, cover town scope, realizes comprehensive low-carbon emission control.On traffic problems, will improve walking, bicycle and use share of public transportation as city overall development target.On residence problem, carry out real-time energy source monitoring system in architectural design and construction, disposed chamber according to 65% above building energy-saving standard.In the problem of employment, urban inner is realized commercial affairs and the inhabitation function of mixing, and reduces the commuter of pendulum model.On service facility, build continuable community, reduce this type of trip requirements.On green infrastructure, green space is not less than 40%, and wherein has at least 50% to be public, well-regulated, high-quality green opening space network.On water resources problems, aspect water saving, need possess long-range and actual effect target, especially in the area of those serious water shortages.In offal treatment problem, degree for the treatment of and the recovery levels of municipal garbage reach 100%; Consider this area junk to become and give up as energy, obtain heat energy and electric energy.
The low-carbon (LC) urban planning theory of China put forward since 2008, was the planing method of the application in city planning based on low-carbon (LC) theory.The Pan Haixiao of Tongji University professor article " China " low-carbon (LC) city " empty planning strategy ", from the angle of city planning, " low-carbon (LC) city " concept is proposed for the first time, in its article " towards the city's spatial structure of low-carbon (LC)---the new model of urban transportation and land use " and " traffic in low-carbon (LC) city and land use pattern ", mention low-carbon (LC) city and low-carbon (LC) city planning, and carried out more deep research based on traffic or urban structure aspect, its achievement in research is having good reference aspect low-carbon (LC) city; On July 12nd, 2009, speech " China urban development pattern transition trend-low-carbon ecological city " literary composition of the vice-minister Chou Baoxing of house town and country construction portion on city and development plan international symposium, has proposed the idea that low-carbon (LC) city and low-carbon (LC) are planned; 2050 Chinese energy and carbon emission seminar, in its achievement in research " 2050 Chinese energy and carbon emission report ", propose to build the necessity and urgency in low-carbon (LC) city.
