Wherein the multispectral 102 is in communication with the server 104. The communication mode may be any mode such as wired or wireless. In order to collect the water and soil conservation condition of the construction site, before collecting the multispectral information of the construction site through the multispectral instrument 102, the multispectral instrument 102 needs to be carried on the flight device, and the flight device flies according to a preset flight track, so that aerial photography of the construction site can be realized to collect the multispectral information of the construction site. The construction site is a construction land which is under construction or is constructed within a preset time period. The construction site comprises soil, vegetation and a green net (a green net cover for construction), the soil with different soil qualities, the vegetation with different colors and the green net with confusion, and the construction site respectively has corresponding multispectral information. The multispectral information of the construction site refers to multispectral information including soil, vegetation, green nets and the like. In order to monitor the construction disturbance conditions of the construction site in different time periods, the multispectral information of the construction site collected in each time period is compared with the multispectral information of the construction site collected in the previous time period respectively, so that the multispectral information change condition of the construction site corresponding to each current time period is obtained, the disturbance condition of the construction corresponding to each current time period on water and soil can be known based on the multispectral information change condition, and the water and soil disturbance condition in the construction process can be mastered in time through multi-time period tight analysis and continuous tracking. The key construction part is a construction part with the probability of water and soil flowing water higher than a threshold value in the construction process of a construction site. The method for collecting multispectral information of key construction parts is the same as the method for collecting and comparing construction sites, and the method is not repeated.

After the construction is finished, the multispectral information needs to be collected on the construction site and key construction parts again, and compared with the water and soil disturbance condition before the construction, so that the water and soil disturbance condition of the whole construction after the construction is finished can be determined.
In one embodiment, when initial multispectral information before construction of a construction site is acquired, a server sends a flight instruction and a preset flight track to flight equipment, the flight equipment receives and responds to the flight instruction, carries a multispectral instrument to fly according to the preset flight track, and the multispectral information before construction of the construction site is acquired through the multispectral instrument.

In one embodiment, when the final multispectral information after construction of the construction site is obtained, the server sends a flight instruction and a preset flight track to the flight equipment, the flight equipment receives and responds to the flight instruction, carries the multispectral instrument to fly according to the preset flight track, and obtains the final multispectral information after construction of the construction site through the multispectral instrument; the multi-spectrometer sends the constructed final multi-spectral information to a server; and the server receives the constructed final multispectral information.

And constructing the sites with different acquisition times. And comparing the multispectral information of the construction site at different acquisition times to obtain a first analysis result, wherein the first analysis result is the water and soil disturbance condition corresponding to each acquisition time in the construction process of the construction site and after the construction is finished.

The standard spectral information of each water and soil element refers to a standard value of the spectral information of each element. When acquiring multispectral information of a construction site acquired by a plurality of spectrometers, comparing the multispectral information according to standard spectral information, and further determining land types contained in the construction site, wherein the land types represent vegetation conditions of soil. Such as composite fields, generally refer to fields that include disordered vegetation, such as trees, shrubs, turf, and flowering plants.

For example, when the preset collection frequency is once every quarter and the construction period is six months, the construction time period in the construction process is two. The preset acquisition frequency in the construction process is preset in the server, the preset acquisition frequency can be set according to the expected construction period, and the longer the expected construction period is, the smaller the preset acquisition frequency is; the shorter the construction period is expected to be, the larger the preset acquisition frequency is. For example, the construction period is six months, and the preset collection frequency can be once a month; when the construction period is two months, the preset acquisition frequency can be once every two weeks. When the whole construction process is finished and continuous extreme weather does not exist, the preset acquisition frequency comprises once every quarter. When continuous extreme weather occurs during construction, the preset collection frequency can be set to be once a month. According to the preset acquisition frequency, the flight equipment carries a plurality of spectrometers to monitor the construction site and the key construction parts.
In the embodiment, the construction time period in the construction process is determined through the preset acquisition frequency, so that the construction site and key construction parts can be monitored more regularly.
In one embodiment, extreme weather includes: and (4) heavy rainfall weather with rainfall greater than a preset value.
The preset value is preset and used for judging the rainfall intensity condition. The rainfall is larger than the preset value, which indicates the weather is heavy rainfall. The rainfall is not less than the preset value, namely, the rainfall is not strong rainfall weather. Heavy rainfall weather is one of the extreme weather, which also includes continuous rainfall, and weather that is continuous rainfall and is heavy rainfall.
In this embodiment, when extreme weather time such as heavy rainfall takes place, monitor the soil and water disturbance condition of construction place and key construction position to can in time deal with the influence that extreme weather may be to the soil and water disturbance.
In one embodiment, if the disturbance condition of the construction on the water and soil obtained after the construction is finished cannot be checked through the water and soil maintenance, the multi-spectrometer is instructed to perform multi-spectral information on the construction site again within the preset time after the construction is finished; comparing the multispectral information of the construction site collected again after construction with the multispectral information collected for the first time; and evaluating whether the water and soil conservation acceptance is passed or not according to the comparison result.
When receiving the multispectral information sent by each acquisition time, the server compares the multispectral information with the standard spectral information to determine each land and the area of each land.
And the water and soil conservation acceptance means that the water and soil of the construction site are kept in accordance with national, local or industrial standards. And the water and soil conservation acceptance comprises the minimum area occupied by all land types of the construction site. After construction is completed, whether the water and soil disturbance condition of the construction site can be checked and accepted through water and soil conservation is checked, and when the water and soil disturbance condition of the construction site can be accepted through water and soil conservation, the construction site is only required to be subjected to multispectral information collection once after construction is completed. When the water and soil disturbance condition of the construction site cannot be accepted through water and soil conservation, the construction site needs to be subjected to at least one more multispectral information acquisition after the construction is completed. And comparing the multispectral information of the construction site collected again after the construction is finished with the multispectral information collected for the first time after the construction is finished. And evaluating whether the water and soil conservation acceptance can be passed or not according to the comparison result. And when the comparison result is that the multispectral information collected again is compared with the multispectral information collected for the first time, and the determined area of each place meets the minimum area requirement of water and soil conservation acceptance check, determining that the construction of the current construction site passes the water and soil conservation acceptance check. The reason why the multispectral information of the construction site collected again can be checked and accepted through water and soil is that after construction is finished and after the multispectral information collected for the first time, vegetation newly planted in the construction site grows to a certain degree or the construction site is partially or completely recovered.
In the embodiment, after the construction is finished, after the multispectral information is collected for the first time, the multispectral information of the construction site is collected again, whether the multispectral information can pass through water and soil conservation acceptance is evaluated according to the comparison result of the multispectral information and the water and soil conservation acceptance, and the vegetation needs time to grow or recover is fully considered, so that the collected multispectral information is closer to the real water and soil disturbance condition after the construction is finished.
