Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] The "Environment-1" (HJ-1A / B) satellite system is an earth observation system approved by the State Council of China for environmental and disaster monitoring. All-day, dynamic environment and disaster monitoring capabilities. HJ-1A / B star data can not only provide an important guarantee for the environment and disaster reduction business operation system, but also become an important data source for the daily business of many departments. The environment and disaster reduction application system based on environmental satellite data has an important demonstration role in promoting remote sensing satellite business services. The observation satellite mentioned in ...

Abstract

The invention provides a non-point source pollution calculation method based on a remotely sensed image element. The method comprises the following steps of: 1, constructing a land utilization database and a vegetation coverage database; 2, constructing a soil type database, a soil nitrogen and phosphorus attribute database and a gradient and slope length geographic space database; 3, constructing a farmland nitrogen and phosphorus balance amount space database; 4, calculating dissolved state non-point source loads and adsorption type non-point source loads of non-point source pollutants under different pollution types according to database information in the steps from 1 to 3 and the pollution types; and 5, calculating a total amount of non-point source pollutants in a river according to the dissolved state non-point source loads and the adsorption type non-point source loads. By the method, under the condition that a data condition is limited, a non-point source pollution space distribution feature and a source intensity feature can be quickly obtained based on remotely sensed data; effective pollution monitoring measures can be supplied to a pollution prevention, treatment and management department; and important technology support can be supplied to flow domain pollution management.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a calculation method for non-point source pollution, in particular to a calculation method for non-point source pollution based on remote sensing pixels. Background technique [0002] At present, under the background of effective control of industrial point sources in my country, the situation of agricultural non-point source pollution is becoming more and more serious. Vice Premier Li Keqiang pointed out at the symposium on the application of China's environmental macro strategy research results: rural non-point source pollution has become an important factor affecting the water environment, and nearly half of the country's chemical oxygen demand comes from agricultural pollution sources. Therefore, developing a non-point source pollution estimation model suitable for my country's national conditions is an urgent task for my country's pollution management and co...
