Abstract

The invention discloses a source / sink landscape recognition method and apparatus of non-point source pollution. The method includes steps of determining resistance coefficients and dynamic coefficients of a current landscape unit and related landscape units thereof by employing resistance coefficients and dynamic coefficients of the current landscape unit and the related landscape units influencing a non-point source pollution process; calculating the resistance cost and the power cost of the current landscape unit by employing the resistance coefficients and the dynamic coefficients of the current landscape unit and the related landscape units thereof and the distances from the current landscape unit and the related landscape units thereof to sub-basin water outlets; and recognizing source / sink landscapes of the non-point source pollution according to the resistance cost and the power cost of the current landscape unit. According to the method and apparatus, the dynamic process of the formation of non-point source pollution from the landscape units to the sub-basin water outlets can be recognized and monitored, and an important significance is attached to further deep revealing of the coupling relationship between large-scale landscape patterns and the ecological process.

Description

Technical field [0001] The invention relates to a method and device for identifying the source / sink landscape of non-point source pollution. Background technique [0002] The process of non-point source pollution is affected by the local climate, hydrology, topography, land use, soil and vegetation cover and other influencing factors, so that there are obvious spatial differences in the area of ​​non-point source pollution, so it is difficult to monitor and prevent non-point source pollution. Impact on the water environment. [0003] Therefore, how to identify and monitor the occurrence and development of non-point source pollution in an area from a better and more comprehensive perspective has certain practical significance. Summary of the invention [0004] The purpose of the present invention is to provide a method and device for identifying the source / sink landscape of non-point source pollution, which can better solve the problem of recognition and monitoring of non-point sour...
