-
In order to effectively ensure the safety of Fuxianhu Lake Basin ecological environment and promote its sustainable development, the situation of soil erosion of Fuxianhu Lake Basin was studied by means of remote sensing monitoring. The soil erosion amount of Fuxianhu Lake Basin during the period from 1974 to 2014 was estimated by using method of combination of 3S technology and field investigation and based on achievements of general survey of the first national geographical conditions in Yunnan Province and USLE model, and the spatiotemporal distribution and change rule of soil erosion intensity in this basin were discussed. The results showed that: (1) the soil erosion intensity in Fuxianhu Lake Basin was greatly influenced by rainfall; (2) the amount of soil erosion presented a trend of fluctuation increase, decline and then rise, and different intensities of soil erosion changes showed that the soil erosion had experienced the changing processes of initial intensification and later slightness, soil erosion degree was intensifying in some sensitive area of in the basin; (3) the spatial distribution of soil erosion in the basin had the consistency, the most serious soil erosion area of the basin distributed on both sides of the East and West, and parts of the south region.
