- Abstract:
-
Digital Elevation Mode (DEM) was made based on topographic map of the study area, slope and aspect were computed according to DEM. The information of special topic on soil and water conservation was collected, by overlapping the special information of the land use type, intensity of soil erosion and seawater quality of Fuxian Lake (transparency, TN, TP, on average) in order to determine the relationship of the different types of land-use, terrain factors, the soil erosion types and corrosion process. Analysis on the application of the collected data was carried out and conduct applied on. The results showed that water quality in Fuxian Lake related to the land-use, and soil erosion patterns showed distinct vertical zonality in Fuxian Lake basin, soil erosion intensity was affected by the soil type and vegetation coverage condition. Different aspects of slopes made erosion intensity diverse obviously, and different ranges of slope led to diversity in the main soil erosion types.
