Based on an analysis of three phases of remote sensing images (1996, 2000 and 2005), we found the eco-environment changes of the northern wetland reserve area of Yellow River Delta during the three years. The distance from the Yellow River and soil salinity are important factors to control the macro-distribution of wetland types in the estuary wetland reserve area. Both of the natural factors (such...
Nowadays using uncertainty inference to predict the risk of soil erosion is a new development tendency. This paper attempted to simulate the distribution of soil erosion risk in a small watershed named Luoyugou (Tianshui, North China) by an uncertainty inference model based on Subjective Bayes and GIS. The results indicated that: (1) Land cover and slope are the fundamental factors to control spatial...
