- Abstract:
- Climate factor and soil moisture are the important influence factors responsible for soil and water loss. Combining the climate factor with the terrain humidity index for analysis, it can be good at forecasting the soil and water loss. In this paper,with the Xilinhaote as the analysis area, nearly 10 years climate change trend in Xilinhaote city was analyzed using Excel. The results showed that the average temperature and average wind speed increased, while amount of precipitation reduced. Climate change made the ecological environment worse. Base on the DEM of Xiinhaote, the terrain wetness index can be calculated by using the analysis function of GIS. According to the administrative division, the smaller terrain wetness index area can be identified. Based on climate change and the terrain index, it was found out that the moisture content of Maodeng pasture, Baiyin shearer pasture, Baoligen sappanwood was lower; these three areas were much easy to suffer wind erosion. The measures should be taken to reduce unnecessary soil and water loss caused by human activities.
