江西省水土流失现状与发展趋势分析

基于第一次全国水利普查江西省水土保持情况普查数据，分析了江西省目前水土流失的总体变化状况以及不同区域的水土流失分布特征，并结合历史上水土流失调查及普查数据分析了江西省水土流失的发展趋势。结果表明:2011年与2000年相比，土壤侵蚀总面积减少了6 975.32 km²，减少幅度为20.84%，中度以上各级土壤侵蚀强度的面积均有不同程度的减少，该省水土流失总体上在减轻，水土流失的形势在向好的方向发展。但随着全省经济发展和开发建设项目增多，局部人为恶化水土流失的现象仍将长期存在，水土保持工作任务依然艰巨。

Current Status and Developing Trend of Soil and Water Loss in Jiangxi Province

Based on the soil erosion data of the first national water resource survey, we analyzed the present status and dynamic changes of soil erosion in Jiangxi Province. Simultaneously, we also analyzed the developing trend of soil erosion by using the soil erosion survey data in history. The results showed that, comparing with 2011 and 2000, the total area of soil erosion in Jiangxi Province reduced 6 975.32 km², the decrease rate was 20.84%, each area of more than moderate levels of soil erosion intensity reduced at various degrees; the overall situation of soil erosion in this province became better, and the situation of soil conservation has been developing at the good direction. However, with the economic development and increase of development and construction projects in this province, soil erosion caused by human activities will still exist for a long time, therefore, the works of soil and water conservation will still face the serious challenge.
