[目的] 进行江西省水土流失重点防治区的复核和划分,为科学编制江西省水土保持规划提供依据. [方法] 在继承江西省原"三区"划分成果的基础上,利用第一次全国水利普查江西省水土保持专项普查成果,以县级行政区为单元,按照统筹考虑水土流失现状防治需求,与已有规划成果相协调,集中连片,定量分析为主,定性分析为辅以及等级从高等原则的要求,采用"2+1"和"双达标"的模式,进行了复核划分. [结果] 复核划分确定了10个江西省省级水土流失重点防治区,土地总面积66 562.6 km2,占全省土地总面积的39.9%,并提出了江西省水土流失防治总体方略及不同重点防治分区的防治途径. [结论] 研究结果可为全省水土保持工作和宏观决策,加快推进江西省生态文明先行示范区建设提供了重要的依据.
[Objective] The objective of this study is to analyze the recheck and division of key prevention and controlled area for soil and water loss in Jiangxi Province in order to provide the basis for soil and water conservation planning in Jiangxi Province. [Methods] Based on the original division of the "three district" in Jiangxi Province, we used the soil erosion data from the first national water resource survey to recheck and divide the soil erosion control zone. A county(administrative area) was taken as a unit in division. The requirements for soil and water loss in key prevention and controlled area, and the existing planning results were considered. Quantitative analysis, and the"2+1" and "double standards" patterns was employed. [Results] There were 10 key prevention and controlled area with soil and water loss, which accounted for 39.9% of the total area in Jiangxi Province. The strategies for soil erosion prevention and control were proposed. [Conclusion] The results of this study can provide basis for soil and water conservation and governmental macro policy decision in Jiangxi Province in the future.
