| 摘 要： | 水土保持区划工作是水土保持工作中的基础工作,而水土保持区划指标体系的建立则是水土保持区划中的关键步骤。新水土保持法颁布之后,新一轮的江苏省水土保持区划工作目前尚处于起步阶段,如何选取区划指标,又选取哪些区划指标来综合反映影响江苏省水土保持的因素至关重要。从确立江苏省水土保持区划指标体系建立的原则出发,并结合了江苏省自然、社会、经济、土地利用和水土流失等要素的情况及其特征,从中选取了22个江苏省水土保持区划指标。然后采用主成分分析法从22个区划指标中提取了15个主成分,并计算出各主成分的权重,最终建立了江苏省水土保持区划的指标体系。

| Abstract: | To establish the index system is the key step of the regionalization of soil and water conservation which is the basis of soil and water conservation.The new regionalization work is]ust in its starting stage in Jiangsu Province after the new law decide how to choose the index.22 on soil and water conservation was published,at which it is important to indexes were selected based on the design principles of index system of soil and water conservation regionalization,combined with the characteristics of natural,social,economic conditions and land use and soil erosion and water loss situation in Jiangsu Province,from which 15 indexes were extracted by principal component analysis,calculated with the weight of every component,and finally the index system established. |

| Keywords: | principal component analysis regionalization of soil and water conservation index system Jiangsu Province |
