摘要： 为了准确定量评价退耕雷竹林水土保持功能，利用模糊数学和多元统计分析原理，对不同类型退耕雷竹林的水土保持功能进行了综合评价。结果表明，退耕雷竹林地水土保持综合指数均大于耕地，其中以（1年生:2年生:3年生:4年生比例为2:3.5:3.5:1+密度为9000~15000株/hm2+施有机肥30000 kg/hm2和施复合肥3000 kg/hm2+覆盖）模式经营的退耕雷竹林水土保持综合指数最高。此结果可为雷竹林水土保持功能的调控提供依据，对于促进雷竹林水土保持功能发挥具有重要的现实意义。

Abstract: In order to evaluate the soil and water conservation function of Phyllostachys praecox cv. Prevernalis stands returned from farmland. Based on fuzzy mathematics and multivariate statistical, the soil and water conservation function of Phyllostachys praecox cv. Prevernalis stands returned from farmland under different types had been comprehensive evaluation. The results showed the comprehensive index of soil and water conservation function of Phyllostachys praecox cv. Prevernalis stands returned from farmland granter than farmland. The Phyllostachys praecox cv. Prevernalis stand returned from farmland with proportion of 2:3.5:3.5:1, density of 9000-15000 culms/hm2, organic fertilizer 30000 kg/hm2, compound fertilizer 3000 kg/hm2 and mulching method had the highest comprehensive index of soil and water conservation function. These results could be provide the basis for the regulation of soil and water conservation function of Phyllostachys praecox cv. Prevernalis, and it had important practical significance to promote of soil and water conservation function of Phyllostachys praecox cv. Prevernalis stands returned from farmland.
