摘　　要：以三峡库区紫色土坡耕地栽种植物活篱笆的试验资料为依据 ,对坡地上如何布置植物活篱笆以及活篱笆的生长情况和初期效益进行了初步研究。结果表明 ,植物篱能有效防治坡耕地的土壤侵蚀 ,提高土壤肥力 ,增加地表植被 ,改变田间小气侯 ,具有投资小、施工简单、操作方便等优点。植物篱株距以 2 0～ 3 0cm为最佳 ,双行植物篱比单行植物篱挡土能力要强得多 ,植物篱梯田的形成时间约为 7～ 1The paper conducts preliminarily study on how to layout living hedges and the growing situation and initial benefits of living hedges planted on sloped lands based on the testing data of living hedges planted on purple soil sloped lands in Three-Gorge Reservoir area. The results show that living hedges can effectively prevent and control soil erosion, increase soil fertility and surface vegetation and change the microclimate of fields of sloped land. It also has the advantages of less investment, simple construction and convenient operation. The best spacing in the rows of living hedges is 20～30 cm. The retaining capability of double row transplanting is much better than that of single row and the building of terraced fields with living hedges takes 7～10 years.
