摘　　要：生态景观林是乡村生态景观与文化传统的必要组成部分,更是生物多样性生存的重要栖息地。为了探讨乡土植物群落构建和村落植被恢复对生物多样性产生的影响,以浙江省历史文化村落安吉县繅舍村为例,调查、分析了毛竹林、板栗林和水杉林林下植物分布,以及生态景观林营建对植物多样性变化的影响。结果显示,毛竹林林下灌木植物种类最为丰富,达到36种;板栗林分灌木层Shannon-Wiener指数、Simpson指数和物种丰富度分别为1.96、0.81和12,显著高于未改造的纯林林分,草本层植物多样性变化不明显。研究结果表明,与纯林林分相比,以乡土植物群落为主构建的生态景观绿地提高了灌木层植物物种多样性,有利于改善区域环境,提高林地生态效益。Forest landscape was a necessary part of rural ecological landscape and traditional culture, which provided important habitat for biodiversity. In order to study effect of rural ecological landscape construction on biodiversity, a village called Saoshe in Anji County of Zhejiang Province was taken as a case study, and the plant diversity of Phyllostachys heterocycla forest, Castanea mollissima forest and Cunninghamia ianceolata forest, as well as biodiversity variation of the transform stands, were analyzed. The results showed the bamboo understory shrubs species are most abundant, up to 36 kinds; Castanea mollissima stand shrub layer Shannon-Wiener index, Simpson index and species richness were 1.96, 0.81 and 12, significantly higher than that without modification of the stand, while the herb layer species diversity changes was not obvious. The analysis results showed shrub layer species diversity was increased under forest landscape transformation, and pure forest stand environment and ecological benefits of forest was improved.
