摘　　要：川西林盘作为成都平原城乡一体森林生态网络体系的重要组成部分,高度的生物多样性造就了极其丰富的景观层次。该研究参照成都市城乡建设委员会提出的川西林盘的分类方式,结合川西林盘现状,采用样线法选择了183个典型川西林盘,通过景观单元与植物群落的关系分析研究,剖析其与物种多样性之间的关系,为川西林盘保护提供参考依据。结果表明:1)部分自然景观要素逐渐消失,景观要素缺乏一定的完整性;2)景观单元趋于单一化和简单化,体现生产技术的进步与居民生产方式的转变;3)景观要素的多少,在一定程度上能对物种多样性指数产生影响,相对复杂的景观单元,能促进植物群落和川西林盘的稳定发展。As a key component of the urban-rural integrated forest ecological network system in the Western Sichuan,the Linpan in Western Sichuan has a high level of biodiversity,which has created an extremely rich landscape.Based on the classification method of Linpan in Western Sichuan proposed by Chengdu Urban and Rural Construction Committee and the current situation of Linpan in Western Sichuan,183 typical Linpan in Western Sichuan were selected by using the transect method.The relationship between landscape units and plant communities were analyzed.The relationship with species diversity provided a theoretical basis for forest disk protection in Western Sichuan.The results showed that,1)some natural landscape elements disappear gradually,and the landscape elements lack certain integrity;2)the landscape unit tended to be unitary and simplified,reflecting the progress of production technology and the change of residents’ production mode;3)the number of landscape elements could affect the species diversity index to a certain extent.The relatively complex landscape units could promote the stable development of plant communities and Linpan in Western Sichuan.
