摘　　要：川西林盘是四川特有的一种乡村景观类型和生态聚居聚落.为探讨川西林盘自然环境中植物群落的发展状况,走访成都平原范围内7市、5县的57个镇,共103个典型的川西林盘聚落,分析其植物物种组成和垂直结构,计算并探讨不同林盘植物群落的物种多样性、三维绿量.结果显示,共调查到229种植物,隶属于62科、113属,乔木层植物占据着最大优势,其多样性数值与三维绿量数值影响整体群落数值的走向呈正相关,也极大地影响整个植物群落的生态效益和景观效果;新型林盘虽然有较高的植物覆盖度,但群落结构丰富度和稳定性上不如原始林盘.从研究结果可知,恢复乡土记忆、改善部分植物群落的结构、优化土地利用方式是当前保护川西林盘生态系统的有效措施.Farmhouse forests in western Sichuan is a special rural landscape type and ecological populated settlements. To explore the development of the farmhouse forests＇ plant community in the natural environment conditions,we visited 57 towns in Chengdu plain＇s seven cities and five counties,in which we analyzed the plant species composition and vertical structure of 103 typical farmhouse forests settlements,calculated and discussed different farmhouse forests plant community species diversity,three-dimensional green quantity. To according to the results of investigation on 229 kinds of plants,involving 62 families,113 genera,tree layer plant occupies the biggest advantage,whose diversity and three-dimensional green quantity values was positively related to the direction of the whole community,also greatly affected the whole plant community ecological and landscape effect. Although new farmhouse forests have a higher plant coverage,community structure richness and stability of new farmhouse forests are less than original forests. The results of the study shows that restoring native memory,improving the part of the plant community structure,and optimizing the use of land are the effective measures of protecting the farmhouse forests ecosystem in western Sichuan province.
