摘要：本文采取样地调查法研究徐州市三类居住小区即安置小区、传统居住小区、别墅小区的三类居住绿地即中心绿地、宅旁绿地、道路绿地中的群落物种构成、物种多样性和物种数量特征，利用Excel软件进行数据统计，比较分析徐州市不同类型居住小区内不同类型绿地植物群落物种多样性的差异。结果表明：就乔灌层而言，在Simpson指数、Shannon-Weinner指数和Pielou均匀度指数方面，均为别墅小区>传统居住区>安置小区;在别墅小区和传统居住小区内，在Simpson指数和Shannon-Weinner指数方面，为中心绿地>宅旁绿地>道路绿地，而在安置小区内为宅旁绿地>中心绿地>道路绿地，在Pielou均匀度指数方面，均为宅旁绿地>中心绿地>道路绿地。并结合三类居住小区物种重要值和综合物种重要值对徐州地区各类型居住小区的植物选择提出建议和意见。39675

Analysis on the difference in plant species and arrangement of different residential communities in Xuzhou
Abstract：The paper used the samlping method to study the species composition,species persity index and species quantity characteristics in three types of residential districts green space which are centre green space,green space between houses and road green space .The three types of residential communities include resettlement residential community,traditional residential community and villa community in Xuzhou,then this paper compared and analyzed the persity index about different residential districts green space of different residential communities on base of the Excel statistics analysis.The result showed that in arbor and shrub layers the values of Simpson index, Shannon-Wiener index and Pielou evenness index is villa community>taditionnal residential community>resettlement residential community ,and in villa community and traditionnal residential community,the order of values Simpson index and Shannon-Wiener index is centre green space>green space between houses>road green space，but in settlement residential community is green space between houses > centre green space >road green space.The order of Pielou evenness index in all types of residential communities is green space between houses > centre green space>road green space.Some advices and views about the selection of plant in Xuzhou are provided concerned the importance-value index of three types of residential communities and comprehensive importance-value index.

居住区是人们在城市中以群体形式聚居生活，形成规模不等的居住区域。居住绿地在城市中是居民相距最近，接触最频繁，分布最广泛，最受欢迎一种城市绿地应用形式。城市用地中生活居住用地一般占整个城市用地的50%—60%,而居住区用地占生活居住用地的45%—55% [1]。
