河 南 科 技 大 学毕 业 设 计(论 文)洛阳市住宅区植物的群落结构与多样性分析 姓 名 院 (系) 林 学 院 专 业 园 林 指导老师 2012 年 5 月 25 日摘 要采纳抽样调查法和实地走访,在洛阳市 3 个辖区选取了 8 个居住区作为样点,对洛阳市住宅区植物群落结构及物种多样性进行了调查分析。其中涧西区选取了 3个样点,即中泰世纪花城、世纪华阳和南山洛轴生活区;西工区 2 个样点分别是盛世唐庄和上阳路社区;洛龙区选取的 3 个样点为河南科技大学家属院德园、洛阳理工家属院绿园和山水富地。结果表明:洛阳市住宅小区整体来说,植物物种丰富,有42 科,121 属,203 种,配置合理,景观效果较佳。辛普森指数平均大于 0.6,香农-维纳尔指数平均大于 1.3;物种多样性较丰富,植物群落结构较为完整,生长型谱较合理。但也存在一些问题,比如彩色叶树种种类较为丰富,但是应用数量相对较少;而且阳性灌木因受上层乔木遮荫而出现生长状况稍差。本讨论分析了绿化植物的种类、数量、应用频率、植物物种丰富度等,从而为洛阳市的住宅区绿化建设提供科学参考和理论依据。关键词:洛阳市;住宅区;群落结构;多样性分析;植物配置 ANALYSIS OF THE COMMUNITY STRUCTURE AND SPECIES DIVERSITY OF RESIDENTIAL AREAS OF LUOYANGCITYABSTRACTA sample survey and site visits, and Luoyang City in 3 districts has been selected as a 8 as a residential area of Luoyang City, residential area wetland structure and species diversity in the analysis of the survey.
