摘要
采用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。,香农-;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。本研究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。

ANALYSIS OF MUNITY STRUCTURE AND SPECIES DIVERSITY OF RESIDENTIAL AREAS OF LUOYANGCITY
ABSTRACT
A 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. Western District of stream has been selected as a 3 point, . the flower city, century century Hua Yang and Nanshan district shaft life; the work area as a 2 point difference is on Broadway Tang Chong Yang Road and Los dragons munities, selected 3 as a point of Henan University of Science and Technology family homes, Garden homes, and Luoyang Polytechnic families rich green garden and landscape. Results showed that: Luoyang city residential areas as a whole, plant species rich, 42, 121, 203, and is properly configured, a better visual impact. Simpson's Index Average greater than -d, the Shannon Index, an average of greater than ; species diversity, rich wetland plete, the growth in production is more reasonable. But there are also a number of problems, such as color, species richness is the number of applications, but there are relatively few shrubs; and positive trees shade the upper layer of the growth conditions. This study analyzed the types of green plants, the quantity, frequency, and plant species richness, and thus to the Luoyang city residential green building provides scientific information and theory.
