中文摘要	【目的】对新疆艾比湖国家级湿地自然保护区,主要优势种植物组成的混生群落进行点格局分析。【方法】测定样方内每个物种的空间分布信息,运用Ripleys K(r)函数、L(r)函数和VR,分析其分布方式和群落总体关联度。【结果】(1)胡杨在0 ~ 25 m呈聚集分布,之后为随机分布; (2)柽柳在0 ~ 30 m呈聚集分布,之后为随机分布; (3)罗布麻在0 ~ 20 m呈聚集分布, 20 ~ 30 m为随机分布; (4)甘草在0 ~ 1 m为均匀分布,之后为聚集分布; (5)其他种群主要为聚集分布; (6)植物群落总体呈正关联,但不显著。【结论】艾比湖地区植物群落总体呈正关联,种群在小尺度范围内主要的分布方式为聚集分布,且在灌木群落中柽柳、梭梭种群竞争力强于其它灌木种群。
英文摘要	【Objective】This study focuses on the point pattern analysis of mixed community made up of the dominant plants in Ebinur Lake district: a national wetland reserve.【Method】The spatial distribution information of species were measured,and then their distribution pattern and general correlation degree were analyzed based on Ripley,s K(r) function,L(r) function and VR.【Result】(1) Populus euphratica showed aggregated distribution at 0-25 m,after that they were randomly distributed; (2) Tamarix chinensis chinensis exhibited aggregated distribution at 0-30 m,after that,they were randomly distributed; (3) Apocynum venetum displayed aggregated distribution at 0-20 m,and randomly distributed at 20-30 m; (4) Glycyrrhiza uralensis are evenly distributed at 0-1 m,then aggregately distributed; (5) Other species were mainly aggregately distributed; (6) Plant community was positively correlated in general,but not significantly【Conclusion 】The study indicated that in Ebinur Lake district,the community displayed a positive correlation in general. The species were mainly aggregated distribution on a small scale,and Tamarix chinensis and Haloxylon ammodendron had stronger competitiveness than other shrubs.
