摘要
采用样地调查法、除趋势典范对应分析法(DCCA)研究戴云山自然保护区柃属蜜源植物种群空间分市格局及环境因子对其的影响。结果表明:戴云山柃属蜜源植物种群呈集群分布,海拔、坡向、破位、坡度等环境因子对种群分布和聚集程度存在不同影响;随着海拔高度上升,聚集度逐渐增强;阴坡与半阴坡的柃属种群聚集度较强;随着坡度增加,(?)属种群聚集度总体呈降低趋势。DCCA分析。
The method of sample plot survey and DCCA(Detrended('anonical correspondence analysis) were adopted lo investigate community in Eurya forest of Daiyun Mountain,the spalial distrihulion pattern and environmental factors were analyzed.The results showed that(1) Eurya nectar plant were contagiously distributed;(2) Aggregation was gradually increased with elevation gradient;(3) Aggregation was more strong on shady and semi-shady;(4) Aggregation was gradually reduced with elevation slope;(5) Elevation and slope position play a decisive role on the distrihulion of Eurya community in the reserve.
