张家界市大鲵自然保护区金鞭溪流域植物生态位特征研究
|
摘要
通过分析张家界市大鲵自然保护区金鞭溪流域主要种群的组成及相互关系,以便合理地利用流域内树木资源,分别运用Levins生态位宽度指数、Hurlbert生态位重叠指数,剖析了流域内12种乔木的生态位特征。结果表明:12个物种按照生态位宽度值从高到低依次排序为玉兰(0.981)、篦子三尖杉(0.951)、水杉(0.915)、柳杉(0.684)、枫杨(0.585)、山茶花(0.491)、三峡槭(0.312)、枫树(0.308)、鹅掌楸(0.302)、含笑(0.287)、野桐(0.221)、榧树(0.201);区域内乔木之间的生态位分化不明显,生态位重叠程度普遍较高;各树种的重要值与生态位宽度指数并不总是趋向一致。
The composition and interrelation of the main population of the Jinjiaxi watershed of the giant salamander nature reserve in Zhangjiajie are analyzed in order to rationally utilize the tree resources in the basin. On the basis of the investigation, 12 tree populations' niche characteristics in the Golden Whip Stream of Zhangjiajie giant salamander nature reserve speciesby are analyzed using the Levins niche breadth Hurlbert niche overlap index. In accordance with the 12 species niche breadth values from high to low in turn order is listed as follows Magnolia denudata(Desr)(0.981), Cephalotaxus oliver(0.951), Metasequoia glyptostroboides(0.915), Japanese cedar(0.684), Pterocarya stenoptera(0.585), Camellia japonica(0.491), Acer wilsonii(0.312), Maple(0.308),liriodendron chinense(0.302), Magnolia figo(0.287), Mallotus japonicus(0.221), Torreya grandis(0.201). There is a high degree of niche overlap among regional populations, and the niche differentiation is not obvious in the direction. The important value of species in the region and the niche width do not always show obvious consistency.
