Effects of Climate and Habitat Heterogeneity on the Distribution Pattern of Plant Life Form in North China
摘要
Abstract
Objective] To research the effects of climate and habitat heterogeneity on the distribution pattern of plant life form in North China. [ Method] Plant species richness of 30 nature reserves in North China was classified based on Raunkiaer life forms. We analyzed the distribution patterns of plant species richness for different life forms in North China. Regression analysis of species richness and environmental factors was car-ried out by SPSS software. [Result]The main life form distribution was Phanerophytes (46. 04%), followed by Cryptophytes (41. 40%) and Hemicryptophytes (32. 86%), while Chamaephytes and Therophytes were relatively poor. Regression analysis showed that the plant species rich-ness of North China was affected by habitat heterogeneity and climatic factors:Phanerophytes species richness was related to elevation range and mean temperature for the coldest month;Chamaephytes, Hemicryptophyte and Cryptophytes species richness was only associated with elevation range;Therophytes species richness had little correlation with environmental factors. [ Conclusion] Elevation range is the main impact factor of plant species richness for different life forms, and habitat heterogeneity is the main factor which affected the plant species richness distribution pattern in North China.关键词
