摘  要:
[目的]明确气候和生境异质性对华北地区植物生活型分布格局的影响。[方法]根据Raunkiaer生活型分类系统对华北地区30个自然保护区的植物物种丰富度进行统计,分析华北地区不同生活型植物的物种丰富度分布格局,并采用SPSS软件对物种丰富度和环境因子进行回归分析。[结果]华北地区生活型谱以高位芽植物为主(46.04%),其次是隐芽植物(41.40%)和地面芽植物(32.86%),地上芽植物和1年生植物比较贫乏。回归分析表明华北地区植物物种丰富度主要受生境异质性和气候因子的共同影响:高位芽植物物种丰富度与海拔高差和最冷月均温相关,地上芽植物、地面芽植物以及隐芽植物物种丰富度均只与海拔高差相关,1年生植物物种丰富度与各因子的相关性都较小。[结论]海拔高差是华北地区不同生活型植物物种丰富度的主要影响因子,即生境异质性是影响华北地区植物生活型物种丰富度空间分布格局的主要因素。

摘  要:
[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 carried 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 richness 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.
