摘要
通过对黑龙江省松嫩草原植被盖度、多度和频度的调查分析,将植物群落抽象地概括到两个排序轴上,再应用相关分析,确定不同地点的主要气候因子,结合这些主要气候因子与土壤因子,分析各因子与排序轴间的相关性,确定影响群落分布的主导因子。
Cover, abandance and frequency of about 80 species plants on the Songnen grassland were investigated Spatial distribution of vegetation was Summarized in two main Axes of RA And the correlationship coefficients between ecological faetors and site faetors were estimated The relationship betwecn two ordinate axies and enviromental factors including main ecological factors and selected soil factors was analyzed Based on these analyses, the characteristic of distribution was discussed
