摘要
通过对不同立地类型刺槐生长与水热状况相关分析,结果表明:在局部范围内,热量因子不是划分黄土高原立地类型的主导因子;水分与刺槐生长之间关系密切(r=0.8965)。说明水分是影响刺槐生长的主要因素,地形和土壤则是划分黄土高原立地类型的主要因子。
In accordance with the result of relational analysis between the growth of Robinia pseudoacacia and the situations of soil moisture arid heat capacity in different site types of loess plateau,situation of heat copacity isn't a dom- inative fartor dividing dfferent site types in partical in ranges leass plateau. The closer relations between the growth of Robinia pseudoacacia and soil moist- ure(r=0.8965)show the soll moisture is a major factor effecting growth of Robinia pseudoacacia,the terrain and soil are major factors dividing different site types of loess plateau.
