| 摘 要： | 由于坡向、坡度、坡面与坡位的不同,导致水热及光照再分配,形成山地复合体,产生了不同的草地类型。本试验研究草原与荒漠草原复合体植物群落主要牧草重要值的差异,用SPSS软件包对其差异进行分析,分析影响山地复合体草地植物重要值的主导环境因子,结果表明,温度及光照是其主要影响因子。

| Abstract: | As a result of the difference of slope direction, slope angle and slop position, water, heat and light were reallocated, which results in compound body of mountain and different grassland types. In this study, we tested the difference of important value of phytocoenosis between grassland and desert grassland and tried to identify the major environment factors. All data analyses were performed by using program SPSS. The results showed that temperature and light were the main factors. |
