To understand the relationships between environmental factor and the grasshopper community in Ningxia grasslands, variables of the vegetation and grasshopper communities, and the relationships between the vari ables and the environmental factors have been equantitatively analyzed. By using the mathematical metheds such as path coefficiency analysis, canonical analysis and double screening for stepwise regression, 15 parameters for envi ronmental factors (8 paramettrs of them for plant community) were taken as independent varisbles, and 7 parame ters for grasshopper community were taken as dependent variables. The results show that the diversity of grasshop per species were positively correlated with the aridity index in habitat and the plant community with a greater com piexity of its family/species composition; that the dominance of grasshopper community were peitively correlated with the plant community of plant with a greater complexity of it vertical structure; in various subfamily of the grasshoppers, some speciec were clooely with the forbe grasslands and aridity habitats, while some species were asso ciated with gcod floral conditions. However, in the relationship between plants and grasshoppers, the effects of a gdri habitable c0ndition that were formed from the structure of plant community on some grasshoppers may be more important than that of the fed plants.

为了探讨环境因子与蝗虫群落的生态关系,本文运用通径分析、典型相关、双重筛选逐步回归等方法,以15项环境因子参数(其中包括8项植物群落参数)作为自变量,以7项蝗虫群落参数为因变量,对环境因子,特别是植物群落结构与组成的变化对蝗虫群落所产生的生态效应以及诸因子间的相互作用关系进行定量分析。结果表明:蝗虫种类多样性与环境干燥度和植物群落种类的复杂程度成正相关,与植物群落垂直层次结构的复杂性成负相关;群落优势度与植被盖度成正相关;不同种类蝗虫对不同类型草地选择性不同。总之,在蝗虫对植物群落的选择中,由植物群落结构所形成的栖境条件起着比植物类型更为重要的作用。
