摘要
蝗虫对青海湖环湖区的草地有相当严重的危害．摸清蝗虫发生与其生态条件之间的关系，是进行蝗虫有效防治的前提．不同类型的地貌通过其对水热条件的重新分配对蝗虫的发生有不同的影响．作者根据野外实地调查资料，就环湖区蝗虫发生与湖滨阶地、构造台地及山坡地等该区主要地貌类型与蝗虫密度的关系进行了初步研究．
Grasshoppers are seriously harmful to the grasslands of the region around Qinghai Lake. The prerequisite for the effective control of grasshoppers is to clarify the relationship between grasshopper occurring and its ecological conditions. The different types of landform have different effects on grasshopper occurring through their redistribution of heat and moisture conditions. Based on the data collected in the field, the relationship between the major types of landform such as lake-shore terrace,tectonic platform and mountain slope in the region around Qinghai Lake was explored in this paper.
