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 on the lake area of Qinghai Lake grasslands have a very serious hazard. Locating the relationship between locusts and their ecological conditions is a prerequisite for the effective control of locusts. Different types of landscapes have different effects on locust occurrence through their redistribution of water and heat conditions. Based on the field survey data, the author conducted a preliminary study on the relationship between the occurrence of locusts in the lake area and the main geomorphological types and locust density in Lakeshore terraces, tectonic platforms and hillsides.
