摘要
以环青海湖地区这一蝗灾高频发生的生态脆弱区为研究区 ,以 1997～ 1999年观测资料和有关历史资料为基础 ,比较系统地分析和阐明了该区草地蝗虫数量的空间分异规律及其与地形条件、土壤性质、植被类型等生境要素之间的关系 。
Based on the investigation from 1997-1999 and the historic data, this paper presents the rules of locust distribution in areas surrounding Qinghai Lake, elucidating the relationship between the locust plague with factors of habitat including topology, soil property and vegetation types. Results of the study would be of importance for setting up models of locust plague forecast and prevention.
