中文摘要：

在张掖湿地采用随机抽样调查,对蝗虫群落组成以及发生规律进行研究。根据张掖湿地植被生态情况,将调查区域植被划分为芦苇湿地、碱荒地、人工绿化地3种生境。结果表明：张掖湿地蝗虫种类有3个总科,8科,18种。其中优势种有4种,即中华稻蝗、无齿稻蝗、东亚飞蝗、日本蚱,其捕获量占总捕获量的百分比依次为31.14%、17.04%、16.13%、10.73%。不同生境蝗虫群落的丰富度指数、多样性指数、均匀度3项特征指数,由大到小依次为碱荒地〉人工绿化地〉芦苇湿地,优势度指数由高到低依次为芦苇湿地〉人工绿化地〉碱荒地。张掖湿地蝗虫群落的发生规律为：5月中下旬蝗蝻出现,主要活动期出现在7月至10月,8月下旬种类和种群数量均达到高峰期,11月上旬蝗虫完全消失,不再活动。

英文摘要：

The occurrence regulation and community composition of locusts occurring in the wetlands of Zhangye were investigated by random sampling methodology. The investigated areas were separated to 3 parts, reed wetland, alkali wasteland, and artificial greenland according to the vegetation ecological situations. The results showed that there were 3 super families, 8 families and 18 species of locusts, among them,there were 4 dominant species,namely Japan itself,the Chinese rice locust, toothless rice locust, east Asia migratory locusts,and the percentages of catch to total catch were 10. 73%, 31. 14%, 17. 04%, and 31.14 %, respectively. The richness index, diversity index, evenness index of grasshopper community in different habitat were alkali wasteland 〉 artificial green land 〉 reed wetland. The dominant indexes were reed wetland 〉 artificial green land 〉 alkali waste land. Hoppers appeared in the last ten-day of May,the main activities emerged from July to October,both the species and populations peaked in the late August, and the locusts completely disappeared in the first ten days of November.
