In the dissertation, the theory and application of monitoring the habitat of Locusta migratoria manilensis Meyen were studied on the basis of reviewing the present research on the fields of locust habitat, the theories and methods to monitor its change, and the related technologies. Processed MODIS, ETM+, ground and aerial survey data were used to monitor the habitat of Locusta migratoria manilensis Meyen in the Baiyangdian Lake. As a result, the method and process were brought forward to monitor the habitat of Locusta migratoria manilensis Meyen in the Baiyangdian Lake.

本文在综述以往对生境、蝗虫、监测和预警等的研究和运用的相关技术基础上，分析了东亚飞蝗的发生、发展与其生存环境的关系，提出了东亚飞蝗生境监测的理论；并以白洋淀蝗区为例，开展了运用多源数据（MODIS、ETM+、航摄数据和实地调查资料等）融合方法对东亚飞蝗生境进行监测的应用研究；最后，提出了白洋淀东亚飞蝗生境监测的模式。
