The Study, Based On Remote Sensing Of Cultivated Land Warning And Vegetation Dynamic Monitoring

Land use change survey with RS and GIS imagery has been one of the important methods for the land manage apartment to understand and accommodat land resource -es, and has attracted universal attention.This thesis firstly analyzes the RS monitoring programs on vegetation eco-environment and illustrates the signif cance of vegetation eco-environment evaluation based on RS information model. Secondly, with vegetation eco-environment as the object of RS monitoring, the thesis introduces the establishment of the related RS background value and the abstraction of the indexes of the key factors involved. Based on linear fitting method, detailed steps of establishing vegetation eco-environment's RS background value are summed up. This helps set up the value system required in extensive application of RS technology in vegetation eco-environment evaluation and establish the relevant technical methods of RS monitoring. Thirdly, mufti-source RS information from various sourcesis employed to establish RS evaluation models, which are used to establish an RS background value and then evaluate the current situation of the vegetation eco-environment of the research area. Lastly, summarizing the technology and the method , and giving the expectation.This thesis exist in'The RS monitoring of eco-environment and cultivated Land in Yangtze River Delta'.The project Provides the science and technology support for the eco-environment and the tilth resources management and the protection.Is helpful in the formulation science reasonable resources use order, realizes the region sustainable development.
