A Study Of Xinjiang Shanshan County's Land-use Change Detection

Since 1972, the United States launched the first Land Resource Satellites, Earth observation satellite developed rapidly, its application field and application effect is expanding constantly improving. Due to the remote sensing technique can provide the best information acquisition modes, and not block etc, terrain, rapid, real-time bestrew scope, high spatial resolution ,high resolution and high resolution phase, etc. After nearly 30 years of development, use the remote sensing data collecting earth changes has become a the important information and technology, and has been widely permeates every field of national economy.In the 1980s, the United States, Japan and the European space agency have proposed to the earth observation plan (EOS), remote sensing image of land use change detection, has had more and more concern of researchers, but traditional land use/covering mainly through the field detection method based on field measurement or check Pictures for linear-ring .This kind of method is obtained in time inconsistency, big workload, time-consuming, the difficult to update (Shi Peijun, 1996). Updating the LUCC state data and information rapidly has become a technical problem in fields such as Remote Sensing and Geographic Information System. The research on how to accurately and rapidly discover the change of geographic data we have had, and how to automatically extract the needed change-information from the image. The theory and technology for LUCC maps'updating, covering has important significance (Hanging Mu2002) this paper is sincerity based on these topics.This article, in view of the development of the land use change detection which based on remote sensing image, raise the change detection methods which are used regularly, through comparison and analysis, using remote sensing detection methods of classification comparison. used the Shanshan county region'remote sensing images in 1990, 1999 and 2008 and phase land use status in 91 and 2005, the study of remote sensing data, and discusses the three process change detection: image preprocessing, change information acquisition and the concrete implementation process, later, article used the result of land use based on information dynamic model is analyzed and studied area of land use changes, and simulated forecast.
