内容 研究概要:Xinjiang is a typical arid region with a large area of land. Because of the complexity and diversity of natural conditions, land utilization and land covering situations change diversely. There are three main land utilization types as mountain, desert and oasis utilization. Grassland utilization is the main part and agricultural utilization of oasis land is the most important type. Under poor management, the benifits of land utilization are also poor and land degradation, such as desertification, secondary salinization and swampiness, is serious. The changes of land covering are affected by population, human activities, regulation and distribution of water resources, selection and adjustment of land utilization trends, social and economic factors, etc. The remote-sensing technique could be used in the investigation, analysis and monitoring of grassland and forests in mountains, of oasis scale and its evolution, of environmental changes of plain water, of vegetation changes on the transition belt between oases and deserts, and of development of soil salinization and swampiness in oases. Locating in the hinterland of Asia-Europe Continent, Xinjiang is a typical arid region with the annual precipitation of 154mm and the annual evaporation of 2000mm to 3000mm. Because of complexity and diversity of natural conditions in the large area, the land utilization types are also abundant and diverse. The study of land utilization and land covering in Xinjiang concerns with the environmental study very much. The remote-sensing technique is an effective means in the study of current situations and changes of land utilization and land covering.
