Abstract


Land use change is a global environmental change most significant aspects, both by natural factors, but also by social, economic, technological and historical factors, with strong regional and integrated, while the global environment change has a direct effect, and thus become one of the hot research at home and abroad. Land Use Change Zhungeer mainly through regional case studies, summarizes the temporal and spatial land use change, and analyzed the main driving factor, and establish a regional land use patterns. Such a regional scale in different case studies is to further knowledge and understanding of the whole of China caused by land use change carried out various driving factors, its comprehensive study of land use change provides a rich and valuable regional information . Zhungeer as arid and semi-arid ecotone typical representative of the physical geography has its unique spatial distribution pattern and ecologically fragile with significant habitat characteristics and differentiation law, and has a long history of land development . Due to its special natural and geographical characteristics and the social, economic, and political factors driving complex, since the founding of the area's land cover had undergone rapid and profound changes, with these changes in agriculture, forestry, animal husbandry and land resources industrial development and use of relevant land degradation, urbanization and sustainable development issues are closely related. Depth analysis of the structural stability of land use and land use change in the main driving force, and in order to adjust the rational planning and development of land resources, land use structure optimization is both rational way, but also protect the environment and achieve sustainable development of the fundamental requirements of regional . Firstly, the study of land use change on scientific significance and abroad were reviewed to socio-economic statistics reveal Zhungeer based and land-use change related regional natural features, land use change and land use change Brief History the basic trend. Then this paper analyzes the Zhungeer and changes in land use structure laws of time and space, land quality changes, analyzes the driving factors of land use change. Finally, in theory under the guidance of sustainable land use, land-use development patterns as the goal, made Zhungeer sustainable land use in specific ways: Subdivision of land use configuration mode. Through the above analysis, the article draw meaningful conclusions about the following: (a) between 1987-2000 Zhungeer land use occurred in the number of large changes. Specific performance: unused land and a significant reduction in arable land, while woodland, grassland, orchard, traffic land, construction land increased significantly. However, changes in land use structure townships vary. (2) Since the founding Zhungeer land reclamation rate from the 1950s to the late 1970s gradually decreased, while rapidly increasing throughout the 1980s. Land use and irrigation efficiency index has been steadily increasing. (3) Zhungeer socio-economic conditions since the founding of the population increase of less than 3 times. Total grain production and yield rising grain acreage has been decreasing, per capita food production changed little. To diversify the agricultural structure. (4) changes in land quality Zhungeer mainly as follows: Available on the land decreasing; land productivity decreased; energy base developed land contamination. (5) Zhungeer land use change driving these factors mainly: people o, economic development, infrastructure, policies and so on. Back (6) Zhungeer land use should be on the way to sustainable use management and development; and ecological development model should be based on the fundamental objective, adhere to local conditions partition of land use configuration mode.
