Research On The Health Evaluation Of The Land Use System In Changshou District Of Chongqing City

With the acceleration of urbanization,the social economic has been rapid development,while also facing a huge pressure of ecological environmental stress.Therefore,the system of the health status of the comprehensive land use of land based natural, social, economic is very important for the sustainable development of the society and population.So it is no is no time to delay to evaluate the health of the regionalism land use system.Changshou district as a major industrial area of Chongqing,the rapid development of its social,economic,has brought the huge pressure to the regional ecological environment,the land use system has a number of adverse consequences:an annual reduction of cultivated land by a big margin,farmland areas per person has a decreasing trend.Low idle land for construction.Severe soil loss.The average thickness of farming layer is decreasing,decrease environmental capacity and environmental capacity and so on.Therefore, the implementation of land use system health research work can provide a theoretical basis and guidance for the sustainable use of land resources, but it also can provide the degree of damage and degradation of land use systems where diagnosis caused by natural factors and human activities, managers to provide basis for decision making.Taking Changshou district as the research area,The data sources include the land use status data,social and economic data and environmental monitoring data of the Changshou district in 2000-2012 years.Analysis on the temporal and spatial variation of Land Utilization, the area of land use system health assessment by by using the method of comprehensive fuzzy analysis,and the use of gray model to predict their health. The results indicated that: in recent 10 years from 2010 to 2012,the spatial structure of land use type has undergone tremendous changes,which include changes in the data structure and spatial structure,and the change of cultivated land and construction land of the most prominent. From 2000 to 2012, the land use system health status of Changshou showed some volatility experienced unhealthy, there are three grade: the unthriftiness,critical state and sub-health.And the overall health of the land use system has improved,but there is still much room for improvement. The gray model results from the use of the land use system health point of view, the future of the land use system longevity health will be showing increasing trend in Changshou district.
