Resources and environment is the foundation of survival and development of human society, in recent years, socia-economic development increase rapidly, the shortage of resources more and more seriously and the environmental issues also exacerbate. Evaluation of the resources and environment evaluation carrying capacity plays a important role in regulating the human activity and using and protecting the resources and environment, therefore, the results of resources and environment carrying capacity evaluation do have vital significance for realizing the local economic development in harmony with population, resources and environment.Combined with the basis of relevant theories, the analysis and summary of related research progress at home and abroad, taking luoping county of Yunnan province as the study area, using the global principal components analysis method and the GIS spatial analysis method, dynamically evaluates the luoping resource and environmental bearing capacity. On the basis of the evaluation results, the luoping space differences of the bearing capacity of resources and environment is analyzed for ten years. Through analysising and studying, the results is shown as following:The key factors to influence the luoping resource and environment carring capacity is natural resource factors, environmental factors and social economic conditions. Luoping county in the selected calendar year respectively calculated score and ranking of the four principal components, the result shows that the first principal component reflect seven indexes of information, it playes key role for resource environmental bearing capacity of the town of Luoxiong, limits the Lubuge township; The index information of second principal component has no limit on the resource environmental bearing capacity of Lubuge township, but has the largest limit on the resource environmental bearing capacity of Zhongshan township; The index information reflected by the third principal component has little limits on the resource environmental bearing capacity of Lubuge township, has the most seriously restrict on the resource environmental bearing capacity of Jiuwuji township; Per capita water availability has little limits on the resource environmental bearing capacity of Lubuge and Zhongshan township, has the most seriously restrict on the resource environmental bearing capacity of Dashuijing township.Luoping county area resources and environment carrying capacity exist a lot of differences in time and space. As the change of time, with the development of social economy, in ten years from 2005 to 2014, it shows a increasing trend of luoping resource environmental bearing capacity. From the analysis on space, Luoxiong town which having good social and economic conditions has the strongest resource environmental bearing capacity, resource environmental bearing capacity of the Jiuwuji township is weakest. |
