The Study Of Ecological Effects Of LUCC

Land use/cover change is one of the core issues of the current research in the field of global change, it is not only important part of the global change, but also the main impact of global environmental change reason. The land-use change will inevitably lead to changes in land cover, land cover change caused by subsequent land use changes in the way. Since the mid-20th century, with the rapid population growth, the improvement of production and living requirements, environmental pollution increase, the emergence of global energy and resource shortages, and many other major issues, land use/cover change in the geographical environment and human living environment intensifying land use change can cause a lot of changes in natural and ecological aspects of land use change and its impact on the ecological environment has important implications for the understanding of the regional ecological environment.This paper had all regional overview, as the main technical support to GIS means extensive collection of information on the basis of analysis of20years1989-2009, the land use/cover change and its ecological effects. Had all throughout the area and the distribution based on remote sensing image data and statistics, analysis of the current characteristics of land use Zengdu District; Secondly, from the number and extent of regional differences of land use dynamic changes in status; analyzes the driving factors that lead to land-use change, mainly due to the impact of the four aspects of the natural, social, economic, demographic and policy; Finally, quantitative analysis of the eco-environmental effects of land use change The results showed that had the value of ecosystem services in all areas is a downward trend, mainly because of the rapid development of the economy and the ecological benefits at the expense of the environment.This paper is divided into five parts:The first part on land-use change and its ecological effects theory research background, significance, research status and the research purpose, research content and methods, technical route.The second part of the principles and methods of this study. Papers on the basis of the theories and methods of analysis of land use and ecological effects, select the main research methods and models, mainly single land use dynamic analysis, the transfer matrix model, ecosystem service value evaluation model.The third part is the empirical research, qualitative analysis had all the natural and economic profiles, land resources utilization and data processing. Results and discussion sectionThe fourth part, based on the model calculation results, analysis of the dynamic changes had all land use and its driving factors had all areas of the value of ecosystem services and their evaluation.The fifth part of the conclusion of this article and research.
