Based On The Ecological Security Of Chaohu Lake Watershed Land Use Research

With the development of global economy,the human demand for land resources has reached unprecedented degree.Unchecked development and utilization,resulting in direct and indirect ecological damage.Arable land descreased sharply causing food shortages,soil erosion and desertification,water pollution and by different degree of soil erosion and pollution.How to ensure the ecological environment of land resources to fundamentally solve the ecological problems of land resources,the optimization of land use structure,the optimal design of reasonable and effective way in land use security layout design,has become an important topic in the the current research of land resource sustainable use.Chao lake basin located in central anhui province,famous of chaohu lake(one of the five fresh water lake of famous).Back against the provincial capital of hefei,hefei,chaohu lake and other nine cities and counties in the region,has always been our province political economic and cultural center and the important agricultural products base in the middle and lower reaches of the Yangtze river region.As the regional economic development speed in recent years,more is known as the industrial corridor along the river,is the first area of anhui province accelerated into the Yangtze river delta economic circle,has important economic and strategic status of the environment.But the urban economy development and utilization of large-scale,also causes the variation of land ecological environment of the basin,direct expression in the area of land ecological regulation of resilience has fallen sharply,and there is growing momentum.In this paper,through the collection of data and the existing knowledge system study,plans to study steps in the following six parts:1.Introduced the background,the purpose of this study and the research of social significance.At the same time the research status of ecological security of land resources at home and abroad were reviewed,in order to determine the research content of this paper and the corresponding use of technical route.2.To be familiar with the theory of knowledge in the process of research in detail,combined with the leadership of the party thought at present stage,with five major development concept,the sustainable land use,land expression theory,land use planning,and pronounced theory thought basis for two type society,guided by the ecological security of land resources to complete the study of this paper.3.The research object of chaohu lake basin,the natural environment,social conditions,land use status,nearly 10 years of land use structural change and the resulting land resourcesecological problems for detailed analysis.4.Collect a decade of chaohu lake basin use change data of land resources,analyze the impact of land use change on the ecological environment,study how to coordinate the relationship between land use and ecological environment,to construct the construction of environment-friendly land ecological security.5.According to the qualitative and quantitative analysis,induction,data investigation conclusion value,the method of combining analysis on the influence of land use change in the ecological service value,and then establishes the rules of the protection for the land ecological security,land put forward development and consolidation of cultivated land protection and Suggestions by the guidance of the concept of five development countermeasures of land ecological security,.6.The conclusion proposed countermeasures on the basis of data analysis,in order to maintain ecological security,realize the ecological sustainable development of land resources.
