Evaluation Study On Sustainable Utilization Of Land Resource In Rucheng County Based On BP Neural Network

Land resources is one of the human society’s most valuable natural resources.Conflict between people and land have become increasingly prominent with the development of urbanization, and sustainable use of land resources become the focus of attention of policy makers and researchers. To carry out the land sustainable use assessment, and of great significance to promote balanced regional development. County economy is an important component of China’s provinces, municipalities and economic, to promote agricultural development, the county also led the development of secondary and tertiary industries, the county’s township enterprises and private enterprises to become major growth point for China’s national economy. Between population, resources, environmental problems have become increasingly prominent with the development of county economy, there is the need for the county, the sustainable use of land resources development.Rucheng County, for example, on the basis of relevant research, starting from the basic theory of sustainable use of land resources of Rucheng as a system, combined with the natural and socio-economic status of the county on county land use characteristics and existing problems in land use analysis, and on this basis in accordance with the principle of sustainable land use indicators selected, selected22evaluation of Rucheng land sustainable use of evaluation index system.BP neural networks are highly nonlinear, high fault tolerance, self-learning and adaptive capacity, etc., used in land resources, sustainable use of human factors evaluation to a greater extent to avoid interference, and strong objectivity. In this paper, BP neural network as a platform constructed of Rucheng Sustainable Land Use in the evaluation of BP neural network model, Hunan Province, the data for training samples, evaluation of Rucheng sustainable land use from2001to2010the degree of the results show that the Rucheng County land use mainly in the initial sustainable state, and presents a growing trend. Finally, sustainable use of Rucheng land proposed to make a few possibilities...
