Abstract


Forest resources is a product of the development of the Earth’s ecosystem, it is also an important component of the Earth’s ecosystem and the material basis of human life, which effective and sustainable use the forest resources has become the key for the entire human ecological environment to maintain and improve. In control of and understanding the development status of the forest resources spatial structure could be better management of forest resources and to achieve sustainable development.In this paper, with the sustainable development strategy as a guide, from the needs of the space development of the modern forest resources and environmental management, with the geography study of the forest resources spatial structure theory and their own space-time development rule and the impact of human activities, on the basis of the predecessors study of the forest resources spatial structure, analyzed the forest resources spatial structure status, temporal and spatial changes, trends, driving factors of the Three Gorges reservoir area in western Hubei, evaluated and forecasted the regional forest resources spatial structure, and build a technical support information systems.At the beginning of the needs of the forest resources sustainable management, based on the analysis of the characteristics of forest resources spatial structure, and development rule, the formation mechanism of the forest resources spatial structure, spatial analysis technology and methods of the space structural theory and application actuality, put forward the point of view which the forest resources spatial structure of the reservoir area were formed in the natural, economic and social environment, and other factors under the interaction and development, point out that the forest resources spatial structure of the reservoir area and forest resources sustainable development is closely related to.From the point of view of the systemic theory to discuss the development mechanism of forest resources of the reservoir area, Combining research in the investigation of forest resources in the reservoir area, the application of GIS technology for spatial data collection, collation and analysis, to establish temporal and spatial changes forecast model; Through the establishment of forest vegetation cover index change models, the center of gravity transference models, traversed the temporal and spatial changes rules of the forest resources in Three Gorges reservoir area, and expatiated the impact ways and strength of the different factors of the forest resources, reveals the spatial variation drive mechanism of forest resources in Three Gorges reservoir area.Based on the integration analysis of the status, impact factor, spatial movement status of the forest resources in Three Gorges reservoir area, the forest resources spatial hierarchical structure appraisal target system mainly by stability criteria was proposed. By establishing many kinds of target weight computational method, the traditional analytic hierarchy method was improved. Based on the extraction rule of general target attribute value, the quality synthetically evaluation model were established.In this paper, launched a study on forest resources individual, groups, communities and ecological economic environment forest resources in the Three Gorges reservoir area in western Hubei, has studied the forest resources spatial structure, function and changes, to guide the forest resources management, protection and rational utilization, realized the forest resources Sustainable Management in the Three Gorges reservoir area in western Hubei to provide a theoretical basis and scientific way.Through the system requirements analysis, system functions analysis and design, database design, system spatial statistics design, the forest resource management and decision-making are based on integration of spatial data and attributes data, and through the combination of attribute data and spatial data, further spatial analysis, Mining hidden behind the information in the data, for the regional forest resource management and decision-making to provide strong technical support.
