Evaluation of the Current Situation and Planning of the Greenspace System in Huaibei City Using GIS Based Network Analysis

In rapid urbanization, how to construct the rational landscape network have great significances in keeping the urban ecosystem healthy and improving the quantity and quality of the current greenspace system. The basic research materials are urban current land use, greenspace current situation, green space system planning and satellite images of Huaibei in 2006. Supported by GIS , the research chooses the main urban area in Huaibei with an area greater than 10 hm² of afforestation space as the node, according to the analytic approach of the network, the research establishes the idealized ecological networks, through index alpha , index beta , index gamma, compare their network structure integrality, choose the best network. The paper analyzes with the landscape analysis software Fragstats, uses the method of landscape pattern analytical. It selects the indexes of many kinds of analysis landscape for use, analyzes the systematic current situation of greenspace, greenspace system planning and the idealized ecological network scheme of Huaibei in terms of landscape ecology. It is an effective route to evaluate and improve the greenspace system planning with the ecological network analysis combines with the pattern analysis of the landscape, and the ecological network scheme planning to be made on the greenspace system planning can further improve main quantity and quality with systematic current greenspace of urban area.
