The Ecological Sensibility Analyzing Of Zhaichangshan Forest Park In Huidong County Based On GIS

As the place of Eco-tourism around the city, Forest Park is not only the organic part of natural matrix, but also the important part of promoting touristic economic growth. In that case, considering the touristic benefit and how to use resources mostly is the main purpose of Forest Park plannings. As the scientific and objective analyzing methods, the Ecological Sensibility Analyzing is basic of abilities about handling complex messages in GIS and considering the influence of comprehensive factors. It’s the vital guideline for Eco-planning of Forest Park.Forest Park, being dual attributes, is a tourist attraction place where depend on the natural resources deeply, which is confirmed by analyzing papers nearly years. The Ecological Sensibility Analyzing is developed from aiming at the single ecological-problem to apply for planning city zones or landscape spaces.The theory system of Forest Park Ecological Sensibility Analyzing is built, including analyzing methods, targets, contents, units and index systems. The detailed study about analyzing methods and index systems is available. A unified index system is built,consisting of five standard-level factors:vegetation, hydrology, topography, atmosphere, human-behaviors, and eleven objective-level factors:fractional vegetation cover, vegetation-type, water-type, water-buffer area, elevation, slope, aspect, PM10, land-use type, and road-buffer area.Applying the theory system to Zhaichangshan Forest Park with GIS. Through the Ecological Sensibility Analyzing, the distributional image and the classified sensibility image of every single factor are made. Basic of using AHP to calculate the weight of every factor and using GIS to overlying all the factors with their weight, the Ecological Sensibility Analyzing of the park is made, with the entirety value range from 1.582 to 4.415. From this, the ecological sensibility of Zhaichangshan Forest Park is divided into five levels:low sensibility, lower sensibility, medium sensibility, higher sensibility, and high sensibility. The areas of each part are 123.4hm2、303.32hm2、368.48hm2、254.76hm、and 101.41 hm2, and the percentages are 10.71%、26.34%、32.00%、22.13% and 8.82%. According to the results, there levels of protecting areas are divided and the suggestion of each part are given. The areas of each part are 354.45hm2,673.52hm2,123.4hm2, and the percentages are 30.79%, 58.5% and 10.71%.
