The Study on The Ecological Road Evaluating System of PoyangLake Eco-economic Region Based on ArcGIS Technology
Abstract
The establishment of PoyangLake Eco-economic Region make the economic development in Jiangxi enter into a new era, but it also makes higher requirement on harmonious development of road construction in PoyangLake plicated engineering geological conditions, the unbalanced distribution of present roads resources, the different ecological conditions among different areas in PoyangLake region, in the premise of investing the same resources in the construction of roads around PoyangLake region, how to make the roads develop in the most optimal way, the road resources can be utilized fully, and not cause serious damage to the surrouding ecological environment are the great problems that the future road planning and development in PoyangLake region must confront with.
Based on the reasonable road arrangement and development, directing at engineering geology, roads and ecological conditions, using some related theories such as engineering geology, road ecology, the paper studies the development of the roads around PoyangLake bining with the study of ecological environment protection.
First,we establishes the ecological evaluating system regarding to engineering geological conditions, the conditions of distribution and the ecological conditions on the basis of collecting various documents and materials about the region, visit some related apartment to get its statistical data and future planning materials, field sampling and studying the region. Second, we set three evaluation index of the evaluation system on the basis of analyzing the data. Then by quantification of the evaluation, the analytic hierarchy process( AHP) and prehensive evaluation method are applied to calculate various evaluation index to get the score of geological conditions around PoyangLake region, of road conditions, of the carrying-capacity of an ecosystem.
