Eco-sensitivity appraisal and protection regionalization on Zishanhu park baised on GIS

摘要

Appraisal and analysing of eco-sensitivity is an effective and crucial way to determine areas where should establish and protect with emphasis. GIS(Geographic Information System), factor superposition method and analytic hierarchy process are adopted in this thesis. The authors choose five ecological factors which are elevation, slope, aspect, vegetation and hydrology to evaluate Eco-sensitivity of Zishanhu park, therefore, individual divisor analysis graph, sensitivity analysis graph and ecological environment protection division map graph are generated. Studying areas are divided into four degree according to eco-sensitivity, which are the most sensitive area, sensitive area, low sensitivity area and insensitivity area. Three ranks of ecological environmental protecting areas are divided based on researching results and analysis of spatial distribution features of Zishanhu park's Eco-sensitivity. Meanwhile, corresponding conservation measures are formulated, which present scientific basis for coordinating conflicts between developmental construction and ecological protection of parks.
