Eco-Sensitivity Evaluation and Analysis of Hunan Martyr Park Based on GIS

Using geographic information systems, factor superposition method and AHP, this paper evaluated and analyzed the ecological sensitivity of Hunan Martyr Park from the five ecological factors of elevation, slope, aspect, water distribution and buffer area of water. Hunan Martyr Park has been divided into four grades according to its sensitive degree: high-sensitive area, sensitive area, weak-sensitive area and non-sensitive area. Results show that the high-sensitive area and sensitive area take up 67% of the whole area; Hunan Martyr Park is the park with high ecological sensitivity. To coordinate the contradiction between park development and its eco-environment protection, this paper attempts to put forward the corresponding protection measures so as to provide scientific basis for the eco-environment protection, rational distribution and development plan in Hunan Martyr Park.
