- Abstract:
-
Regional ecological sensitivity analysis is an effective tool for making regional social and economic development policies and environmental management. Taking Renhuai City of Guizhou Province as the research area, sensibility and its spatial distribution were studied in views of the sensitivities to land use, elevation, slope, water system, geological disasters under support of GIS technologies. Single and comprehensive element sensitivity assessment is used in the study. Results show that the extreme sensitive area accounts for 1.43% of the total area, which mainly lies in high altitude mountain.The sensitive area accounts for 17.76%, which distributes in valley and foothills.The low sensitive area accounts for 57.41%, which distributes in low mountain.The insensitive area accounts for 23.40%, which distributes in urban areas. By combining with the result of eco-environmental sensitivity assessment, countermeasures for eco-environmental construction and protection of each of the areas are proposed and a basis for government making policy is provided.
