Abstract
Sustainable ecological and environmental development is the basis of regional development. The sensitivity classification of the ecological environment is the premise of its spatial distribution for land use planning. In this paper, a fuzzy matter-element model and factor-overlay method were employed to analyze the ecological sensitivity in Yicheng City. Four ecological indicators, including soil condition,, water condition,, atmospheric conditions and biodiversity were used to classify the ecological sensitivity. The results were categorized into five ranks: insensitive, slightly sensitive, moderately sensitive, highly sensitive and extremely sensitive zones. The spatial distribution map of environmental sensitivity for land use planning was obtained using GIS (Geographical Information System) techniques. The results illustrated that the extremely sensitive and highly sensitive areas accounted for 14.40% and 30.12% of the total area, respectively, while the moderately sensitive and slightly sensitive areas are 25.99% and 29.49%, respectively. The results provide the theoretical foundation for land use planning by categorizing all kinds of land types in Yicheng City.
Highlights
Eco-environmental sensitivity refers to the degree of sensitivity of an ecosystem to human activity, which reflects the potential for antropogenic ecological imbalances and eco-environmental problems [1]
The insensitive area was 56,722.69 hm2, it accounted for 27.65%, which was mainly distributed in the flat region where hypsography was very mild (Figure 3 and Table 2)
This article applies a fuzzy matter-element model and a GIS vector overlay technique to carry out an ecological sensitivity evaluation and distribution for a small region
Summary
Eco-environmental sensitivity refers to the degree of sensitivity of an ecosystem to human activity, which reflects the potential for antropogenic ecological imbalances and eco-environmental problems [1]. Eco-environmental sensitivity of land use planning is a comprehensive index which serves as a basis for land use planning and eco-environmental management. It includes eco-environmental quality, population load, reasonable degree of land use and the level of economic development. A high sensitivity region was found where eco-environmental problems might occur due to human activities [4]. Using GIS, some scholars have conducted evaluations on the sensitivity of water and soil erosion, land degeneration, desertification and classified the regional land use types; these results provided the scientific basis for ecological construction and sustainable development in Jilin
