Zhang J, Wang K, Chen X, Zhu W - Int J Environ Res Public Health (2011)

Bottom Line: The results were categorized into five ranks: insensitive, slightly sensitive, moderately sensitive, highly sensitive and extremely sensitive zones.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.

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.

Mentions: Soil conditions are controlled by factors including soil and water loss, soil quality, land use/land cover, influence of the intensity of land use, etc. Soil quality is crucial for soil conditions and it varies with landforms and the environment. From the spatial distribution of soil-erosion sensitivity (Figure 3), it was deduced that the extremely sensitive area covered 20,452.99 hm2 and accounted for 9.97% of the total area in Yicheng City, corresponding mainly in the high mountainous region where the landform was very complicated. The highly sensitive area was 28,535.72 hm2 and accounted for 13.91%, which was distributed in low mountains and high hills region. The moderately sensitive area was 38,218.58 hm2 and accounted for 18.63%, which was distributed in low valley regions. The slightly sensitive area was 61,215.37 hm2, accounted for 13.91%, and was distributed in low valleys and flat regions. 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).
