Abstract:
Abstract: 【Objective】Scientifically evaluate the ecological sensitivity of the water network areas in the south of Jiangsu Province so that the rural natural landscape can be developed in a sustainable manner, and its ecological stability can be maintained.【Method】Taihu Lake East Village was chosen as the study area. This study used ArcGIS 10.0 to evaluate its ecological sensitivity using data collated from documents and by consulting experts. Seven evaluation indicators were used, that included topography, land use type, traffic accessibility, grade of slope, direction of slope, geological hazard, and distance from water. After analysis of the ecological conditions, spatial situations, and landscape features in the study area, we obtained the regional ecological sensitivity maps showing different grades. 【Result】 We found that the most important indicator affecting the ecological environment of the East Village was the land use type. The effects of geological hazard and distance from water were less. Because of the relatively flat terrain and low traffic density, the influence of slope and aspect was normal, and the influence of traffic accessibility and terrain was weak. 【Conclusion】The ecological sensitivity map, which is simulated by weighted superposition, shows that the area near the water within the East Village, the area prone to geological disasters, and the area with steep slopes are the most sensitive to landscape level disturbances, while other areas that are close to the village and with a flat terrain at the foot of the mountains are weak to ecological sensitivity. These results can provide guidelines for decision-making for the conservation planning of the East Village as well as construction in this beautiful rural area.
