摘要
生态环境作为区域可持续发展的制约因素和重要基础至关重要,研究对区域的生态环境敏感性进行评价意义重大。研究综合选取了地形地貌、水环境、土壤、坡度等评价因子,采用GIS技术以生态学视角建立综合评价模型对宁安市的区域生态环境敏感性进行了评价。结果显示:宁安市区域的生态环境可分为极敏感区、高度敏感区、中度敏感区、轻度敏感区和不敏感区5个等级。研究进一步明确了宁安市生态环境敏感性的空间分布特征,为宁安市的生态环境保护和区域可持续发展的政策制定提供了一定参考。
Ecological environment is very important as a restricting factor and important foundation of regional sustainable development. The evaluation factors such as topography, land form, water environment, soil and slope were selected, and a comprehensive evaluation model was established by using GIS technology from the perspective of ecology to evaluate the regional ecological environment sensitivity of Ning’an city. The results showed that the ecological environment in Ning’an city can be divided into five levels;extremely sensitive area, highly sensitive area, moderately sensitive area, mildly sensitive area and non-sensitive area. The study further clarified the spatial distribution characteristics of the eco-environmental sensitivity of Ning’an city, and provided certain reference for the fonnulation of the eco-environmental protection and regional sustainable development policies of Ning’an city.
