GIS在采煤沉陷区生态价值评价中的应用

以淮南市在采煤沉陷区生态治理规划中对规划区的生态价值评价为例,探讨了运用GIS技术和多源信息复合原理对规划区进行生态要素单因子评价和生态价值综合评价,选取评价因子包括地形因子、生态基质因子、植被因子及水环境保护因子。采用遥感与地理信息系统相结合的技术,建立与评价相关的基于GIS的基础数据平台,运用GIS的空间分析功能对规划区的生态价值进行分析和评估。通过对规划区各类生态因子的评价,深入了解规划区内生态价值的特征与空间分布,提取重要生态节点;为挖掘规划区生态建设潜力,实施生态治理和建设提供依据。

Research on GIS Application in Mining Subsidence Area Ecological Value Evaluation

In this paper,we discussed the use of GIS technology and the principle of multi-source information on complex ecological elements of the planning area and the ecological value of single factor assessment evaluation.Ecological Management and Planning of coal mining subsidence on the evaluation of the ecological value of planning area in Huainan,as this model,we selected the evaluation factors,including to-pography,ecological matrix factors,vegetation and water environmental protection factor.Using the combination technologies of Remote Sensing and Geographic Information System to establish the base data platform based on GIS,analyzed and evaluated the ecological value of the planning area using GIS spatial analysis function.By evaluating various ecological factors in planning area,and thorough understanding the characteristics and spatial distribution of ecological value,we could extract the important ecological nodes in order to provide the basis for finding the potential of ecological construction planning area and the implementation of ecological manage-ment and construction.
