摘　　要：在村级土地利用规划过程中进行生态功能适宜性评价,以了解农村生态质量状况、明确农村生态功能适宜程度及空间分布,为村级土地利用规划中土地利用方向的确定和空间布局的划分提供科学的生态适宜依据,从而更好地协调农村发展建设和生态环境保护的关系有着至关重要的作用。以岩南村为例,开展了农村生态功能适宜性评价及应用研究。以高分辨率航空影像为数据源,从地形条件、土壤资源、生物资源、水资源、人类干扰5个方面建立了评价指标体系;利用组合赋权法确定各评价因子的权重值,构建了生态功能适宜性评价模型;以栅格为评价单元,在GIS支持下,对岩南村进行生态功能适宜性评价。并根据评价结果划分了生态功能适宜等级,制定了分区管制措施,提出了土地利用建议,旨在为岩南村土地利用规划提供指导。Abstract.. Ecological function suitability assessment in village land use planning is benefit to identifying the ecological quality status,ecological function suitability and its spatial distribution. It is of vital importance in providing ecology basis for determining the direction of land use and spatial distribution in rural land use planning,and then harmonizing rural construction with ecological environment protection. Taken Yannan village as an example,this study carried out the rural ecological function suitability assessment and its ap- plication research. Firstly, the evaluation index system was established from five angles as terrain condi- tions, soil resources, biological resources, water resources, and human interference, with high resolution avi- ation remote sensing image as data source. Then, synthetic assessment model of ecological function suitabil- ity was set up by using combination weighting method, and the ecological function suitability in Yannan vil- lage was assessed with GIRD as evaluation unit in the support of GIS. At last,based on assessment result, Yannan village was divided into 4 ecological function zones with their corresponding measures and land use advices, which will provide guidance for land use planning in Yannan village.
