摘　　要：在分析大庆及周边地区地质、地貌与气候等资料的基础上,根据研究区湿地形成所需的条件,选择地貌类型、是否有地表水分布、地形坡度等八项指标为影响湿地发育的主要因子,采用层次分析法建立了湿地适宜性评价指标体系。利用MapGIS软件平台对指标因子矢量化,运用空间分析功能将各评价因子按照层次分析法所确定的权重进行叠加,计算了湿地适宜性指数,并依据该指数划分了湿地发育的区域,评价结果为该区湿地保护及资源开发提供科学依据。Based on the analysis of the geological,geomorphological and climatic conditions in Daqing and surrounding region,analytic hierarchy process（AHP） was used to establish the evaluating system for suitability of wetlands by selecting 8 indices as main factors which affect the development of wetlands.The suitability index of wetlands was calculated by overlying vector graphics of each index drawn by MapGIS according to their respective weights determined by AHP.The suitable area of wetland development was defined and the evaluation result provided scientific bases for wetland conservation and utilization in study area.
