在科学理解地下水系统恢复能力概念和含义的基础上，从地下水含水层特征、供给条件、区域特征、技术水平和社会经济等5个方面选取26个典型指标，建立了辽河下游平原地下水系统恢复能力评价体系。对各指标的评价标准进行了分类。采用层次分析法和GIS空间叠加技术对地下水系统的恢复能力进行了评价。结果表明：新民-辽中平原、六河平原和南部滨海平原的恢复能力最强，辽河冲积扇、浑河冲积扇、太子河冲积扇和西部平原的恢复能力为中等，北部陵河冲积扇、长长江冲积扇、黑峪沟河冲积扇、海城河冲积扇和阜新、铁岭冲积扇的恢复能力最弱，有待进一步提高。研究成果对辽河下游平原水资源的可持续利用具有重要意义。
Based on the scientific understanding of the concept and meaning of the recovery capacity of groundwater system,an evaluation system for the lower Liaohe River Plain was established by selecting twenty-six typical indexes from five aspects of characteristics of groundwater aquifer,supply conditions,regional characteristics,technical level and social economy.The evaluation standards for the indexes were classified into different categories.The analytic hierarchy process and the GIS space stacking technique were employed to evaluate the recovery capacity of groundwater system.The results show that the recovery capacity of Xinmin-Liaozhong plain,Liuhe plain and the southern coastal plain is the strongest,that of Liaohe alluvial fan,Hunhe alluvial fan,Taizihe alluvial fan and the western plain is intermediate,and that of Linghe alluvial fans,Yangchang River alluvial fan,Heiyugou River alluvial fan,Haicheng River alluvial fan and Fuxin and Tieling in the northern area is the weakest and needs to be further improved.The research achievements are significant for the sustainable exploitation of water resources in the lower Liaohe River Plain.
