摘 要:在科学把握地下水系统恢复力概念和内涵的基础上,从地下水含水层特性、补给条件、区域特点、技术水平和社会经济5个方面选取26个典型指标构建了下辽河平原地下水系统恢复力指标体系,并对指标的评价标准进行划分,采用层次分析法和GIS空间叠加技术对其地下水系统恢复力进行评价,结果表明:新民-辽中平原、柳河平原和南部滨海平原地下水系统恢复力较强;辽河冲积扇、浑河冲积扇、太子河冲积扇及西部扇前平原的部分地区恢复力处于中等水平;大小凌河冲积扇、羊肠河冲积扇、黑鱼沟河冲积扇、海城河冲积扇和北部的阜新、铁岭等地恢复力最弱,有待进一步提高。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.
