摘　　要：灵江流域是浙江重要的经济活动区。为更准确计算灵江流域山丘区地下水资源量,本文采用基流分割法、最小月流量法、枯季径流模数法对研究区2000-2019年地下水资源量进行计算。结果表明,灵江流域山丘区地下水资源量用基流分割计算结果为13.73亿m^(3)/a,最小月流量计算结果为12.27亿m^(3)/a,枯季径流模数法计算结果为10.14亿m^(3)/a。评价结果与台州市第三次水资源调查评价结果对比表明,基流分割法更适宜灵江流域山丘区地下水资源量计算。研究结果能为该区域生态环境保护及共同富裕示范区建设提供基础数据支撑。The Lingjiang River Basin is an important economic activity area in Zhejiang.To more accurately estimate the groundwater resources in the hilly regions of the Lingjiang River Basin,this study employs the baseflow separation method,the minimum monthly flow method,and the dry season runoff modulus method to calculate groundwater resources from 2000 to 2019.The results indicate that the groundwater resource estimate for the hilly area of the Lingjiang River Basin using the baseflow separation method is 1.373 billion m^(3)/year,the minimum monthly flow method yields 1.227 billion m^(3)/year,and the dry season runoff modulus method results in 1.014 billion m^(3)/year.The evaluation results align with those from the third water resource survey and assessment in Taizhou,suggesting that the baseflow separation method is more suitable for estimating groundwater resources in the hilly areas of the Lingjiang River Basin.These findings provide essential data support for ecological environment protection and the construction of a demonstration area for common prosperity in the region.
