西南诸河地下水资源量调查评价分析

根据地下水资源调查评价方法的基本原理,结合地形、地貌、水文地质条件以及水资源流域（水系）分区,对西南诸河6个二级水资源综合规划分区、14个三级水资源综合规划分区、若干个地下水均衡计算区,以1980～2000年为代表的近期下垫面条件下的多年平均年地下水资源量进行评价.在各均衡计算区地下水资源量评价成果的基础上,确定各水资源分区的地下水资源量,同时对西南诸河地下水资源量分布及特征作了全面分析;为西南诸河水生态良性循环、地下水资源量开发利用提供了详实的基础资料.

Investigation and evaluation on underground water resources quantity of the river basins in south-western China

According to basic principle of water resources investigation and evaluation method and lanforms,hydrological and geological condition,and in the combination of basin division(river system)of water resources,the underground water resources quantity of 6 grade II water comprehensive planning division areas, 14 grade III water comprehensive planning division areas,some underground water balance areas in the south-western China are evaluated under representative underlying surface in recent years from 1980 to 2000.On the basis of underground water resources quantity evaluation in the balance calculation areas,the underground water resources quantity in the water resources division areas are determined.The overall analysis is carried out for underground water resources quantity distribution and features of basins in south-western China,providing a sound foundation for favorable cycle of water ecology and underground water resources development and utilization of the river basins in south-western China.
