摘    要:本文对滇东断陷盆地南洞岩溶地下水系统各地下河的水文动态特征进行了分析,推断了南洞岩溶地下水系统的结构特征.根据岩性构造、地下河发育以及补径排关系,将其划分为四个子系统.分别采用降雨入渗系数法和径流模数法对南洞岩溶地下水系统的天然资源量进行计算,计算结果分别为35610.7万m3/a和33460.2万m3/a.用枯季径流模数法对南洞岩溶地下水系统的可采资源量进行了计算,计算结果为23407.3万m3/a,其可开采资源量巨大.南洞地下河在没有天然补给量的情况下,120天消耗的调蓄量为4503.3万m3,南洞地下河日允许开采资源量为49.4万m3/d.二号暗河建库蓄水条件下库区上游的日允许开采量为75.9万m3/d,蓄水库容来源于工程设计,资源保证程度高.本次研究可为南洞岩溶地下水资源的开发利用和调配提供科学依据.

关 键 词:南洞地下河  岩溶地下水系统  水文动态特征  水资源评价  开发利用

Abstract:In this paper, the authors analyzed underground river hydrological dynamic characteristics of the Nandong karst water system in east Yunnan faulted basin and inferred the structure features of the Nandong karst water system. This system can be divided into four subsystems according to the lithological structure, the development of underground rivers, and the relationship between fill paths and rows. The rainfall infiltration coefficient method and the runoff modulus method were used to calculate the natural water resources of the Nandong karst groundwater system. The calculation results were 356 107 000 million m3/a and 33 602 200 m3/a, respectively. The dry season runoff modulus method was used to calculate the recoverable resources of the Nandong karst groundwater system. The calculation result was 234 073 000 m3/a, and the recoverable resources were huge. Under the condition that the natural supply of the Nandong Underground River was cut off, the adjusted storage capacity consumed in 120 days was 45 033 000 m3, and the daily allowable mining resources of the Nandong Underground River were 494 000 m3/d. Under the condition of impoundment of No. 2 underground river, the daily allowable mining volume in the upper reaches of the reservoir area was 759 000 m3/d. The storage capacity comes from engineering design, and the degree of resource assurance was high. This study can provide a scientific basis for the development, utilization and deployment of Nandong karst groundwater resources.
Keywords:Nandong underground river  karst water system  hydrological dynamic characteristics  water resources evaluation  development and utilization
