摘要
我国是世界上岩溶发育最为广泛的国家之一,岩溶分布广、面积大、类型多,岩溶地区河流水资源结构的复杂性、实测资料的匮乏使得相关水文地质参数的获取变得困难,一定程度上制约了岩溶地区工程建设。为了研究水库的多年平均径流量,合理的确定水库规模,文章分析了马坝河流域岩溶水的水动力联系;采用降雨径流以及参证站相关对研究站点(龙塘水文站)径流资料进行插补延长,得到坝址长系列天然来水量系列;并结合水文地质调查成果,验证径流成果的合理性。计算结果标明:龙塘水库径流组成含有外流域古柏河的来水,水库所在流域为非闭合流域,水库所在地区为盈水地区,同时坝址以上实际径流深能与周边相适应,坝址径流结果合理。文章对强岩溶非闭合流域水库天然径流分析具有一定的指导意义。
China has one of the most widely developed karst area all over the world,which is widely distributed with large area and various types.The complexity of structure of water resource in karst area and the lack of measured data are making obtaining hydrogeological parameters very difficult,which restricted engineering constructions in karst region to a certain extent.In order to analyze the average annual runoff of the reservoir and determine the reservoir size reasonably,the hydrodynamic relationship of karst water in Maba River Basin is analyzed.The runoff data of the research station(Longtang Hydrology Station)were interpolated and extended by using rainfall runoff and reference stations,and the long series of natural water intake at the dam site was obtained.Combined with the results of hydrogeological survey,the rationality of runoff results was verified.The calculation results indicate that the runoff composition of Longtang Reservoir contains the inflow from Gubai River in the outer drainage basin,the drainage basin where the reservoir is located is not closed,and the area where the reservoir is located is the area with abundant water.Meanwhile,the actual runoff depth above the dam site can be adapted to the surrounding area,and the runoff result of the dam site is reasonable.This paper has a certain guiding significance for the analysis of natural runoff of reservoirs in strong karst unclosed watershed.
