Analysis on the conditions of forming reservoirs from surface dissolution basins and underground karst: An example of the Nongyan reservoir

摘要: 水资源已成为人类社会及经济发展的重要制约因素，国内外都在积极探索不同气候、不同地质条件下水资源的合理开发利用。受地下岩溶发育及气候影响，岩溶地区的地表及地下水资源在时间、空间上分布极不均匀，旱涝并存，通常以单一拦蓄地表水或直接抽取地下水来应对，存在较大局限性。文章在总结分析前人的研究成果上，结合弄岩水库，利用水文系列资料进行相关分析，找出地表水与地下水之间的变量关系及相应可开采水资源量；查明地下岩溶蓄水条件，在岩溶通道设置地下拦蓄工程，实现地表水与地下水联合开发，并利用地表及与地下岩溶水库的调蓄功能均衡供水，有效解决旱涝问题，水资源得以最大化合理利用。Abstract: There are six methods to study surface water-groundwater interaction as well as the formation of reservoir from the interaction, which are the analytical method, numerical modeling, hydrogeochemistry, intelligent method, 3S method and the method of hydrogeological survey, exploration and correlation analysis. Multiple methods are usually applied simultaneously according to the purposes of projects. The former five ones are mainly applied to theoretical research, and the last method is widely used for development and application purpose. On the basis of summarizing previous studies and taking the Nong Yan Reservoir as an example, this paper aims to clarify the scope of karst development and associated hydrological units, taking into account of the development degree, elevation, direction and geometric shape of the inner space of rock mass, as well as the development rate of karst surface at different elevations by means of hydrogeological investigation, drilling and geophysics. Meanwhile a mathematical model of underground reservoir capacity was established, so as to calculate the underground karst reservoir capacity accurately. Besides, through correlation analysis, hydrologic data was utilized to reveal the variable relationship between surface water and groundwater, and their laws and hydrogeological parameters, so as to obtain the annual exploitable amount of surface water and groundwater resources.
