| 中文摘要:云南泸西岩溶断陷盆地水资源丰富, 但水资源时空分布极为不均, 水资源利用率低。盆地地貌具有水平分区明显, 垂向分级清楚的特点, 盆底沉积平坝区是南盘江流域的局部上层排泄基准, 其间残存和恢复重建的湿地具有调节和净化水的功能, 且高程接近于供水需求区带。因此, 分析和构建地表水-地下水联合调度的水资源循环利用方案, 可有效提高水资源的利用率。通过研究泸西典型岩溶断陷盆地流域的地质环境条件与水循环系统, 查明其水资源赋存状况、可开发资源量和开发利用现状, 以地球系统科学为指导, 应用系统分析、水文及水文地质分析评价等方法, 结合黄草洲、平海子湿地生态的恢复重建和涵养, 提出岩溶断陷盆地水资源的循环利用方案, 一是黄草洲湿地生态的恢复重建和涵养, 采用物理、生物、化学措施进行水处理净化, 泵站提水供应生产、农业灌溉循环利用, 形成生态恢复工程-资源循环利用的方案; 二是工农隧道调蓄时空不均的内涝, 引自平海子水库, 旱季供灌溉、雨季供发电; 有效提高岩溶断陷盆地水资源的循环利用水平。云南岩溶断陷盆地众多, 可在盆地下游建湿地或净化池, 处理生活污水和地表水, 提水输送、隧道引水调蓄内涝、抗旱, 解决时空不均的水资源利用。该方案可操作性强, 在断陷盆地推广运用前景好。 |

| The Water Circulation System and Water Resources Recycling Plan of the Luxi Karst Fault-depression Basin in Yunnan |

| Abstract:The Luxi karst fault-depression basin in Yunnan is rich in water resources, but the distribution of water resources is extremely uneven in time and space, and the utilization rate of water resources is low. The topography of the basin is characterized by obvious horizontal division and clear vertical classification. And the basin-bottom sedimentary flat dam area is the benchmark for local upper drainage in the Nanpan River basin. The remaining and restored wetland has the function of regulating and purifying water, and its elevation is close to the water supply demand zone. Therefore, analyzing and constructing a water resource recycling plan for the joint dispatch of surface water and groundwater can effectively improve the utilization rate of water resources. By studying the geological environment conditions and water circulation system of the typical karst fault-depression basin in Luxi, researchers can find out the occurrence of water resources, the amount of exploitable resources, and the current status of development and utilization. Guided by earth system science, applying such methods as system analysis, hydrology and hydrogeological analysis and evaluation, and combined with the restoration, reconstruction and conservation of the Huangcaozhou and Pinghaizi wetlands, the authors propose a plan for the recycling of water resources in the karst fault-depression basin. The first is the restoration, reconstruction and conservation of the Huangcaozhou wetland ecology, using physical, biological, and chemical measures for water treatment and purification, pumping water for production, and agricultural irrigation recycling, forming an ecological restoration project—resource recycling plan; the second is to use the Gongnong tunnel to adjust and store the uneven waterlogging in time and space, drawn from the Pinghaizi reservoir, for irrigation in the dry season and power generation in the rainy season, thus effectively improving the level of water recycling in the karst fault-depression basin. There are many karst fault-depression basins in Yunnan, and hence wetlands or purification ponds can be built in the lower reaches of the basin to treat domestic sewage and surface water, pump and transport water, and use tunnels to divert and store waterlogging for drought relief, so as to solve the problem of uneven water resource utilization in time and space. This plan has strong operability and good prospects for popularization and application in fault-depression basins. |
