丽江市水资源环境现状与应急地下水源地研究

Study on the Status of Water Resources Environment and Emergency-Type Groundwater Source Fields of Lijiang City in Yunnan

水资源是丽江世界文化遗产地的灵魂和城市社会经济发展的基础。目前丽江面临着水污染加剧、景观水质和水量不足、水资源利用率低等问题。丽江盆地水资源量可以满足丽江城市近期和中期发展需要,对远期保障率不高。在城市环境水文地质调查的基础上,提出盆地边缘的岩溶大泉及盆地中部冰水堆积的砂砾石层中的孔隙潜水及承压水可作为丽江城市应急地下水源地。

Water resources are the soul of the world cultural heritage in Lijiang and they are also the base of the development of social economy. At present, Lijiang is confronted with many problems, such aS the severe water pollution, the lack of water quality and quantity, the low utilization ratio and so on. The water resources quantity in Lijiang basin can meet the demand of the recent and metaphase development of Lijiang city, but it is not sure for the future. Based on the geological survey of city environmental hydrology, the article puts forward that the karst big spring around the basin and the pore water and confined water between the gravel layers in the middle of the basin can supply for the emergency - type groundwater source fields.
