天府新区夹关组地下水富集规律及开发利用认识
发布时间：2018-09-13 12:06
【摘要】：成都市天府新区的快速发展对区内地下水需求急剧增大,保护好地下水资源,合理开发是可持续发展的重要命题。在区内地下水资源贫乏的大环境下,对具有开采意义的夹关组裂隙孔隙层间水的含水层结构及地下水富集规律进行分析,圈定富水区块6.2 km2,计算地下水可开采量为6 800 m3/d,可供约4.25万城市居民生活用水。水量虽不能满足城市发展需要,但作为分散性的集中开采,一定程度上可以缓解区内地下水贫乏与其开采需求大的供需矛盾。最后,提出了合理开发利用的建议以及存在的问题。
[Abstract]:The rapid development of Tianfu New District in Chengdu has greatly increased the demand for groundwater in this area. It is an important proposition for sustainable development to protect groundwater resources and develop them reasonably. In the environment of poor groundwater resources in this area, the aquifer structure and the law of groundwater enrichment of the pore layer of fracture in Jiaguan formation, which has the significance of mining, are analyzed. The 6. 2 km2, calculation of groundwater exploitation in the delineated water rich block is 6 800 m3 / d and can be used for the domestic use of about 42500 urban residents. Although the quantity of water can not meet the needs of urban development, as a decentralized centralized exploitation, it can alleviate the contradiction between the shortage of groundwater and the large demand for exploitation. Finally, the suggestion of reasonable development and utilization and the existing problems are put forward.
