【摘要】：成都市天府新區(qū)的快速發(fā)展對(duì)區(qū)內(nèi)地下水需求急劇增大,保護(hù)好地下水資源,合理開發(fā)是可持續(xù)發(fā)展的重要命題。在區(qū)內(nèi)地下水資源貧乏的大環(huán)境下,對(duì)具有開采意義的夾關(guān)組裂隙孔隙層間水的含水層結(jié)構(gòu)及地下水富集規(guī)律進(jìn)行分析,圈定富水區(qū)塊6.2 km2,計(jì)算地下水可開采量為6 800 m3/d,可供約4.25萬(wàn)城市居民生活用水。水量雖不能滿足城市發(fā)展需要,但作為分散性的集中開采,一定程度上可以緩解區(qū)內(nèi)地下水貧乏與其開采需求大的供需矛盾。最后,提出了合理開發(fā)利用的建議以及存在的問(wèn)題。
[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.
