关中盆地地热资源丰富，长期自发或粗放经营已引起地下热水水位持续下降，压降漏斗明显形成，严重破坏了地热资源的可再生能力，资源的可持续性逐渐降低，主要原因在于地热资源梯级利用的力度和广度不够，尾水回注量与开采量相差甚远。目前回注技术方面已经有所突破，但是针对不同区域工艺性和经济性研究仍较有待于进一步加深。如何实现地热资源的可持续和高效利用仍然是地热资源开发需要解决的重要问题。

In Guanzhong Basin, geothermal resources is rich, and long term spontaneous or ex-tensive management had caused a continuous decline in the water level of underground geother-mal water, therefore, the pressure drop funnel was formed, which seriously damaged the re-newable ability of the geothermal resources. The sustainability of resources is gradually reduced, and the main reason lies in that the intensity and breadth of the cascade utilization of geother-mal resources were not enough, and the reinjection quantity of geothermal utilized water was far apart from its yield. At present, the reinjection technology has a breakthrough, but the research on the technology and economy of different regions is still to be further deepened. How to realize the sustainable and efficient utilization of geothermal resources still is an important problem that need to be solved in the development of geothermal resources.
