COMPREHENSIVE EVALUATION AND SUGGESTIONS FOR DEVELOPMENT AND UTILIZATION OF HYDROTHERMAL RESOURCES IN HANGZHOU-JIAXING-HUZHOU PLAIN

The comprehensive evaluation of hydrothermal resources in Hangzhou-Jiaxing-Huzhou region shows that the geothermal reserves is 439.18×10¹⁴ kJ, with the geothermal fluid storage of 212.22×10⁸ m³, the exploitable geothermal fluid of 16 864.8×10⁴ m³/a, and the exploitable heat of 2 366.88×10¹⁰ kJ/a, which can be used for convalescent tour, geothermal heating and aquaculture. It is suggested that the local authorities should pay equal attention to the protection of geothermal resources in the process of development and utilization to achieve scientific planning, rational exploitation and green sustainable development. Besides, the geothermal resources can be combined with the characteristic agriculture and construction of geological cultural village to form a cascade comprehensive utilization mode, combined with the abundant shallow geothermal energy resources to form a deep-shallow combination utilization mode, and combined with clean energy technologies such as heat pump, solar energy and air energy to form a "geothermal+" compound development mode.
