Scientific development, rational utilization of deep geothermal resource —Strategic thought about development of sustainable clean energy

China is a country with many geothermal resources, there are rich geothermal resources which should be developed in many areas, although it has certain difficulty about exploration, development and utilization of deep geothermal resources, scientific development and rational utilization of deep geothermal resources has profound strategic significance. Systemic and further exploration and strategic thinking about important related problems of development of deep geotherm, the sustainable clean energy, are carried out. Furthermore, countermeasures and suggestions are presented in this paper: Based on scientifical planning, deep geothermal resources should be developed designedly and reasonably to keep deep geothermal resources protracted nature, stable and sustainable, moreover, management method of investment fund should be introduced to develope geothermal resource; Heat field distribution law and heat storge theory and other related field should be investigated deeply; It's necessary to establish a series of national united automated information management system and dynamic monitoring system of geothermal resource.
