Study on environmental protection and evaluation index system of shale gas development in China

The purpose of this study is to explore shale gas conservation evaluation model,to fill the blank in this field and ensure the sustained steady development of shale gas development;This study uses the data access method and the field research method to analyze the current situation of the development of shale gas of China and the United Stated,and details the atmosphere and water pollution problems that shale gas development may lead to,and establishes four first-grade index system and 18second-grade index system of the environmental protection evaluation index system,using the Delphi method and AHP method to determine weight coefficient.Finally,according to the security level corresponding to weight coefficients to judgment the ecological environment security situation of shale gas development,then provide decision reference to whether shale gas development implement or not.
