Peer review declaration

All papers published in this volume of IOP Conference Series: Earth and Environmental Science have been peer reviewed through processes administered by the Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing. • Type of peer review: Double-blind: While receiving a new submission, we/our editors firstly check the scope of it whether suitable for our conference. If not, it will be rejected directly. If yes, it will be sent out to check plagiarism and then peer review. We choose 2 reviewers for each of the submission and after getting the two reviews, we conclude a final result for the paper. Once the two reviews show totally different attitudes, we will find another reviewer for it until we get the final result. • Conference submission management system: Through our Email system. The Email address used as the management system is iccecn@163.com, which is in charge by Guangyuan Li. • Number of submissions received: 646 • Number of submissions sent for review: 575 (71 out of scope papers rejected directly after receiving) • Number of submissions accepted: 279 • Acceptance Rate (Number of Submissions Accepted / Number of Submissions Received X 100): 43% • Average number of reviews per paper: 2-3 • Total number of reviewers involved: about 180 • Any additional info on review process: • Contact person for queries: Hubei Zhongke Institute of Geology and Environment Technology Cathy Wang esce_2018@163.com
