Based on the connotation of high-quality development of water parks,this study established an evaluation system from distinctive water conservancy characteristics,excellent ecological environment,strong cultural atmosphere,strong development momentum,safe and efficient management,and significant comprehensive benefits,including 23 main contents and 52 evaluation indicators.Delphi method was used to score,and the evaluation results were divided into 3 levels,thus forming the evaluation system of high-quality development of water parks.This evaluation system has been preliminarily applied to the collection and selection of typical cases of the first national high-quality development of water parks.A total of 30 typical cases of high-quality development of water parks in China were collected and selected,and the first batch of 10 benchmark scenic spots were announced for key recommendation,and considerable application results have been achieved. 展开更多
