Taking surface runoff of Coastal Highway in Liaoning Province as research object, this paper analyzed water quality characteristics of runoff and flow rules of pollutants. It proposed using constructed wetland treatment technique in the drainage system from the perspective of effectively removing major pollutants. Using the constructed wetland k - C * model and relevant experience, parameters of constructed wetland can be obtained. The basic model is as follows: constructed wetland lies in two sides of the road, and surface runoff sewage is collected and treated separately with 1 km road section as the collecton unit. The wetand area in one side is 191. 6 m2, average water depth is 0. 5 m, wetland width is 8 m, and wetland length is 24 m. [ABSTRACT FROM AUTHOR]

According to the needs of Liaoning province marine economic operation monitoring and evaluation system for capacity building in this paper, it proposes the concept of marine economy operation monitoring and evaluation system, and introduces the system construction content and its architecture, and discusses the key issues on the monitoring index system, evaluation index system, mechanism construction and system implementation. It will help to improve the Liaoning marine economic statistical informatization level and promote the innovation of marine economy in Liaoning, and expect to provide reference for the system construction of other coastal provinces' provincial marine economy operation monitoring and evaluation system.
