The characteristics and key design points of constructed wetland under the ecological principles were explored, taking the Jingyue Lake in Zhongxiang City, Hubei Province for example, treatment processes were designed for different infl ow waters on the basis of site analysis to facilitate the water environment control and ecological landscape construction, ecological theories were applied to explore functional layouts and landscape designs of wetland, to build a favorable ecological environment of urban wetland and design outstanding wetland ecological landscapes.展开更多

The present malaise is assessed, as regards inefficiencies, non-suitability, non-sustainability, enhancing factors of environmental degradation, and potentially destructive consequences of current land-use alteration. Desired situations and goals are considered, and means are proposed for bridging the gap between the present malaise and a desired situation, based on five key approaches developed by the authors. Specific examples of regional approaches are presented. Guidelines and operational measures for sound regional planning the authors have employed in similar circumstances are recommended.展开更多

Local nurseries total 6.40 km 2 , accounting for 5.1% of total constructed land area in the prefecture, and only 0.02% of the total land area in the prefecture. Application of local plant species in landscape engineering and green coverage ratio lags far behind the indexes of Chinese livable city and indexes of relieving urban heat island effect. By making proper policies and measures, seedling production can be promoted, rare and endanged wild plant species should be fully used to construct garden city, control PM2.5 and protect the living environment.展开更多
