Research On The Planning Of Water-system In Urban Wetland In The Perspective Of Ecologism

Wetland is one of the three most important ecosystems on earth, along with forest ecosystems and marine ecosystem. Before 1980s, development on wetland resources was almost predatory, which caused great damages on wetlands. So when it came to 1980s, humans began to aware of importance of protecting wetlands. Nowadays, constructing city wetland parks is a effective way to protect and expand wetland areas and so it has developed rapidly. Water is the soul of Urban Wetland Park, and the circulation of water system is the basis of the normal operation of the parks.Based on ecological theory,this artical takes the water systems in city wetland parks as resear ch object,studies correlative theories and papers both at home and abroad.Using literature survey, case studies, field research and computer simulation methods,it explores the framework of water s ystems planning in city wetland parks,taking landscape ecology,ecological restoration and hydrolo gic connectivity theory as basis. Also,the artical practice it in the programming of Beijing Daxing Changziying wetland park,trying to improve and perfect the theory of planning water systems in ci ty wetland parks in our country by means of applying theory to practice.
