Study On The Design Plan Of Reservoir Watershed Wetland Park

With the development of the times, as one of the important wetlands, the function of the reservoir watershed wetland is no longer limited to flood water storage and regulation of river runoff. People attach importance to ecological function as the restoration of wetland ecosystem and water purification, and social function as leisure and tourism gradually. However, over exploitation caused the damage of wetland resources. It also brought a series of problems, such as the destruction of wetland ecological system and the atrophy of wetland area. These problems has not only caused the reservoir watershed wetland been destroyed, but also the ecological function and social function of wetland can not fully play. It become an urgent problem for us to protect the reservoir watershed wetland and its ecological and social function. Reservoir watershed wetlandpark is the wetland area to be protected, it is established around reservoir watershed wetland, treating the wetland ecological protection as the core with water purification and flood control, it also can be used for people to carry out scientific research and ecological tourism. Establishing the reservoir watershed wetland park can not only restore the damaged wetland and wetland ecological system with playing its ecological function. It can provides a good opportunity for the protection, rational use of the reservoir watershed wetland to exert its social function. It has important significance to promote the role of the reservoir watershed wetland play.In this paper, firstly defines the concept of reservoir watershed wetlandpark, related theories and the present study on reservoir watershed wetlandpark at home and abroad through reading the relative literature study, then summarize and put forward the current problems and research focus in future. Secondly, study in field and analysis Tang River National Wetland Park and Pan long River National Wetland Park from the two aspects of ecological and landscape effects, the main content from the aspects of planning, design theory, design basis, design principle of reservoir watershed wetland park planning and design are analyzed.Finally, the Yi yuan wetland park plan and design based on the above theoretical research. On the base of Yi yuan Tian zhuang reservoir watershed wetland on the investigation, layout the overall of the Grange wetland park space for the structure of "one center, two axes, six areas" combined with the characteristics of reservoir watershed wetland park and ecological system intrinsic relevance relation and landscape construction of practical needs. Six areas were wetland entrance management service area, wetland purification and display area, idyllic resort, Hawthorn resort, ecological protection forest areas, geographical and cultural resort. Build a series of wetland landscape according to different functions of each functional area requirements and landscape features, enriching the landscape level and demonstrating characteristics of the various functional areas, while playing its role in promoting the social function. Wetland Park in the planning and design combined with the use of technical means, the water quality of the Wetland Park purification as well as the water supply ability was strengthened. The seasonal water level can influence Tian zhuang reservoir reservoir watershed wetland easily and it also affect the wetland landscape of the Wetland Park. Therefore, we eliminate the elevation difference between the wetland and the water level through using the form of field topography and gentle slope to create wetland landscape. In response to the water level change on the impact of the bank, we respectively take the "composite slope protection","stone cage slope protection","plant slope protection" and "natural grass slope protection" form to stable the bank according to different water level and functional requirements, while creating the hydrophilic space. For creating plants landscape, we introduce the ornamental tree species, wetland vegetation and aquatic plants which has high ornamental, anti pollution and water purification with fully consideration of the Wetland Park ecological protection, landscape, water purification and other requirements. We make the plant disposition in different ways according to the different functional area. Above all, the Grange Wetland Park can be desighed to a reservoir watershed wetland park on the wholecombine with ecological function as the restoration of wetland ecosystem and water purification and social function as leisure and tourism.In the Wetland Park Reservoir watershed planning and design, not only need theoretical guidance, but also based on function orientation, resources status of wetland, hydrological conditions, ecological protection and wetland eco-tourism demand in the reservoir watershed wetland, then plan the park. Thus, protect the ecological function of Wetland Park Reservoir Basin and various functions developing the servoir watershed wetland park into a wetland park sets of water purification, flood water storage, ecological protection, recreation and tourism in one.
