| Reservoir wetland is the outcome of people to change or remodel the natural riverie wetlands territorially. It not only has some functions as reservoir but also has the ecological function. And its ecological property is between land and water ecological system and in the overlapping space area between the two kinds of the extended system, which is an important part of the wetland types. However, with the overuse of the wetland resources and environmental pollution, the wetland resources degenerate greatly. So how to ease and manage wetland degradation and attenuation has become the focus on wetland research of the experts at home and abroad. For China, only protecting the existing wetland resource is not enough, recovering the degraded or what is being degraded wetland is the top priority. In the field of wetland landscape design, how to combine wetland landscape design, wetland landscape restoration, wetland resources tourism development and the economic value of wetland resources organically is becoming an issue that need to be resolved.Based on the landscape ecology, landscape design science and sustainable development theory, wetland ecological system design and reconstruction of restorative theory and leisure theory and aesthetic theory, the research proposes the related design methods. And the research also takes the Pipa Temple Reservoir in Henan as a case to study. And the main research achievements are as follows:(1) Based on the above theories, the study summarizes the contents, purposes and principles of the design to restore the reservoir wetland landscape. After this, the researcher proposes five design methods and also analysis each of them.(2) The five methods are as follows. First, it is the restorative design on the ecological aspect, such as the functional layout of the overall arrangement, the landscape structure, the breakdown design of the water system improvement, soil design recovery and vegetation recovery; Second, it is the restorative design about the wetlands landscape, such as the overall arrangement of the landscape structure, view control and traffic organization, the breakdown design of hydrology landscape and arrangement of plants. Third, it is the restorative design of wetland tourism recreation, such as the overall arrangement of the traffic organization, tourist point, the design of tourist route and the breakdown design of protecting creatures, which aims to reduce the influence on them. Fourth, it is the restorative design of the wetland aesthetic, such as the overall arrangement of the view control, the design of tourist point, the breakdown design of hydrological transformation and the exploration of vegetation landscape and landscape lines. Fifth, it is the restorative design of wetland economic, such as the overall arrangement of the tourist point, the arrangement of the tourist route, the breakdown design of floristic option, silt processing, and water improvement and so on.(3) The study will take the Pipa Temple Reservoir for example and apply the methods of restoration concretely. In the overall arrangement of restorative design, the function zone introduces three partitions. And they are the primary area, sub region and the panel point. Then the landscape structure will be arranged by four levels. And they are the border of landscape ecology, gallery, matrix and plaque. Within these, the research gives a full respect to the original ecological system and restores all kinds of the wetland landscape organically. And in the special design of the wetland landscape restoration, the author will introduce the ablation zone of the wetland, vegetation, the form of water system, soil and creatures and give them a sound recovery.The complexity and diversity unique to the Reservoir wetlands determines the difficulty of the Pipa Temple Reservoir wetland landscape restoration design. The construction and development of the Reservoir wetland landscape restoration in our country is still in its infancy, where there are many places to practice and time to prove. |
