【摘要】：湿地生态过程与发展状态是动态变化的,湿地景观设计取决于现状湿地所处的状态,更被预定目标下的湿地生态恢复状况所左右。本方案对湿地的保护与恢复就是基于动态时空下,以可预见其所将受到的干扰的前提下进行的景观设计,尽管干扰程度、发生时间、湿地状态是条件预测下得出的,但是这些可变量的因子带来的干扰却是可以确定的,所以这样的景观设计形式来进行湿地生态保护与恢复是可行的。在拆除防洪堤坝的前提下以开放式的防洪和蓄净管理途径来替换建设防洪工程这种解决洪涝问题的方法,通过不同级别洪泛侵袭的水文过程模拟,预景湿地范围及类型分布。这种解决途径在景观设计中以水系网络、湖泊、池塘、泄洪区、低洼地、阶梯式亲水廊道的整体设计来体现。既能通过疏浚水系发挥河流湖泊湿地等调蓄功能,又能构筑成更多以自然调节的方式来抵御洪水的防洪网,既能满足人们对人身财产安全的保障又真正做到了替换和减轻人类干扰对生态环境的破坏。论文将洲滩湿地与其所处的河流流域所组成的湿地生态系统视为一处湿地景观,运用景观设计来解决湿地的生态退化问题。把洲滩湿地视为一个景观生态系统,探讨洲滩湿地的生态恢复。提出以构筑蓄水池这一绿色生态基础设施来替代原来筑堤防洪工程,替换人类干扰方式,少人为施工,达到最小干预,促进洲滩湿地生态自然恢复,对于推进洲滩湿地生态恢复理论与实践的不断发展与完善,有极其重要的意义。也为解决湿地生态恢复问题献上一份绵薄之力。
[Abstract]:Wetland ecological process and development state are dynamic changes, wetland landscape design depends on the status of the wetland. The protection and restoration of wetland in this scheme is based on the landscape design under dynamic time and space, in order to predict the disturbance it will be subjected to, although the degree of disturbance, The time of occurrence, the condition of the wetland is predicted under the condition, but the disturbance caused by these variable factors can be determined. Therefore, it is feasible to carry out wetland ecological protection and restoration in such a landscape design form. On the premise of removing flood control dikes and dams, an open flood control and clean storage management approach is used to replace the construction and flood control project, a method to solve the flood and waterlogging problem. Through the hydrological process simulation of flood invasion of different levels, the scope and type distribution of pre-view wetland are simulated. In landscape design, this solution is based on water network, lakes, ponds, flood discharge areas, low-lying areas, etc. The overall design of step hydrophilic corridors can not only exert the regulation and storage function of rivers, lakes and wetlands through dredging water systems, but also construct more flood control networks that can resist floods in natural ways. It can not only satisfy the security of people's life and property, but also replace and reduce the damage to ecological environment caused by human disturbance. The wetland ecosystem composed of the marshland and its river basin is regarded as a wetland landscape in this paper. The ecological degradation of wetland is solved by landscape design. The wetland is regarded as a landscape ecosystem, and the ecological restoration of marshland is discussed. The green ecological infrastructure of reservoir is proposed to replace the original flood control project of embankment. The replacement of human disturbance mode, the less artificial construction, the minimum intervention, the promotion of natural restoration of wetland ecology in the beach, and the continuous development and improvement of ecological restoration theory and practice of beach wetland, It is of great significance to solve the problem of wetland ecological restoration.
