辽河三角洲滨海湿地景观规划预案设计及其实施措施的确定

The landscap planning scenarios designing and the measures identification in the Liaohe River Delta wetland

系统介绍了景观规划“预案”研究的有关概念及预案设计的原则和方法。以辽河三角洲滨海湿地为实例 ,对其协调区域开发与湿地保护的景观规划进行了多预案设计 ,运用景观生态决策与评价支持系统 ( LEDESS)确定实现各预案所需措施并对其涉及的空间范围进行了模拟和定位。模拟结果以空间直观的形式显示实现各预案景观规划目标所需采取的措施和涉及的空间范围 ,可为区域开发的方法和模式选择、湿地保护的生态工程设计提供具体的参考依据。

The concept,principle and methodology of scenarios study and its application in regional landscape planning were introduced.As a case study in Liaohe River Delta wetland aiming to compromise the intensively competed landuse between the rgeional development and nature conservation,three landuse scenarios were designed and elaborated according to the different landscape targets.Based on Landscape Ecological Decision and Evaluation Support System(LEDESS),the measures to realize landscape targets were developed and their relevant spatial scope were identified.The spatially explicit results produced from LEDESS can provide the foundation and be served as practical references for the wetland ecological engineering to achieve the landscape targets of the scenarios.
