风景名胜区规划实施的景观生态效应——以南京市幕燕风景名胜区为例

景观生态学不仅可为风景名胜区的规划设计提供新的理论和方法 ,而且通过对规划实施后可能引起的景观生态效应的研究 ,还可以为进一步完善改进规划提供重要的科学依据。本文以南京市幕燕风景名胜区为例 ,从风景区的景观格局、景观生态质量、景观稳定性等方面分析了风景区规划实施的景观生态效应 ,并据此提出改进完善风景区规划的建议。

Research on landscape ecological effects of scenic spot planning:a case study of Muyan Scenic Spot, Nanjing

Landscape ecology could provide not only new theory and methods for scenic spot planning, but also scientific bases for improving the planning through study on the possible landscape ecological effects caused by implementing the planning. Taking Muyan Scenic Spot of Nanjing as an example, the possible changes before and after implementing the planning in such aspects as landscape pattern, landscape ecological quality, landscape stability are analysed. Based on this study, improvement of the scenic spot planning has been proposed. This paper contains the following contents: 1)According to the requirement of landscape evaluation and planning, landscape unit survey and mapping are carried out in Muyan Scenic Spot, and a landscape classification system in this area is established; 2)based on the scenic area planning, possible landscape changes are analyzed on the assumption that the planning has been implemented; 3)changes in landscape spatial structure after implementing the planning are analyzed by using landscape spatial pattern analysis method; 4)landscape ecological quality before and after implementing the planning is qualitatively and quantitatively estimated; 5)based on the analyses of recovery, persistence, and noise immunity of the landscape, landscape stability before and after implementing the planning is evaluated; and 6)according to the above evaluation and analysis, landscape ecological effects of the scenic spot are concluded and suggestions on planning improvement are made.
