生态安全约束下的城乡生态格局优化方法——以海南省文昌市木兰湾地区概念规划为例

Improving Urban Rural Ecological Safety Pattern With Constraints: Conceptual Planning Of Mulan Bay Area, Wenchang, Hainan Province

研究表明,城乡生态安全问题与区域生态格局密切相关。文章以生态学相关理论为支撑,提出了生态安全的三大约束表征,即生态服务约束、生态风险约束和生态健康约束,在此基础上提出生态安全约束下的城乡生态格局优化方法,即基于生态服务约束确定城乡开发的规模和总量;基于生态风险约束锁定需要保护的生态空间;基于生态健康约束构建以生态流为基础的结构性生态联通网络。文章详细介绍了该方法在海南省文昌市木兰湾地区概念规划中的应用,以期为类似的城乡规划实践提供一种新的思路。

Urban ecological pattern and regional ecological pattern are highly correlated.The paper raises three characters of ecological safety:service constraint,risk constraint,and health constraint based on ecological theory.The paper proposes defining urban rural development capacity based on ecological service constraint,protected ecological space based on ecological risk constraint,and structural network based on ecological health constraint.The method is practiced in the conceptual planning of Mulan Bay area,Wenchang city.
