基于生态风险评价的城市生态格局修复——以太原市城六区为例

Urban Ecological Pattern Restoration Based on Ecological Risk Assessment——Taking Six Districts of Taiyuan City As an Example

近年来,快速城市化使得城市生态系统面临日益严峻的挑战,城市发展与生态保护之间亟待一个平衡。所以生态格局的构建对于保障城市生态安全、实现城市可持续发展有着深远意义,同时也是景观生态学研究领域的热点之一。文中以太原市城六区生态修复实践为例,通过生态特征与问题识别、生态敏感性分析以及生态干扰度分析,得出生态风险评价结果,阐述融合生态本底、生态过程构建生态格局从而划分生态空间控制线的技术路线与基本方法。

In recent years, the rapid urbanization has made the urban ecosystem face an increasingly severe situation, and a balance between urban development and ecological protection is urgently needed. Therefore, the construction of ecological pattern has far-reaching significance for ensuring urban ecological security and realizing sustainable urban development, and it is also one of the hotspots in the field of landscape ecology research. Taking the ecological restoration practice of the six districts of Taiyuan City as an example, the ecological risk assessment results are obtained through ecological characteristics and problem identification, ecological sensitivity analysis and ecological interference analysis. This paper describes the technical route and basic method of integrating ecological background and ecological process to construct ecological pattern to divide ecological space control line.
