摘　　要：深入探讨景观格局对生态过程的影响机制,将生态风险评价结果作为国土空间布局优化的科学依据,已成为国土空间规划体系的重要内容。本文以我国最大的菱镁产业基地海城-大石桥矿区为研究对象,通过建立综合生态风险指数多元回归模型,形成基于景观格局参数的风险调控规划框架。研究结果表明:(1)采用主成分分析法形成的综合生态风险指数,能够集成多种指标特征,较好反映了综合生态风险状况;(2)以景观格局参数作为变量建立的多元回归模型,对综合生态风险指数具有较好的解释能力,通过敏感性分析能够表征出不同景观格局参数对生态风险的贡献程度;(3)基于生态风险与景观格局的关联机制研究,为空间规划途径的生态风险调控提供了量化依据。本文在景观生态学的格局-过程互馈理论下,提出了一种面向风险过程干预的空间规划设计方法,为矿业城市生态风险的防范与规避提供了一种具有较强可操作性的规划框架。It has become an important part of the territorial planning system to carry out in-depth exploration of the influence mechanism of landscape pattern on the ecological process and to use the results of ecological risk evaluation as the scientific basis for the optimization of the spatial layout.This paper takes Haicheng-Dashiqiao mining area,the largest magnesium industry base in China,as the research object,and forms a risk regulation planning framework based on landscape pattern parameters by establishing a comprehensive ecological risk index multiple regression model.The results of the study show that:(1)the comprehensive ecological risk index formed by principal component analysis can integrate the characteristics of multiple indicators and better reflect the comprehensive ecological risk situation;(2)the multiple regression model established with landscape pattern parameters as variables has a good explanatory capacity for the comprehensive ecological risk index,and through sensitivity analysis,it is able to characterize the extent of the contribution of different landscape pattern parameters to ecological risk;(3)the study based on the correlation mechanism between ecological risk and landscape pattern provides a quantitative basis for the ecological risk regulation by use of spatial planning.This paper proposes a spatial planning and design method for risk process intervention under the pattern-process mutual feedback theory of landscape ecology,which provides a highly operable planning framework for the prevention and avoidance of ecological risks in mining cities.
