国土空间视角下生态安全格局构建方法综述

在国土空间规划改革的背景下,探讨生态安全格局的构建,研究其构建依据和方法,对优化国土空间开发新格局和推进生态文明建设具有重要的理论和实践意义。文中阐述生态安全格局的概念,梳理了生态安全格局构建依据与评价方法。其中,生态安全格局构建依据主要包括生态保护重要性评价、生态系统服务功能评价、生态敏感性评价等,评价方法主要指生态安全评价法。在此基础上,分析生态安全格局构建的步骤、方法和特点,并从以下3个方面提出建议:1)改进、优化生态源地识别方法;2)生态安全格局的研究应与当前生态政策相结合;3) 注重生态安全格局有效性评价。研究旨在为国土空间规划背景下生态安全研究、生态保护政策制定提供参考和借鉴。

Review on the Constructing Methods for Ecological Security Pattern From the Perspective of Territorial Space

Under the background of territorial spatial planning reform, it is of great theoretical and practical significance to explore the construction of ecological security pattern, study the basis and method of its construction, optimize the pattern of territorial spatial development, and promote the construction of ecological civilization. The paper expounds the concept of ecological security pattern and the development process of its research, combs the basis and evaluation methods for the construction of ecological security pattern. The basis mainly includes the evaluations of ecosystem service function, ecological sensitivity, and ecological protection importance, etc., while the evaluation methods mainly refer to the ecological security evaluation method. Further, the procedures, methods and existing problems of the current ecological security pattern construction are sorted out and analyzed. On this basis, the following suggestions are proposed: 1) Improving and optimizing the methods for ecological source identification. 2) Combining the ecological security pattern research with current ecological policy; 3) Focusing on the effectiveness evaluation of ecological security pattern. The article is aimed at providing reference for ecological security research and ecological protection policy formulation under territorial spatial planning.
