摘要: 生态安全和生态安全格局是区域生态保护研究的热点议题,输电线路工程的环境影响评估通常对生态安全考虑不足。本文以闽粤联网工程(福建段)区域为例,采用形态学空间格局分析法、最小累积阻力模型和重力模型获得区域“源地-廊道-节点”生态安全格局,得到由输变电工程建设产生的生态安全影响。研究结果表明,2020与2021年研究区生态源地面积分别占区域面积的47.29%、40.16%,生态源地集中分布于研究区的中西部。重要生态廊道有21条,整体呈现“三角形”的空间分布;研究区有4个生态安全保护区,即大帽山、峰头水库、高峰谷、白鹭森林公园生态安全保护区域。其中,大帽山与白鹭森林公园保护区中 “源地-廊道-节点”占比较大;2020和2021年闽粤联网线路2 km生态影响区内涉及生态节点3个,生态廊道总长分别为52.09、58.46 km,生态源地总面积分别为185.63、154.42 km2。研究结果明确了闽粤联网工程(福建段)的生态安全重点保护区,为制定生态保护措施提供科学依据。

Abstract: Ecological security and ecological security pattern are hot topics in regional ecological protection research, and the environmental impact assessment of power transmission line project,which is relatively insufficient to consider ecological security. This paper takes the area of Fujian-Guangdong linkage project (Fujian section) as an example, and adopts morphological spatial pattern analysis (MSPA), minimum cumulative resistance (MCR) model and gravity model to obtain the regional “source-corridor-node” ecological safety pattern. The ecological security pattern of “source-corridor-node” is obtained by using morphological spatial pattern analysis (MSPA), minimum cumulative resistance (MCR) model and gravity model, and finally the ecological security impact of power transmission project construction is obtained. The results show that, in 2020 and 2021, the ecological source areas in the study area accounted for 47.29% and 40.16% of the regional area, respectively, and the ecological source areas are concentrated in the central and western parts of the study area. There are 21 important ecological corridors with an overall spatial distribution of triangle; four ecological safety protection areas are distributed in the study area, for Damao mountain, Fengtou reservoir, Gaofeng valley and Egret forest park, among which Damao mountain and Egret forest park have a large proportion of ecological “source-corridor-node”. In 2020 and 2021, 3 ecological nodes, 52.09 and 58.46 km of ecological corridors,185.63 and 154.42 km2 of ecological source areas are involved in the 2 km ecological impact zone of Fujian-Guangdong linkage line, respectively. The results of the study clarify the key ecological security protection zone of Fujian-Guangdong linkage project (Fujian section) and provide a scientific basis for formulating ecological protection measures.
