摘要
针对城市建设导致生境破碎带来的生态威胁和日趋严格的生态保护要求,在“双碳”背景下,综合碳储量和景观形态学空间格局分析识别生态源地,采用MCR模型识别生态廊道,构建龙华区生态安全格局。识别了龙华区生态源地共7块,主要为光明森林公园、观澜森林公园、阳台山等重要生态功能区;提取了生态廊道9条,总长53 km,纵横呈“目”字形分布;构建了龙华区“一环双廊道多节点”的生态安全格局,形成重点保护、全域串联的生态保护格局,以促进生态重要区域保护和生物交流。
In response to ecological threats from habitat fragmentation due to urban development and stringent ecological protection requirements under the“dual carbon”context,this study conducted an analysis integrating carbon storage and landscape morphology spatial patterns to identify ecological source areas.Using the MCR model,it constructed ecological corridors and developed an ecological security framework for Longhua District.Seven ecological source areas were identified,including key zones such as Guangming Forest Park,Guanlan Forest Park,and Yangtai Mountain.Nine ecological corridors,totaling 53 kilometers in length,were delineated and arranged in a grid-like pattern resembling the character“目”.This led to the establishment of an ecological security pattern characterized by“one ring,dual corridors,and multiple nodes”,forming a key protection and comprehensive linkage ecological framework to promote the conservation of significant ecological areas and facilitate biological exchanges.
