摘要
为探讨自然保护地体系中景观格局、破碎化与多样性的协同效应,对浙江三衢国家级森林公园等体系开展研究,借助GIS计算景观格局指标,深入剖析衢州市自然保护地整合优化前后景观格局变化。结果显示:衢州市自然保护地总面积增加9.2%,景观破碎化程度整体降低,核心缀块聚集度与连通性显著提升;但湿地公园与地质公园面积缩减较多,导致类型完整性弱化,局部区域破碎化加剧。
To explore the synergistic effects of landscape patterns,fragmentation,and diversity within the natural protected area system,a study was conducted on systems such as the Sanqu National Forest Park in Zhejiang.Utilizing GIS to calculate landscape pattern metrics,the research thoroughly analyzed changes in landscape patterns before and after the integration and optimization of protected areas in Quzhou City.The results indicate that the total area of protected areas in Quzhou increased by 9.2%,with an overall reduction in landscape fragmentation and significant improvements in core patch aggregation and connectivity.However,wetland parks and geological parks experienced considerable area reductions,leading to weakened typological integrity and intensified fragmentation in localized regions.
