摘要
城市生物多样性保护网络的构建有助于保障城市内的生物多样性,提高城市生态系统稳定性。为探索城市生物多样性保护路径,以广州市为例,基于自然资源识别的方法开展了生物多样性源地识别、生态连接度分析、潜在生态廊道模拟等研究。结果表明:研究区生物多样性源地面积为2634 km^(2),占土地总面积的35.4%;高生态连接度区域面积占比61.02%,低生态连接度区域面积占比29.93%,中生态连接度区域面积占比9.05%;生态网络分析出潜在生态廊道36条,应重点加强该区域生态网络修复;基于“斑块-廊道-基质”模式,构建广州“九片六核、三纵五横”的生物多样性保护网络。研究结果可为广州市编制国土空间生物多样性保护规划提供参考,也可为其他地区开展系统性生物多样性保护工作提供借鉴。
The construction of the city's biodiversity protection network helps to safeguard the biodiversity within the city and improve the stability of the urban ecosystem.In order to explore the path of urban biodiversity protection,Guangzhou was taken as an example,and research was conducted on biodiversity source identification,ecological connectivity analysis,and potential ecological network identification based on natural resource identification methods.The results showed that the biodiversity source area in the study area was 2634 square kilometers,accounting for 35.4%of the total land area.The area with high ecological connectivity accounted for 61.02%of the total area,while the area with low ecological connectivity accounted for 29.93%,and the area with medium connectivity accounted for 9.05%.A total of 36 ecological corridors were identified through potential network analysis,which should be given priority for restoration.Based on the“Patch-Corridor-Matrix”theory,a biodiversity protection network pattern of“Nine patches,six cores,three verticals and five horizontals”was constructed for Guangzhou.The research results can provide reference for the compilation of national land spatial biodiversity protection planning in Guangzhou,as well as for other areas to carry out systematic biodiversity protection work.
