摘　　要：随着新型城镇化的推进,建设用地扩张迅速,苏南水网地区面临生境破碎与生态退化等问题,构建绿色基础设施网络是整合破碎生境斑块、提升生态系统稳定性和整体性的有效措施。本研究以苏州吴江区东北部南星湖片区为例,基于“网络中心-连接廊道-战略点”的构建模式,运用MSPA、InVEST模型与景观连通性提取网络中心,结合电路理论提取连接廊道、战略点,构建水网地区绿色基础设施网络,共识别网络中心18处,以湖泊、林地生态用地为主,呈现东部密集西部稀疏的分布特征;提取连接廊道35条,空间分布呈现北部较为密集、南部相对稀疏的特征;选取夹点和障碍点2种战略点共16处,包括湿地、耕地等用地类型,在同里湖、石头潭附近分布较多。研究综合考虑景观要素的生态服务重要性和生态功能连通性构建水网地区绿色基础设施网络,对于改善区域生态环境质量与促进生态系统稳定与可持续发展具有积极意义。With the development of new urbanization and the rapid expansion of construction land,the water network area in southern Jiangsu is facing problems of habitat fragmentation and ecological degradation.The construction of green infrastructure network is an effective measure to promote ecological space connectivity and protect biodiversity.Taking Nanxing Lake area in the northeast of Wujiang District of Suzhou as an example,based on the model of“identification of network center-extraction of connection corridor-selection of strategic points”,MSPA,InVEST models and landscape connectivity were used to identify the network center,combined with circuit theory to extract connection corridor and select strategic points,a green infrastructure network was constructed in the water network area.There were 18 consensus network centers in the study area,mainly lake and forest ecological land,with dense distribution in the east and sparse distribution in the west.Thirty-five connecting corridors were extracted,and the spatial distribution was dense in the north and sparse in the south.Sixteen strategic points,including wetland,cultivated land and so on were selected,which were mostly distributed near Tongli Lake and Shitan Lake.Considering the importance of ecological services of landscape elements and the connectivity of ecological functions,the study on the construction of green infrastructure network in water network area has positive significance for improving the quality of regional ecological environment and promoting the stability and sustainable development of ecosystem.
