摘　　要：随着城镇化建设发展,城市绿色基础设施网络破碎化程度日益加剧,加强绿色基础设施网络连通性,优先保护连接廊道中对区域生物多样性保护和区域生态系统服务功能具有重要意义的"夹点"区域尤为重要.以郑汴都市区为例,采用形态学空间格局分析(MSPA)提取绿色基础设施网络要素中的"中心"和"连接",然后采用最小路径方法创建潜在的绿色基础设施连接廊道,构建连通的绿色基础设施网络,最后基于电路理论识别潜在连接廊道的"夹点"区域,制定优先保护策略.研究结果表明,郑汴都市区47.26%的用地可作为绿色基础设施用地,但景观连接度较低,破碎化非常严重,研究区65.98%的连接廊道由农田构成,区域连接廊道的组成类型单一,以耕地为主,提供区域生态系统服务能力较低.MSPA方法侧重结构性连接,而电路理论则通过功能性连接进行补充分析,两者结合能够更加科学全面地识别绿色基础设施网络要素,从而使得绿色基础设施网络的构建和保护策略的制定更加科学有序.With the development of urbanization, the fragmentation of the city＇s green infrastructure network has become increasingly worsen. The connectivity of the green infrastructure network should be strengthened. It is particularly important to pay attention to give priority to the protection of the ＂pinch point＂ in connection corridors that is important for regional biodiversity conservation and regional ecosystem service functions. Taking the Zhengzhou-Kaifeng metropolitan area as an example, the morphological spatial pattern analysis （MSPA） was used to extract the ＂center＂ and ＂connection＂ of the green infrastructure network, and then the minimum path method was used to create a potential green infrastructure connection corridor. Finally, the ＂pinch＂ area of the potential connection corridor was identified based on circuit theory and a priority protection strategy was developed. The results show that 47.26 % of the land in the Zhengzhou-Kaifeng metropolitan area can be used as green infrastructure land, but the landscape connection degree is low and the fragmentation is very serious. 65.98% of the connection corridor in the study area are composed of farmland. The composition type of the regional connection corridor is single and the ability to provide regional ecosystem services is poor. The MSPA method focuses on structural connections, while the circuit theory complements the analysis through functional connections. The combination of the two makes the comprehensively, thus strategies will he more identification of the green infrastructure network elements more scientifically and the construction of the green infrastructure network and the formulation of protection scientific.
