Abstract: As a new way to solve urban problems, Green Infrastructure (GI) can provide multifunctional ecosystem services to cities and their inhabitants.Taking the Hanjiang Ecological Economic Zone as the study area, the paper adopts the methods of morphological spatial pattern analysis(MSPA), landscape index method and minimum cumulative resistance model (MCR) to construct the GI network from 2010 to 2020 to reveal its temporal and spatial evolution.The following conclusions can be made.(1) In the past ten years, the total area of GI landscapes in the research zone accounted for about 58% of the total area of the research zone with annual average growth rate of 2.6‰ and it will continue to increase.Among them, the core area occupied about 86.08% of the total area of GI landscape.(2) The GI landscape around the city was severely affected by urban expansion.Its area was continually shrinking and the structure tended to be simplified.Thereby, we meet great challenges to protect and restore it.(3) The comprehensive resistance value decreased from northwest to southeast, while the high-resistance area showed a continuous trend of expansion.The potential corridor constructed on resistance was densely distributed in the middle and upper reaches of Hanjiang, whose number has increased from 8.70% of negative growth to 63.64% of positive growth.Moreover, the number of ecological nodes have continuously increased to 1,916, which reflected the fragmentation phenomenon in the upper reach was not effectively stopped.(4) The network structure presented a pattern of “local connectivity and overall looseness”, which greatly limited the scope of species dispersion and energy flow.The number and area of GI sources were the key to network structure optimization.
