The development of green infrastructure was impeded by its attributes on multi-scale and ambiguous definition,it is stated that the relevant research on green infrastructure ought to be devided into two parts as the facility-scale and the system-scale,to alleviate the flaw.Based on the systematic perspective,it is expounded that the role aquatic ecosystem resilience promotion plays in guaranteeing the sustainable provision of the ecosystem services that is produced by green infrastructure system,the approach to promoting the aquatic ecosystem resilience is identified as the landscape pattern optimization.The Linjiacun Town is taken as the study area where the resilience promotion research is conducted,based on the "patch-corridor-substrate" theory,the ecological substrate,ecological sources,ecological corridors and ecological nodes are clarified,which propels the ensuing exploration on the landscape pattern optimization,and the ecological water network is structured to strengthen the connectivity of the aquatic ecosystem.The evaluation values of the ecological resilience improvement before and after landscape pattern optimization are attained,and the values are 3.38 and 4.03 respectively,which indicates that the effect increased by 19.23%.Thus it is illustrated that the concrete avenue of promoting the aquatic ecosystem resilience,which makes up the deficiency in probing the acceleration of aquatic ecosystem resilience caused by the landscape pattern optimization quantitatively.
