Later, this paper used a questionnaire survey to investigate the impact of the urban coastline landscape system on the environment. Questionnaire survey results show that the environmental pollution account can value ecological bearing capacity of ecological pressure index, biomass production account can value ecological bearing capacity of natural ecological carrying capacity of the largest, social and economic value of ecological carrying capacity can update resources per capita value, environmental pollution account can value ecological bearing capacity of ecological security machine is not safe.
