Using Ecological Footprint Model for Port Ecosystem Sustainability Assessment

Construction of coastal ports makes port area and nearby sea area become high risk region of ecological emergency and environmental pollution. It is helpful for providing references to protect ecological environment of port by quantifying port ecological carrying capacity. This paper will transfer resources and energy consumed in port production and operation to four ecological productive lands, including arable land, woodland, lawn and water area. Based on them, build port ecological footprint model, considering biological resource, energy and construction land ecological footprint. Furthermore, research resource demand of port ecological system. By comparing the demand and supply of ecological resource, evaluate ecological carrying capacity of port.
