Ecological carrying capacity (ECC) evaluation provides important references for sustainable development of regional economy and society. However, the methods of conventional regional ECC evaluation do not include assessment on resource depletion or environmental effects of specific planning. Using the pressure (P)-state (S)-response (R) model, taking a coastal port master planning as an example, the technical solutions for strategic environmental assessment (SEA) of ECC on coastal port master plan was proposed. Based on the analysis results on natural resources, environmental carrying capacity and ecological risks of coastal port master plan of the coastal tidal, intertidal and sublittoral zones, the technical framework for SEA on coastal construction projects were established with detailed illustrations. The framework included carrying capacities of land resources in tidal zone, shoreline resources, and reclaiming land derived from sea in intertidal zone, as well as the water environmental carrying capacity of the offshore marine areas. The results can be used as scientific base for the sustainable use of coastal natural resources, and references for building new SEA system of ECC of project plans.
