Study on Evaluation of Land Carrying Capacity of Xiamen Port Planning

Urban areas of influence of port development and construction are mainly concentrated near the ports, which result in the development of port-neighboring industry. In the process of constructing and developing of ports, the occupation of land resources especially the ecological land causes the contradiction between the construction land demand and ecological land, and leads to short supply of land resources. Taking the Xiamen port area and the terrestrial scope of 10 kilometers behind it as the study region, the method of ecological suitability evaluation of construction land was adopted to obtain the area and distribution of suitable, barely appropriate and inappropriate lands, considering the land ecological attributes and regardless of function changes of the lands that had been developed. Results show that the rest area of suitable, barely appropriate and inappropriate lands is respectively 185.43, 61.56, 174.75 square kilometers. The construction and development intensity of study region is great, and especially the land carrying capacity of Xiamen urban area is weak; so it is not suitable for more large-scale development and construction.
