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.%港口开发建设对城市的影响区域主要集中在港口附近，港口开发带动了临港产业的发展，港口建设开发过程中对土地资源(尤其是生态用地)的占用导致建设用地需求与生态用地保护之间的矛盾日益加剧，港口土地资源供应越来越紧张。选取厦门港港区及港区后方10 km范围内的陆域为研究区，从土地自然生态属性方面考虑，采用建设用地适宜性评价方法，在不改变区域内已开发建设用地用途的情况下，对港口区域剩余土地资源进行适宜性评价，得到适宜、勉强适宜、不适宜建设用地面积及分布。结果表明：厦门港研究区域内剩余土地资源的适宜、勉强适宜、不适宜建设用地面积分别为185．43、61．56、174．75 km2。说明厦门港口区域建设开发强度较大，尤其是厦门市区内土地资源承载力较弱，已不适宜进行大规模开发建设。
