中文摘要：

从自然适宜性、生态适宜性和经济可行性角度构建了沿海滩涂耕地后备资源开发适宜性综合评价体系，综合运用了专家打分法、极限条件法和综合指数法等方法及AreGIS的空间分析功能，采用逐级修正法确定适宜性开发等级。以江苏省盐城市为例，将自然、生态适宜性评价结果进行叠加计算，得到沿海滩涂耕地后备资源适宜开发的面积和空间分布状况，并从经济适宜性方面探讨了沿海滩涂耕地后备资源开发的经济可行性。研究结果表明，盐城市自然高度适宜性开发的滩涂面积为67395．01hm^2，中度适宜开发的面积为50896．04hm^2；考虑生态适宜性评价结果后，高度适宜开发的滩涂面积为30327．75hm^2，中度适宜开发的面积为40137．92hm^2，二者占未利用滩涂的51．06％；盐城市沿海滩涂耕地后备资源开发在经济上全部适宜，且开发经济价值很大。本研究可为沿海地区制定沿海滩涂耕地后备资源开发规划提供科学的参考依据。

英文摘要：

Evaluating the suitability of reserved coastal mudflat for land development provides a scientific basis for its exploitation and utilization. The evaluation systems of the reserved coastal mudflat were established form three aspects： physical suitability, ecological suitability and economic suitability. The evaluation system integrated Delphi method, critical conditions method, and comprehensive index method through stepwise correction to determine the suitability of development level. The study area was in Yancheng City, Jiangsu Province. Using the spatial analysis function in ArcGIS, area and spatial distribution of reserved coastal mudflat for land development suitability under different conditions were determined and the economic viability of reserved coastal mudflat for land development was explored. The results indicated that the areas of high and moderate suitability based on natural conditions were 67395.01 and 50896.04 hm^2 respectively. Further considering the ecological suitability, the areas of high and moderate suitability were 30327.75 and 40137.91 hm^2 respectively （51.06% of the reserved coastal mudflat）. Lastly, when the economic feasibility factors were taken into account, all the reserved coastal mudflat could be developed. This study can be a reference for policy making regarding the development and planning of reserved coastal mudflat.
