沿海地区既是人类活动剧烈区又是生态环境敏感脆弱区，其耕地利用变化与生态环境效应研究亟待加强。以江苏沿海为研究区域，基于耕地集约利用和生态服务价值模型，估算沿海19个县市耕地集约利用水平与生态服务价值，分析其时空演变特征，探讨沿海地区耕地集约利用与生态服务价值的动态变化特征。结果显示：（1）2000—2010年江苏沿海19个县市耕地集约利用水平显著提高，2000年、2005年、2010年其平均值分别为0.181，0.251和0.372，空间格局变化特征显著，Ⅰ级区范围呈缩小趋势，Ⅱ级区和Ⅲ级区范围有所增加。（2）耕地生态服务价值呈波动变化，2000年、2005年、2010年其耕地生态服务价值平均值分别为1.68×109元，1.58×109元，1.55×109元，苏北地区耕地服务价值呈下降趋势，苏南地区呈上升趋势，耕地生态服务价值Ⅰ级区呈零散分布，Ⅱ级区范围在扩大，Ⅲ级区范围呈减少态趋势。（3）江苏沿海地区耕地集约利用水平与生态服务价值呈显著负相关，不同典型年份其相关系数分别为-0.700、-0.662和-0.682，不同经济梯度下其相关系数存在明显差异，经济发达的苏南地区相关系数值大于苏北地区，苏南地区相关系数呈下降趋，而苏北地区呈上升趋于。

Coastal area is not only the intense human activity area but also ecologically sensitive areas, the land use change and ecological environment research should be strengthened. In this study, the study of Jiangsu coastal area, based on intensive use of land and ecosystem service value assessment model, the election of 2000, 2005, 2010, for the time section, estimated 19 coastal counties and cities the level of intensive use of land and the value of ecosystem services, analyzed its temporal and spatial variations, of coastal land use and ecosystem service value of intensive dialectical relationship. The results showed that: of the 19 coastal counties and cities in Jiangsu during the period of intensive use of arable land was significantly improved, and its average value, respectively, 0.181, 0.251 and 0.372, spatial structure change significantly. The farmland ecosystem service value fluctuated, the average land value of ecosystem services were 1.68×109 yuan, 1.58×109 yuan, 1.55×109 yuan, the value of northern land services downward trend, the rise in south trends in land value of ecosystem services were scattered areas of grade Ⅰ, Ⅱ grade zone to expand, Ⅲ grade state trend of decreasing area. The coastal areas of intensive land use and ecological service value was significantly negatively related to the study period the correlation coefficients were -0.700, -0.662 and -0.682, the correlation coefficient gradient law significantly related to the economically developed areas in southern Jiangsu coefficient was greater than in northern regions, the correlation coefficient decreased in southern trend, the rise tends to northern.
