中文摘要：

文章采用东中国海二维潮波模型，基于2006年夏季大潮潮流数值的计算结果对江苏沿海潮差能和潮流能开展了区域分布研究。就潮差能而言，通过对比分析《江苏沿海功能区划》所拟定的3个潮汐电站站址（灌河口、射阳河口和长江口北支）所处的地理位置及相应的潮汐要素，发现灌河口站址自然条件相埘较优，椎荐采用单坝单向水库在该区域进行潮差能的开发。就潮流能而言，通过分析区域内潮流平均流速和椭网图的分布特征，发现江苏沿海南部的小洋口地区和长江口南支的北港、南槽地区具有较好的潮流能开发利用潜力。

英文摘要：

Based on the result of spring tidal flow numerical value in summer of 2006, this paper has taken east China two-dimensional quantitative model to estimate the distribution of tidal wave energy and tidal stream energy in Jiangsu province coast. For tidal wave energy, by comparing and analyzing the geographical position and tidal climate with the following three sites： Guauhe estuaE~, Sheyang estuary and the North branch of Yangtze estuary which plan to build tide energy farm in 〈 Marine Functional Zoning In Jiangsu Province 〉, it showed that the natural conditions in Guanhe estuary was better than the others. Based on this result, this paper proposed to use the type of barrage which has single basin and obtain energy just from ebb tide in Guanhe estuary. For tidal stream energy, the distribution of averaged tidal stream velocity and flow vectorgraph showed that Yangkou area in the southern of radial sandy ridge, the north port and south channel of Yangtze estuary have abundant tidal stream energy.
