【摘要】 遥感技术用于广袤宽阔、复杂多变而难以实地勘测的潮间带资源调查是科学和最有效的选择。作者以三期低潮位卫星遥感数据图像为基础，对江苏沿海潮间带滩涂资源的总量、分布特点、发展趋势及开发利用前景进行了分析，指出了江苏滩涂资源总量呈减少趋势，匡围量大于可供匡围的滩涂资源生长量，应加强对滩涂资源开发利用规划和统一管理。更多还原

【Abstract】 It is quite efficient to apply the remote-sensing technology to investigating the tidal flat resource, which is enormous and complex. Based on the remote-sensing digital images of three different times taken by satellites, the authors analyze the characteristics of the tidal flat resource in Jiangsu Province, including its total quantity, distribution, developing trend and applying prospects for application. The results show that in Jiangsu Province, the tidal flat resource tends to decrease, because the area of the beach which has been utilized is larger than that which has been reproduced. Therefore, better management should be emphasized when utilizing the tidal flat resource.更多还原
