| 以营口市南部海岸为例，采用高空间分辨率卫星遥感影像建立了沿海盐田各组成部分的影像特征和面向对象的盐田空间格局卫星遥感影像信息提取技术流程，分析了沿海盐田空间格局特征及其变化.结果表明：面向对象的高空间分辨率卫星遥感影像信息技术可以详细地将沿海盐田空间格局划分为纳潮池、蒸发池、初级制卤池、中级制卤池、高级制卤池、结晶池和储盐池，以及养殖池、建设地、草地、坑塘湿地等非盐田类型.我国北方区域盐田空间格局组成的纳潮池、蒸发池、制卤池、结晶池、储盐池的面积基本比例为15∶45∶26∶4∶1.大规模的人类开发导致营口市南部海岸盐田空间格局变化显著，纳潮池和蒸发池等盐田组成池塘类型面积收缩强度分别为13.67、8.08，而草地、建设地等非盐田类型面积收缩强度分别为-10.27、-25.41. |

| Abstract: |
| This paper studies the spatial pattern of sail ponds in south coast of Yingkou as example. The high resolution remote sensing images were employed to obtain coastal salt pond engineer information. And the classification technique flow of remote sensing image for spatial pattern of coastal salt pond engineer based on objectoriented method is established. Then spatial pattern characteristics of salt ponds engineer and its change was analyzed. The result show that the objectoriented method for high resolution satellite remote sensing images can classify spatial pattern of coastal salt ponds engineer to tidal pond， evaporation pond， primary brine pond， intermediate brine pond， senior brine pond， crystallizing pond， salt storage pond， and other types such as fishing pond， building land， grassland and wetland. As results， the area ratio of tidal pond， evaporate pond， brine pond， crystallizing pond， salt storage pond in the north China coast is 15∶45∶26∶4∶1. The spatial pattern of salt pond engineer has changed obviously by intensity human activities. Contraction intensity of tidal pond and evaporation pond are 13.67 and 8.08， while for grassland and building land are -10.27 and -25.41． |
