【摘要】：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]:Taking the southern coast of Yingkou City as an example, the image features of each component of coastal salt field and the technology flow of object oriented satellite remote sensing image extraction of salt field spatial pattern are established by using high spatial resolution satellite remote sensing image. The characteristics and changes of spatial pattern of coastal salt fields are analyzed. The results show that the spatial pattern of coastal salt fields can be divided into tidal basin, evaporation pool, primary brine basin, intermediate brine pool, advanced brine pool, crystallization pool and salt storage pool by object-oriented high spatial resolution satellite remote sensing image information technology. As well as breeding ponds, construction land, grassland, pothole wetland and other non-salt-field types. The basic proportion of the area of the tidal basin, evaporation pool, brine making pool, crystallization pool and salt storage pool is 15: 45: 26: 4: 1, which is composed of the spatial pattern of salt fields in northern China. The spatial pattern of salt fields in the southern coast of Yingkou City changed significantly due to large-scale human exploitation. The shrinkage intensity of the area of salt fields composed of salt fields such as tidal basin and evaporation pool was 13.67% 8.08, while that of non-salt field types such as grassland and construction land was -10.27 ~ 25.41 respectively.
