【摘要】：以營口市南部海岸為例,采用高空間分辨率衛(wèi)星遙感影像建立了沿海鹽田各組成部分的影像特征和面向?qū)ο蟮柠}田空間格局衛(wèi)星遙感影像信息提取技術(shù)流程,分析了沿海鹽田空間格局特征及其變化.結(jié)果表明:面向?qū)ο蟮母呖臻g分辨率衛(wèi)星遙感影像信息技術(shù)可以詳細(xì)地將沿海鹽田空間格局劃分為納潮池、蒸發(fā)池、初級制鹵池、中級制鹵池、高級制鹵池、結(jié)晶池和儲鹽池,以及養(yǎng)殖池、建設(shè)地、草地、坑塘濕地等非鹽田類型.我國北方區(qū)域鹽田空間格局組成的納潮池、蒸發(fā)池、制鹵池、結(jié)晶池、儲鹽池的面積基本比例為15∶45∶26∶4∶1.大規(guī)模的人類開發(fā)導(dǎo)致營口市南部海岸鹽田空間格局變化顯著,納潮池和蒸發(fā)池等鹽田組成池塘類型面積收縮強(qiáng)度分別為13.67、8.08,而草地、建設(shè)地等非鹽田類型面積收縮強(qiáng)度分別為-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.
