| 摘 要： | 丁字湾地区是山东半岛蓝色经济区划9大核心区之一,是胶东经济圈一体化建设的焦点,发展远景广阔。本文选取2005年、2010年、2016年三期TM影像进行遥感解译研究丁字湾地区土地利用变化特征及其空间分布。研究结果表明,丁字湾地区土地利用类型以耕地为主,2005—2016年间建设用地、草地的面积显著增加,水域、海域面积大幅减少。土地的转移主要发生在"建设用地与耕地、耕地与水域、养殖盐田与海域、草地与养殖盐田"之间。城乡建设的不断发展,也给丁字湾地区带来了海岸侵蚀、海水入侵等生态环境负面影响。建议在湾口地区开展"退围还海、退养还滩、退耕还湿"等海岸整治修复工作后,发展人地环境和谐的生态旅游经济。

| Abstract: | Dingziwan area is not only one of the nine core areas of Shandong Peninsula blue economic division, but also the focus of Jiaodong economic circle integration construction with broad development prospects. In this paper, three TM images in 2005, 2010 and 2016 have been selected for remote sensing interpretation to study the characteristics and spatial distribution of land use change in Dingziwan area. It is showed that cultivated land is the main type of land use in Dingziwany area. From 2005 to 2016, the area of construction land and grassland have increased significantly, while the area of water area and sea area have decreased significantly. The transfer of land mainly occurs between "construction land and cultivated land, cultivated land and water area, cultivated salt field and sea area, grassland and cultivated salt field". The continuous development of urban and rural construction has also brought negative impacts on the ecological environment, such as coastal erosion and seawater intrusion. It is suggested that the eco-tourism economy with harmonious human and land environment should be developed after the coastal renovation and restoration work, such as "returning reclamation to sea, returning cultivation to beach, returning farmland to wet" in Wankou area. |
