摘要:
利用2015年广东省第2次全国土地调查所用的遥感数据和地理地形资料,基本查明了2015年广东省海岸线与红树林分布现状.2015年,广东省大陆海岸线总长度为3829.91 km,其中人工海岸线、沙砾质海岸线、基岩海岸线、生物海岸线和淤泥质海岸线分别占大陆海岸线总长度的54.36%,15.24%,14.64%,8.57%和7.19%.珠海、深圳、汕头、湛江和汕尾的海岸线系数最高,相关开发利用程度较高,而广州、江门、茂名、揭阳、潮州和惠州等的海岸线系数低于全省平均水平,相关的海洋资源开发活动仍存在提升的空间;全省红树林总面积12586.56 hm2,主要分布在潮州、汕头、惠州、深圳、东莞、广州、中山、珠海、江门、阳江、茂名和湛江等地,红树林的相关规划与保护工作亟需加强.
Abstract:
Based on large quantities of remote sensing data obtained in 2015 and topographic data, the authors studied the distribution of different types of shorelines and mangrove wetland. In general, the results show the total length of the mainland shoreline in Guangdong Province was 3829 . 91 km in 2015 . The length of the artificial shoreline, gravel coast, rocky coast, biological coast and muddy coast accounted for 54. 36%, 15. 24%, 14. 64%, 8. 57% and 7. 19% of the total length of the mainland shoreline, respectively. Coastline coefficient of Zhuhai, Shenzhen, Shantou, Zhanjiang and Shanwei which have a highest development is higher than other cities in Guangdong Province. Coastline coefficient of Guangzhou, Jiangmen, Maoming, Jieyang, Chaozhou and Huizhou which still have the very big promotions was lower than the average of the whole province. The area of the mangrove wetlands is 12586. 56 hm2 . The mangrove wetlands are mainly distributed in Chaozhou, Shantou, Huizhou, Shenzhen, Dongguan, Guangzhou, Zhongshan, Zhuhai, Jiangmen, Yangjiang, Maoming and Zhanjiang. The data for mangrove wetland ecological protection and restoration provide important information.
