| 摘 要： | 潟湖是重要的海岸湿地类型,具有丰富的自然资源和独特的生态功能。近几十年来,我国的海岸潟湖遭到了极大破坏,因此,开展我国海岸潟湖遥感监测与分析具有重要意义。本文根据1979年、1990年、2000年和2010年的4期共102景多时相遥感影像数据,利用遥感和地理信息系统等技术方法对我国大陆海岸潟湖进行了遥感监测,首次调查统计了我国大陆海岸潟湖的名称、数量、分布、岸线长度和面积信息,并对近31年来我国大陆海岸潟湖的变迁状况进行了分析。结果表明,1979年我国大陆海岸潟湖共计251个,近31年,共消失19个潟湖,其中辽宁省消失15个,广东省消失3个,广西壮族自治区消失1个;1979年我国大陆海岸潟湖岸线总长度为2 692.26km,总面积为1 092.805 5km2,至2010年我国大陆海岸潟湖岸线总长度共减少337.80km,潟湖总面积共减少204.103km2;31年间,我国大陆海岸潟湖的岸线长度和潟湖面积总体均处在持续减少的状态,各省(自治区)也基本符合该规律;1979-2010年间,我国大陆海岸潟湖大部分处在老年期,死亡期潟湖消失19个。

| Abstract: | The lagoon,one of the most important types of coastal wetlands,provides abundant natural resources and unique ecological functions. In recent years,coastal lagoons in China have been greatly damaged. Therefore,remote sensing monitoring and analysis of it is of great significance. According to a total of 102 scenes of multi-temporal remote sensing image data in 1979,1990,2000 and 2010,the paper monitored the coastal lagoons in the mainland of China with remote sensing and geographical information system techniques. The name,quantity,distribution,shoreline length and area information of coastal lagoons were surveyed for the first time. Also,the evolutions of coastal lagoons in mainland China in recent 31 years were analyzed. The results showed that,there were 251 coastal lagoons in mainland China in 1979,but a total of 19 lagoons disappeared in the last 31 years,among which are 15 of Liaoning province,3 of Guangdong Province and 1 of the Guangxi Autonomous Region; the total length of the shoreline and the area of the lagoons were 2 692.26 km and 1 092.805 5 km2 respectively in 1979,but both of them reduced by 337.80 km and 204.103 0 km2 during the period; the shoreline length and the lagoon area of China mainland were in decline overall,and the 5 provinces were basically in accordance with this law; from 1979 to 2010,most of the coastal lagoons in the mainland of China were in the old phase,and there were 19 lagoons lost in the death phase in the last 31 years. |
