摘要
采用遥感技术对最新卫星图象数据进行解译,分类统计广东全省湿地面积。结果表明,广东湿地类型丰富, 有五类20型,包括了中国湿地所有的类、80%的型;湿地总面积1864 101.3 hm2,占广东陆地总面积的10.4%,高于全国和全世界的相关比例。同时近海近岸湿地面积有1 081988.3 hm2,占全省湿地总面积的58.04%,显示了广东是海洋大省的特征。此外,广东湿地分布有丰富的湿地植物,湿地动物和湿地鱼类以及众多珍稀濒危和国家保护物种,显示出保护广东湿地的迫切性和重要性。
The remote sensing technology was employed to investigate the types and the area of Guangdong wetlands. The results showed that: types of Guangdong wetlands were very rich. There are 5 types and 20 subtypes of wetlands, including all of the types and 80% subtypes of the wetlands in our country. The total area of Guangdong wetland was 1 864 101.3 hm^2, making up 10.4% of the total land area of Guangdong Province. At the same time, the coast wetland area was 1081988.3hm^2, making up 58.04% of the total area of Guang dong wetland. Furthermore, there are plenty of wild life in the wetland, and many are the species of rare and in danger. Therefore, conservation of wetlands in Guangdong is very urgent and important.
