摘要
广东是我国红树林分布最多的省份之一,有红树植物17科31种,红树林湿地面积21 438.3 hm2,主要分布在粤西,其次是珠江三角洲地区。红树林具有防灾减灾、净化环境、调节区域小气候、保护生物多样性等重要生态功能。在广东林业生态省建设中,保护和发展红树林被列为八大林业生态工程之一。本文对红树林的生态功能进行了具体分析;阐述了广东红树林资源分布现状、红树林在广东林业生态省建设中的作用以及保护、发展状况;指出目前红树林还面临围海造田、围海养殖、沿海城市化、废水污染等威胁,红树林保护任务艰巨;并就加强红树林保护提出建议。
Guangdong is one of the provinces with the most mangrove resources in China.
