<正>采用"3S"技术与地面调查相结合的方法对广西红树林的空间分布和林分结构进行全面的调查,并以行政区域为单元,从资源管理的角度对红树林分布、群落类型结构,以及林分覆盖度、树高等林分结构特征进行分析和评价。结果表明,广西的红树林在整个海岸带上的分布较为均匀,74.4%的红树林分布于海堤外侧,桐花树群落、白骨壤群落、秋茄-桐花树群落和白骨壤+桐花树群落为优势群落,61.9%的红树林覆盖度大于70%,78.1%的红树林平均高度小于2.0m。

An inventory for mangrove was carried through with combining remote sensing(RS),geographic information system(GIS),global positioning system(GPS) and fields investigation together in 2001 in the coast of Guangxi,western Beibu gulf.This paper deals with the distribution,community type structure and forest structure,such as crown density,tree height grade,etc.,regarding administrative division as the unit.The results indicate that the mangroves are distributed equably along the coast in a general way,74.4% of mangroves are location before the seadike,Aegiceras corniculatum,Avicennia marina,Kandelia candel,Aegiceras corniculatum and Avicennia marina,Aegiceras corniculatum are the dominance communities,61.9% of their crown density are higher than 70%,and 78.1% of their average height is lower than 2.0 m.
