摘要： 论文研究了“3S”技术与地面调查相结合进行红树林资源调查的技术方法。以SPOT和Landsat7ETM+为信息源,经预处理后在GIS支持下进行目视判读和编制工作手图,实地采用GPS实测和目测勾绘修正小班界线,进入林内调查林况因子。结果表明,群落类型调查精度为100%;小班面积平均误差、小班周界平均位移、小班中心位置平均相对位移分别为11.8%、18.3m、13.1%,远小于常规方法(1∶10000地形图目测勾绘)的76.6%、108.7m和274.9%;效率比GPS实测高2.04倍,有效地解决了传统方法调查中存在的红树林空间位置和分布境界线定位准确性差、面积精度低,一般航天遥感调查分类精度低和GPS方法效率低等问题。

Abstract: In this paper,the method of mangrove inventory combined"3S"with ground invento-ry was studied.Through adopting a series of technological methods including image processing,visual interpretation and mangrove mapping,in-situ checking and correcting the boundary line of the sub-compartment of the map,woods condition factor inventory and GIS space analysis,a number of technological problems have been solved effectively and a kind of scientific method for mangrove inventory has been advanced.These technological problems include that the low area precision and inadequate accuracy of the spatial position localization of the general method,low classification precision of remote sensing,and the low efficiency and the great labor intensity of the method of GPS.

Key words: mangrove, inventory, remote sensing(RS), geographic information system(GIS), glob-al positioning system(GPS)
