Studies on the methods of mangrove inventory based on RS,GPS and GIS
基于“3S”的红树林资源调查方法研究

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.
