一、前言地球资源卫星发射以来,由于其提供信息有宏观、快速、多谱段、多时相等特点而引起了人们高度重视,众多学者围绕其所提供的MSS资料的应用进行了多方面的试验研究工作,积累了大量经验,并且取得了一些可喜成果,但是,由于MSS资料的分辨率问题,在林业资源调查中并没有获得明显的突破,相当多的研究成果处于潜生产力的研究阶段,使其实际应用受到了限制。 I. INTRODUCTION Since the launch of the Earth Resources Satellite, people have paid great attention because of the macroscopic, rapid, multi-spectral and multi-temporal characteristics of the information provided. Many scholars have conducted many experiments on the application of the MSS data provided by them Work has accumulated a lot of experience and achieved some gratifying results. However, due to the resolution of MSS data, no significant breakthrough has been made in the forestry resources survey, and quite a lot of research results are in the research stage of potential productivity so that Practical application has been limited.
