热带地区再生资源航天感遥调查的研究

Research of Satellite Romote Sensing for Survey of Renewable Resources in Tropical Region

本文介绍了热带地区再生资源航天遥感调查的研究方法。该研究制定了适用于航天遥感调查的热带地区再生资源分类系统。采用了由VAX计算机和S600软件组成的IIS Model75图象处理系统,对新一代卫星数据(Landsat—TM_2、TM_3、TM_4;Spot—XS_1XS_2、XS_3)进行了几何校正,直方图均衡化和假彩色合成等处理。以森林生态学为导向,在地面抽样数据的支撑下,辅以特殊地段的航片对处理后的卫星影象进行半读分析。在此基础上,编制出了以森林资源为主体的再生资源分布图。不仅为西双版纳再生资源的保护和管理提供了重要的基础数据,而且还表明了航天遥感是进行热带地区再生资源调查的一种经济而有效的技术手段。

The research method of Satellite Remote Sening for survey of renewable resources in tropical region was indroduced and the classification system of the renewable resources in tropical region for survey with Romo-te Sensing technique was developed , Satellite data (LandsatTM2, TM3 TM4;Spot-Sj, XS1, XS3. ) were processed through geometric correction, histogram equaization and false color composite by using the II S model 75 with S600 software over a microVAX computer. On the basis of forest ecology, the ground sample data and aerial photograph in special sites, the processed satellite imagers were analysed and interpreted. And then the distribution map of renewable resources mainly consisting of forest resources was made. The research not only provided the important basic data for reservation and management of renewable resources in Xi-shuangbana, but also revealed that satellite remote sensing is an economic and efficient technique for survey of renewable resources in tropical region.
