摘要
以新疆天山西部的蒙玛拉林场为研究区,通过典型地物光谱分析,建立了中巴资源卫星02星CCD数据的森林资源遥感解译标志,并以此为依据,采用人机交互的目视解译技术,结合野外调查,提取生态公益林信息。结果表明:蒙玛拉林场的生态公益林总面积为2.8378×104hm2。其中,重点公益林为0.8948×104hm2,占生态公益林总面积的31.53%;山区国有公益林为1.9430×104hm2,占生态公益林总面积的68.47%。通过此次研究,证明中巴资源卫星02星CCD数据在森林资源调查等应用中,具有经济实用等特点,可用于县级、州级、省级等中大尺度区域的森林资源调查监测工作。
Non-commercial forest is important to make great ecological benefit and improve ecological environment. It has significant ecological value. In this study, Mengmala forest farm was selected as the study area. Interpretation symbols of forest resources in CBERS-02 CCD data were firstly established through analyzing spectral response characteristics of typical land surface objects. Then, according to these symbols, information of non-commercial forest was extracted from CCD data by combining interactive person-machine visual interpretation and filed investigation. The results show that the total area of non-com- mercial forest in Mengmala is 2. 8378 7（ 104hm^2, in which 31.53 % is key protected non-commercial forest, and 68.47 M is general protected non-commercial forest. Finally, it is proved that CBERS-02 CCD data can be used in regional forest resources inventory and monitoring on large and moderate scales.
