摘要
选取毛乌素沙地东北部的伊金霍洛旗为研究区域,以少量野外定位调查数据与其对应的遥感信息和GIS信息为基础,利用岭估计分析方法,对影响生物量估测的遥感因子和GIS因子进行了筛选优化。找出了影响生物量估测的主要因子,建立了以像元为单位的生物量估测模型,实现了区域性生物量定量估测与自动制图。
The study area was chosen in Yijinholo County, Mu Us Sandland, by means of ridge estimation method. The factors affecting biomass were optimized and filtrated according to the orientation investigation data in field and the corresponding RS and G1S information. The main factors were found out, the biomass estimation model are set up, and the quantitative estimation of regional biomass and automation of cartography were fulfilled, which provides the scientific base to establish regional development plan and desertification combating plan.
