摘　　要：为研究利用国产GF-1号卫星影像进行森林资源定量估测的可行性,本文选择我国东北大兴安岭地区某林业局为试验场地,采用GF-1号卫星影像16m分辨率的WFV多光谱数据,结合试验区域的一类样地调查资料,建立以样地为单位的森林蓄积量估测方程,进行森林蓄积量定量估测。为有效设置可能影响蓄积量估测的遥感信息,本文重点分析了遥感比值波段的设置和优选对蓄积量估测模型建立和估测精度等的影响规律。研究结果表明,设置不同种类的比值波段将影响最优变量筛选结果,高分遥感信息对提高森林蓄积量估测精度有较大影响。In order to study the feasibility of using domestic GF - l satellite images to quantitative estimate the forest resources, this paper select some Forestry Bureau in Greater Khingan Mountains area in Northeast China as the test site, using GF - 1 satellite images of 16m resolution WFV Multi -spectral data, combined with sample plot data of national continuous forest inventory, establishing the equation based on sample plot to estimate the forest stock volume. To effectively set up the remote sensing information which may affect the volume estimation, this paper analyzes the influence of the setting and optimum selection of the remote sensing ratio band on the establishment of the stock estimation model and the accuracy of prediction accuracy. The research result indicates that the screening result of the optimum variable will be influenced when setting different kinds of remote sensing ratio band, The information of GF - 1 satellite image has a greater affection to increasing the precision of forest volume estimation.
