| 摘 要： | 在森林资源清查和动态监测中，一般要求能识别树种、在树种复杂时也要求识别到树种组。成图时要求可直接使用几何精度高、类型边界清晰的中比例尺如１：２．５万的影像图。为了满足生产的需要，我们进行了遥感信息复合、遥感与非遥感信息复合及复合方法等实用技术应用的研究。实验中应用了ＭＳＳ与ＴＭ卫星图像、ＴＭ不同时相的图像、ＴＭ与Ｓｐｏｔ的复合，及复合前后信息特征变化的定量分析等研究。从而为最优波段组合、特征信息提取方法提供了基础。在动态分析中主要进行了采伐迹地、林墙、迹地更新等方面的测定，并对测定精度进行了评估。

| Abstract: | In the investigation of forest resources and dvnamic monitoring,it isgenerally required to distinguish tree species.If the species are complicated,it iSalso required to distinguish the species groups with similar biological characteristics.In drawing the maps it is required to have great geometric accuracy.The mediumscale image with distinct type border(for example,the image of 1/25000)can becomposed and drawn directly.To meet the needs of the investigation of forest re-sources and dynamic monitoring,we conducted the study on information compound. It includ 5 the study on the practical techniques of remote sensing information com-pound,remote sensing and non-remote-sensing information compounds,applicationof auxiliary information,compound method,etc.In experiments,we used the studiesof the satellite images of MSS and TM,the images of different temporal images ofTM,the compound of TM and SPOT,the quantitative analysis of the characteristicchanges of information before and after compound,etc.Thus provide basis for op-timum wave-band combination and the method of extracting characteristic informa-tion,and also provide the best satellite images of 1/25000 on more than 500 thou-sand hectares of and for the investigation of forest resources in the region of BaiLong Jiang River to conduct the second type of the investigation of forest resour-ces.In the analysis of dynamic monitoring,the following land type were mainlydetermined:cut-over land, forest wall and regeneration of cut-over land, etc.;theassessment Of accuracy of determination was also conducted. |
