遥感技术在立地类型调查中应用的研究
APPLICATION OF REMOTE SENSING TECHNIQUES IN THE FOREST SITE SURVEY
【摘要】 在广西大桂山试验林区,收集地面实况,处理、判读遥感图象,从遥感图象上提取有关地形、植被、土壤及气候等立地信息,并将它们量化及主成分分析;采用排序法划分立地类型,编制航空象片数量化立地指数表及拟合产量预报模型,以评定立地质量,判读、转绘、编绘立地图。这些图、表的精度能满足生产要求。
【Abstract】 By applying remote sensing images, this paper develops a new method which deals with the classification and the mapping of forest site-types and provides confidential information for the activities of forest management. According to the verification of ground data, the accuracies of the quantization aerial photo site-index table for masson’s "pine, the predicted productivity model, maps and tables of site-types can meet the demands for application.
