以广西省凭祥市青山实验林场为研究对象,基于等高线和二类调查小班数据,通过地理信息系统的空间分析,完成了生态土地类型(ELT)和生态土地类型相(ELTP)两个等级的分类和制图,构成了生态分类系统(ECS)等级结构中的两个最低层次。ELT包含环境信息,可以为森林经营提供依据;ELTP既包含ELT中的环境信息,又包含植被图层的植被信息,可以为森林经营区划和小班界限调整提供依据。
Taking the Qingshan Experimental Forest Farm in Pingxiang City, Guangxi Province as the research object, based on the contour lines and the data of the second type of survey, two types of ecological land type (ELT) and ecological land type phase (ELTP) were completed through spatial analysis of geographic information system The classification and mapping of grades constitute the two lowest levels in the hierarchy of ecological classification systems (ECS). ELT contains environmental information, which can provide the basis for forest management. ELTP contains the environmental information in ELT as well as the vegetation information of vegetation layer, which can provide the basis for the division of forest management and the adjustment of small class boundaries.
