本文描述了研究区吉林省东部山区的地文景观特点和自然植被状况,阐述了生态土地分类的定义、基本特点及发展。根据研究区的地形图和卫片结合试点的劲松林场480个样点植被现状的调查数据,探讨了基于坡度、坡向、植被和海拔的四个分类因素下的5类和15类生态土地类型图。生态分类系统是确定、描述和绘制生态系统类型图的方法。本文研究是生态分类系统在吉林省东部针阔混交林区试验应用的一部分。图5表1参14。 This paper describes the landscape features and the status of natural vegetation in the eastern mountainous area of ​​Jilin Province in the study area, and elaborates the definition, basic characteristics and development of ecological land classification. According to the survey data of the topography of 480 sites in Jinsong Forest Farm in the pilot area combined with the patch experiment, five types and 15 types of ecological land under the four classification factors of slope, aspect, vegetation and altitude were discussed. Figure Ecological classification system is to determine, describe and draw the ecosystem type map method. This study is a part of the application of ecological classification system in the coniferous and broad-leaved mixed forest in eastern Jilin Province. Figure 5 Table 1 reference 14.
