Abstract

Recent advancements in soil digital mapping have opened new opportunities for handling the scientific and applied problems of ecological soil monitoring, inventory of land and soil resources, and are generally helpful in optimizing the management of natural resources. For Karelia the development of forest soil assessment techniques is essential, considering that 95% of the republic’s land is forest soils. This paper tells about the process of creating an updated digital map of forest soils fertility in Karelia, scale 1 : 500 000. To this end, the archival soil productivity map of the republic, produced in paper version by R.M. Morozova in 2000, was scanned and converted into a vector layer with the use of the MapInfo Professional 8.5 software package. The resultant layer was aligned with the existing digitalized soil map of Karelia, which served as the basis for constructing the thematic layer according to the data on the fertility of each soil type. As a result of this study, the soil fertility assessment scale was specified and the percentage ratio of soils of different productivity in Karelia was calculated. The digital soil fertility map is an important information source of archival and modern data, and also is a part of the GIS for soils of Karelia.
制作卡累利阿的数字土壤肥力图
土壤数字制图的最新进展为处理生态土壤监测、土地和土壤资源清查等科学和应用问题开辟了新的机遇,并普遍有助于优化自然资源管理。对于卡累利阿来说,森林土壤评估技术的发展至关重要,因为共和国95%的土地是森林土壤。本文讲述了创建卡累利阿森林土壤肥力更新数字地图的过程,比例尺为1:50 000。为此,在2000年由R.M. Morozova制作的纸质版本的共和国档案土壤生产力地图被扫描并使用MapInfo Professional 8.5软件包转换为矢量层。结果层与卡累利阿现有的数字化土壤图对齐,作为根据各土壤类型肥力数据构建专题层的基础。在此基础上,确定了土壤肥力评价尺度,计算了卡累利阿不同生产力土壤的百分比比例。数字土壤肥力图是档案和现代数据的重要信息源,也是卡累利阿土壤地理信息系统的组成部分。
