土圈与土资源

本文提出了土圈(Sesosphere)与土资源(Sesotic Resource)的概念。认为在自然地理环境中,应该把岩石圈中的风化残积层和第四系松散堆积层(Sediment)从基岩中划分出来;把生物圈中的土壤(Soil)划分山来。将Sediment和Soil归并作为土圈,各取字首两字母Seso-对应中文的“土”。文中还提出了计算土资源的一些定量指标。

SESOSPHERE AND SESOTIC RESOURCES

This paper has advanced a concept of sesosphere and sesotic resource. Themain idea is plus sediment and soil. The sediment is separated from lithosph-ere and the soil is separated from biosphere. Each takes two letters fromhead plus sphere, the word sesosphere is fromed. The environment is compo-sed of atmosphere, hydrosphere, biosphere, lithosphere and sesosphere. Theresources is composed of climatic resource, water resource biotic resource,mineral resource and sesotic resource. This paper has also discussed the sesomass which is about sesohorizondepth, sesohorizon area, mean annual sesohorizon erosion depth and antiero-sion years. And, it points out that sesotic resource is different from land re-source. The sesotic resource is a part of the land resource.
