中文摘要山地土壤泛指其形成环境和历史演变过程以山地和丘陵为背景的土壤。我国的山地丘陵区存在着丰富的土壤资源,它们不仅直接养育了这些地区的居民,还为城市和平原居民、为工业提供了大量动植物资源。我国天然森林资源的主体是由山地土壤抚育的,山地土壤系统的稳定更是维系山地丘陵本身和各种级别的流域生态平衡和环境优美的枢纽。因此,山地土壤开发是具有重要理论和实践意义的课题。
英文摘要 Mountain soil is generally referred to as slope soil forming and dcveloping on inclining basis in mountains and hills. Therefore, its essential feature different from plain soil is that soil development is strongly influenced by dynamic process of slope matter and its basis. In China, mountains ( including hills ) are widely distributed , with abundant soil resource, and they are of great value to agricultural economy.First, the author deals with over three basic characteristics ofmountain soil——the vertical differentiations of soil types, the fragilityof pedoecosystem, and the lateral migration of nutri雗t elements in soil which is not alike to vertical movement of that in plain soil.Then several theoretical questions concerned with mountain soil exploitation are discussed, including its definition, the relationship and difference with land use, and the impaction on mountain environment, as well as the relation to succession of soil fertility.Finally, pointing to the present situation and the problems of mountain soil exploitation, some exploiting principles are proposed. And based on varying horizonal natural zonation and structure of vertical zonal spectra of mountain soils, the author suggests to divide mountain soils in China into O exploitation-regions.
