土壤普查和分类是制订农业区划的必要条件。对某区域内形形色色的土壤个体,按照一定原则进行分类,可以为合理利用土壤,提高土壤肥力,综合发展农、林、牧业生产提供依据。为此,我们从1979年起,对上海土壤的分类进行了研究,并得到市、县许多土肥工作者的指导和帮助。现把研究结果总结如下。一、上海土壤分类概况我国开展土壤分类研究较迟,解放前受美国土壤分类学派影响较大,解放后又转学苏联。1959年全国土壤普查后,结合国情,开展了土壤分类研究。我国的土壤分类,比较重视耕作土壤的发生、分类、命名的研究。
Soil census and classification are necessary conditions for the formulation of agricultural zoning. The classification of soil individuals of all kinds in a certain area according to a certain principle can provide the basis for rational use of soil, improvement of soil fertility and comprehensive development of agriculture, forestry and animal husbandry. To this end, we have studied the classification of soils in Shanghai since 1979 and have been instructed and helped by many land-fertilizers workers in cities and counties. The research results are summarized below. First, Shanghai soil classification profile China carried out soil classification study later, before liberation by the United States soil taxonomy more influential, after the liberation and transfer to the Soviet Union. After the 1959 National Soil Survey, combined with national conditions, carried out soil classification studies. China’s soil classification, pay more attention to the occurrence of farming soil, classification, naming of the study.
