本文在各种土壤调查报告和文献的基础上初步编绘了一份中国变性土及变性土性土壤分布图。这些土壤分布于十个不同的地区。参照《土壤系统分类制》(USDA,1975)的标准,变性土主要分布于河南西部的南阳盆地,淮北平原、山东半岛西部和北部平原,以及海南岛北部和雷州半岛等四个地区,而变性土性土壤则分布于其余六个地区。在长江流域各大潮盆地及其支流的粘重母质上,主要分布变性土性冲积潮新成土,它们地形上处于低洼地区,同时具水湿的土壤水分状况,因而不属于变性土。
Based on various soil survey reports and documents, this paper initially compiles a map of the soil profiles of China’s denatured and denaturalized soil. The soil is distributed in ten different areas. According to the standard of Soil Taxonomy (USDA, 1975), degenerated soil mainly distributes in four areas of Nanyang Basin, Huaibei Plain, Western and Northern Plains of Shandong Peninsula, northern Hainan Island and Leizhou Peninsula, Soil is distributed in the remaining six areas. The major alluvial alluvial tides in the Yangtze River basin and their tributaries are mainly composed of denuded alluvial tillage and newly formed soil. They are located in low-lying areas on the terrain and have wet soil moisture conditions, so they do not belong to the degenerated soil.
