本文根据国内外近10多年来,有关热带、亚热带土壤资源利用中出现的物理问题及其研究资料而进行了综述。指出该区虽具丰沛的水量、热量的有利自然因素,但由于雨量分配不匀、降雨强度大,极易破坏表土的结构而导致水土流失,并出现严重的季节性干旱威胁。土壤高温也是影响植物生长的障碍因子。因此,合理利用本区土壤资源,必须充分估计这些不利因素及研究对策。文中介绍了影响红壤生态环境的最主要的土壤物理问题及其管理。列举了近期国际上的研究重点。 This article reviews the physical problems in the utilization of tropical and subtropical soil resources and their research data in recent 10 years at home and abroad. It is pointed out that although the area is rich in natural resources such as water and heat, the area is prone to soil erosion due to uneven rainfall distribution and large rainfall intensity, which can easily destroy the structure of the topsoil and lead to serious seasonal drought threat. Soil temperature is also a hindrance to plant growth. Therefore, to make rational use of the soil resources in this area, we must fully estimate these unfavorable factors and research methods. The paper introduces the most important soil physical problems that affect the ecological environment of red soils and their management. Cited the recent international research priorities.
