福建建瓯山地红壤的物理化学特性

Research on Physical and Chemical Characteristics of Red Soil in Fujian Province Mountainous Areas

分析了福建省山地红壤的自然成土条件,研究了该区域红壤的物理利化学特性,指出该区红壤的机械组成以砂粒为主,容重较大、孔隙度较低,保水能力较小,土壤营养元素贫乏,进而分析了福建省山区生态系统物质生产中土壤的限制因素,探讨提高山地丘陵区生态系统生产力的途径.

This paper analyzes the physical formative conditions of red soil in Fujian mountainous area, examines the physical and chemical characteristics of red soil in this area, and points out that the mechanical composition of the soil takes sandy articles as its main component. Great density and lower porosity and capacity for keeping water, scarcity of soil nutrient, and the limits for sustainable development of' mountain ecosystem have been studied, with an exploration of the measures for improving material production capacity of mountain ecosystem.
