不同治理模式的红壤物理性质与渗透性能研究

A Study on Different Control Model for Soil Physical Properties and Infiltration Capacity of Red Soil

针对长汀县河田严重侵蚀地状况，采取4种不同模式进行治理试验，10年后对土壤物理性质和渗透性能进行研究，结果表明，不同治理模式对土壤物理性质和渗透性能影响大小为模式Ⅳ＞模式Ⅱ、Ⅲ＞模式Ⅰ，严重退化地（对照地Ⅰ、Ⅱ、Ⅲ）土壤物理性质极度恶化，土壤渗透性能相当差，采用生物措施与工程措施相结合，是改善南方严重退化红壤物理性质和木壤渗透性能良好渠道。

For taking four harness patterns, the red soil of serious erosion were harnessed in Hetian,Changting, Fujian, in 1982. The soil physical properties and soil infiltration capacity in different harness and control patterns were studied after ten years. Through fuzzy cluster analysis,the order of soil physical properties and infiltration capacity follows: Pattern Ⅳ＞ Pattern Ⅲ, Pattern Ⅱ＞Pattern Ⅰ． The soil physical properties were extremely exacerbated, soil infiltration capacity were very poor in seriously deteriorated soil (Control Ⅰ，Ⅱ, Ⅲ ). To make proper biological measures and essential supplementary mechanical harness measures is one of the effctive measures to improve red soil physical properties and infiltration capacity on serious degradation.
