红壤退化过程与生态位的研究

Degradation process of red soil and its niche.

应用生态位概念研究红壤退化和改良过程中的生物学特征及其与生态环境条件的关系，把红壤的生物学循环作为重点，分析红壤生态位的演化特点，探索红壤生态系统退化和重建的若干规律和描述方法。

The biological characteristics in degradation and remediation of red soil as well as its relationships with eco environmental conditions were discussed by using niche concept. With biological cycles as the focal point, the development feature of red soil niche was analysed, and the rules and descriptive methods for degradation and restoration of red soil ecosystems were investigated to establish the methods and indicators for evaluating the degradation of red soils.
