森林土壤研究几个方面的进展

Progress in Several Aspects of Researches on Forest Soils

文章从森林土壤组成、结构与功能一致性这个原理出发，论述了森林土壤物理性质、化学性质、生物化学活性以及森林土壤微生物等方面的研究进展，阐述了人类在有限的、可供利用的土地上维护和提高森林土壤生产力的途径。

Abstract In recent score years much progress has been made in theoretical researcheson forest soil science and in practical forest production. In macro field of soil study thesoil senesis , classification and a number of basic physical and chemical properties havebeen known. Now the study has developed into the micro field to reveal the constitutionand structure of forest soils , study the relation between soil constitution and structureand its function so that the forest soil resources can be rationally utilized. To start fromthe principle of conformity of soil constitution , structure , properties and function ,thepaper describes theprogress in researches on the physical and chemical properties , bio-chemical activity of forest soils and the soil microorganisms , and suggests the approachto maintain and protect the productivity of forest soils.
