森林土壤健康评价研究进展

Research Progress on the Assessment of Forest Soil Health

实施森林健康评价工作是促进林业可持续发展的最主要途径,森林土壤作为林木生长的基础,直接影响着森林的健康状态。综述森林土壤健康概念的形成过程,指出国内外不同专家对森林健康概念的不同定义。同时列举了森林健康评价体系中使用频率较高的评价指标和如形态特征指标、物理性质指标、化学性质指标、生物性质指标,并指出指标选取原则和几种最小指标集。国际上评价指标体系的方法较多,主要阐述了3种创新方法。最后根据现阶段我国森林土壤健康研究的不足提出研究方向。

The implementation of forest health evaluation is the main way of promoting the sustainable development of forestry. Forest soil as the foundation of forest growth has a direct impact on the health status of the forest. This paper reviews the formation of the concept of forest soil health,and points out that there are different definitions on the concept of forest health at home and abroad. Meanwhile,several commonly used indices in the forest health evaluation system,such as morphological indicators,physical properties indicators,and biological properties indicators,are enumerated. The principles of index selection and several minimum index sets are pointed out. Since there are many methods in constructing evaluation index system,three innovative methods are mainly described. Finally,based on the problems existed in the assessment of forest soil health,the research direction in the future is put forward.
