森林生态系统健康评价现状及展望

Present Situation and Prospect of Forest Ecosystem Health Assessment

以森林生态系统健康评价的概念为出发点,从评价层次、评价指标、评价方法和评价标准等方面剖析森林健康评价的关键技术,综述国内外有关森林生态系统健康评价的研究进展,并分析当前研究中存在的问题,如指标体系不够完善、评价方法有待完善、评价标准主观性强、评价结果不准确等。今后森林生态系统健康评价研究的重点应着重于理论探索和方法完善方面,从研究健康机制入手,完善评价指标体系,改进评价的手段、方法和技术,确立不同区域主要森林类型的健康标准,为调控不健康的森林、保持森林健康状态、实现森林生态系统的可持续发展提供理论依据和技术支持。

Forest ecosystems are a foundation of existence and development of human society. Therefore,the forest ecosystem health assessment is an important issue. This paper reviewed recent progress in the study on the assessment technology of forest ecosystem health from scale,indices,methods and standards. Then the paper analyzed the existing problems in present research. For example,the assessment indices are not comprehensive,the methods need to be improved,the standard is too subjective and the assessment result is inaccurate,etc. Therefore,the future research on forest ecosystem health assessment should be focused on theory exploration and research method improvement. First of all,the forest health mechanism needs to be understood more. And then assessment indices,means,methods and techniques should be improved to make the results more practicable. The health standards should be established for mainly forest vegetation in various areas. A comprehensive health assessment system for forest ecosystems should be developed aiming to supply bases for adjusting unhealthy forest,maintaining healthy forests and developing sustainable forestry.
