中国南方雨雪冰冻灾害受损森林植被研究进展

2008年年初我国南方遭受了一场极为罕见的大范围持续低温雨雪冰冻极端气候灾害,这场灾害给我国人民的生产生活造成了重大损失,其中,林业受损尤为严重。我国学者针对受损森林生态系统进行了多方面的调查与研究。对现有的调查研究工作进行综述,重点概述了森林结构、功能和经济效益的受损状况,总结了天气条件、地理因素、树种及其生长情况,分析了林分特征等方面的森林受损机制以及受损森林的恢复与重建对策,对现有的研究在内容、水平及方向上的不足之处提出建议,以期对未来的相关研究提供帮助。

A review of freezing rain and snow impacts on forests in southern China

An unusually severe freezing rain and snow disaster of continuous low temperature covered a wide range of southern China in early 2008. This caused significant loss to human’s work and life, especially on forests. There are many studies focusing on damaged forest ecosystems. This research project searched out and summarized all the relevant research information about the effects of freezing rain and snow disasters on forests, to discuss the connection between damage impacts and the elements of weather sever-ity, site conditions, tree characteristics and stand characteristics. The project also researched the recovery and reconstruction rates of forests from freezing rain and snow disasters. Compared to existing researches, we found their shortages on depth and orientation. Then the article put forward several recommendations to help with future research.
