森林植被蒸散耗水测定方法研究进展

Research Progress on the Method of Determining Water Consumption of Forest Vegetation

森林蒸散是森林生态系统水分循环最重要的环节之一,对于森林水资源合理利用有重大意义。目前,测定森林蒸散的方法有很多,主要分为实测法和估算法。文章从组织器官尺度、单株尺度、林分尺度、区域尺度4个方面简述了每种方法的优劣及适应范围和使用条件。并且指目前森林蒸散研究存在的问题和发展趋势。旨在为森林水分循环、水资源利用、植被生态恢复、森林生态系统健康评价和维护提供研究基础。

Forest evapotranspiration is one of the most important aspects of water cycle of forest ecosystem, which is of great significance to the rational utilization of forest water resources. At present, there are many methods to measure forest evapotranspiration, which are mainly divided into actual measurement methods and estimation methods. In this paper, the advantages and disadvantages of each method and the application conditions and the conditions of use were summarized from the aspects of organization and organ scale, individual scale, stand scale and regional scale. The existing problems and development trend of forest evapotranspiration research were pointed out. This paper aimed to provide the research foundation for forest water cyelization, water resources utilization, vegetation ecological restoration, forest ecosystem health evaluation and maintenance.
