森林是陆地生态系统的重要组成部分,在全球碳循环中起到重要的作用。森林固定的碳每年约占整个陆地生态系统的2/3,其变化决定了陆地生态系统碳源和碳汇的功能。目前,国内外众多学者对区域尺度森林碳储量的估算所提出的方法较多,但还没有统一的估算方法。样地查清法是估算森林碳储量的方法之一,通过总结该方法的优缺点及应用范围,为碳储量估算精度和碳评估提供合理的参考。
Forests are an important part of terrestrial ecosystems and play an important role in the global carbon cycle. Forest fixed carbon accounts for about two-thirds of the total terrestrial ecosystem each year, and its change determines the function of terrestrial ecosystem carbon sources and carbon sequestration. At present, many scholars at home and abroad have proposed more methods for estimating forest carbon stocks at the regional scale, but there is no unified method for estimating carbon stocks at the regional scale. One of the methods for estimating forest carbon storage is to find out the method of determining the amount of forest carbon storage. By summarizing the advantages and disadvantages of the method and its application scope, it provides a reasonable reference for the carbon estimation accuracy and carbon assessment.
