摘要: 土壤呼吸分为自养型呼吸(根呼吸)和异养型呼吸(微生物和动物呼吸),区分各组分呼吸可了解在全球变化条件下土壤碳循环和碳平衡的动态.本文综述了3种主要区分自养呼吸和异养呼吸的方法:①组分法;②根去除法;③同位素法.其中同位素法对根和土壤的影响最小,是最可靠的一种方法;综合各方面考虑,根去除法是最切实可行的方法.

Abstract: Soil respiration can be divided into two components: autotrophic(root)respiration and heterotrophic(microbes and soil fauna)respiration. The separation of soil respiration will contribute to the understanding of soil carbon cycle and carbon balance under the condition of global change. Three primary methods have been reviewed to distinguish auto-versus heterotrophic soil respiration including:①components method; ②root exclusion method and ③ isotope method. The isotope method is the best with the least disturbance to soil and roots. Taking into account of all the factors, the root exclusion method will be the most practical in the future.
