报道了川东中高山地区人工草地红三叶、鸭茅凋落物的分解速率与气温和降水之间的关系，并建立了动态模型。分析结果表明，气温的升高和降水量的增大都有利于凋落物的分解；季节之间相对分解速率变化较大，７月份相当于３月份的１．５倍；年度相对分解速率波动不大，慢年相当于快年的９７％以上；而年度绝对分解率呈现越来越慢的趋势。据估计，分解９９．５％的凋落物红三叶和鸭茅分别需要２年和３年。
The relationship between litter decomposition rate and air temperature and precipitation of red clover and arborvitae in artificial grassland in the middle and high mountain area of eastern Sichuan was reported and a dynamic model was established. The results show that the increase of temperature and precipitation are beneficial to the litter decomposition; the relative decomposition rate of seasons varies greatly, which is 1.5 times of that of July; the annual relative decomposition rate is not fluctuated , Slow years is equivalent to more than 97% of fast years; while the annual absolute decomposition rate showed a more and more slow trend. It is estimated that the decomposition of 99.5% of the litter of red clover and cogongrass respectively takes 2 years and 3 years.
