  • Revised Date: September 06, 2019
  • During March and April of 2016, litter from forest of Schima superba, Cyclobalanopsis glauca, Pinus massoniana and Cunninghamia lanceolata was collected in Qiandao Lake, Zhejiang province. It was air dried, put into litter bag with 10g each and placed in 3 sample plots with 20 m×20 m each to study litter decomposition and carbon change within 840 days. The results showed that litter decomposition rate was in the order of C glauca>S. superba>P. massoniana>C. lanceolata, and 95% of litter decomposed within 5.99-7.49 year. Decomposition rate of litter from S. superba and P. massoniana forest had characters of fast in the first and slow later, while that from C. glauca was relatively fast with three fast periods. The decomposition rate of litter from C. lanceolata forest had no evident change. The carbon content in litter of the four tree species decreased with decomposition duration, but that of S. superba, C. glauca and P. massoniana had lag phases during the whole process.
