Coarse woody debris(CWD)is an important component in forest ecosystems and has a significant contribution to the maintenance of forest ecosystem health.A total of 17 plots each with 20 m×20 m in size were typically located and sampled throughout the Fenglin National Nature Reserve.Storage,diameter,length,and decay rank of CWD in broadleaved-Korean pine forest were investigated.The results are as follows.(1)The CWD storage of broadleaved-Korean pine forest amounted to 75.61 m3·hm-2,of which down logs,snags,stumps were 66.24 m3·hm-2,2.03 m3·hm-2,and 7.34 m3·hm-2,respectively.(2)The dominant diameter classes of down logs and snags were 11-20 cm(46%,of total CWD in quantity) and 0-10 cm(45%),respectively;the dominant length classes of down logs and snags were 0-5 m(66%) and 6-10 m(49%),respectively.(3)The distribution of decay classes of CWD presented approximately normal distribution,and mainly concentrated on classes Ⅱ(28%),Ⅲ(35%),and Ⅳ(26%).
