中文摘要：在浙江省10万km^2的区域内，选取32个典型样地调查杉木生态公益林凋落物特征。研究表明：1）幼龄、中龄、成熟林3个年龄级的优势林年均凋落量依次为56．2、121．5和327．2g·m^-2a^-1，在浙西北、浙中、浙南及沿海4个地理气候区域间无显著差异（P〉0．05）；2）叶凋落量占总凋落量的76．0％。96．4％；不同龄级的凋落物组分不同，即杉木在不同发育阶段凋落物存在差异；3）杉木优势林的凋落量小于含杉木的混交林，即乔木种类越多，杉木优势度越小，凋落量越多；4）凋落物对森林水源涵养和水土保持有重要作用。从凋落物角度分析，杉木优势林的生态效益较低，不利于林地自肥、保水及进一步的植被恢复。

外文摘要：Thirty-two sampling plots of ecological public-welfare forest that distributed in fourteen counties were investigated in over 100 000 km^2 zones of Zhejiang Province. Five quadrats were set in every plot by using diagonal method. From March 2000 to March 2001, litters were collected and analyzed every month. The results showed： In juvenile, middle-aged and mature stands Chinese Fir as the dominant species, the average annual litter productions was 56.2, 121.5 and 327.2 g·m^-2a^-1 respectively. There was no significant difference at annual litter among Northwest, Middle, South and seaboard region of Zhejiang Province （p 〉 0.05）. The production ratio of the defoliation to the total litter was about 76.0% - 96.4%, The litter component varied in distinct aged stands. The litter production of Chinese Fir dominance forest was less than that in mixed forest containing Chinese Fir; the more the species of arbor, the less the dominance of Chinese Fir, and the more the litter production. Chinese Fir dominance forest was not benefit on soil self-fertilization, keeping water and vegetation restoration deeply.
