长白山次生蒙古栎林细根生物量及其季节动态
Fine Roots Biomass and Seasonal Dynamics of Secondary Mongolian Oak Forestry in Changbai Mountain in China
摘要
Abstract
Fine roots biomass and seasonal dynamics of secondary Mongolian oak forestry were studied in Changbai Mountain.The results showed that the fine roots biomass increased gradually with changing of season and its range was from 4.023 3 t/hm2 to 4.916 3 t/hm2 from late April to late September.The rate of fine roots biomass of different soil layers indicted that the monthly fine roots biomass in 0-10 cm was 67.2%,but it was lower(59.3%)in late July.The biomass was the lowest in late April,and the changing trend of the living fine roots biomass in different layers was the similar to the total living fine root biomass.The annual production of growth,mortality and decomposition were 2.228 0 t/hm2,0.782 0 t/hm2 and 0.119 0 t/hm2 respectively in the forest.And the annual fine root turnover rate was 0.54 times per year.关键词
