| 摘 要： | 基于植物生态学原理,在设置样地、建立样方的基础上,分别采用角规法对三江源区10个典型乔木林样地蓄积量、每木检尺法对三江源区10个典型灌木林样地生物量、收获法对三江源区10个典型草本样地生物量进行年度连续监测,在同期、同空间、同尺度条件下发现:2006年度乔木林蓄积量相比2005年稍有增长,2006年度灌木林生物量相比2005年有增有减,2006年度草本生物量相比2005年均有减少。分析其原因主要是由于气候变化造成的,2006年较2005年平均气温升高0.2-1.0℃、蒸发量增加54-334mm、年降水量减少60.7-164.5mm。

| Abstract: | Based on the ecology theory,the forest stand volume of 10 typical sampling sites,shrub forest biomass of 10 typical sampling sites and herb biomass of 10 typical sampling sites were continuously monitored using relative methods.The results indicated that quantity of forest stands volume in 2006 was presented growth trend than that in 2005,shrub biomass was no obvious change than that in 2005,and herb biomass in 2006 was presented reduction trend than that in 2005.Climate change was the main reason.The avera... |
