摘要
通过对南瓮河自然保护区落叶松林、白桦林和草地内3种枯落物含水率的测定,确定其年变化规律,直观认识枯落物含水率变化原因。结果表明:5月和10—11月枯落物含水率较低,极为干燥;7—8月枯落物含水率较高,湿度较大;阔叶林枯落物含水率较高,针叶林地枯落物含水率次之,草地枯落物含水率较低。
Through determination of moisture content of three kinds of litter in Larixspp.,Betula platyphylla & meadow,their annual variation were determined;the reasons for changes in the moisture content of litters were understood intuitively.Result shows that:the moisture content of litters is lower and extremely dry in May,from October-November;the moisture content of litters is higher and wet from July to August.The order of moisture content of litter is broadleaf forests>coniferous woodland>meadow.
