1988-2005年三江源草地产草量变化动态分析

, 2010
三江源地区是我国长江、黄河、澜沧江的发源地,分析该地区草地生产力的变化动态,探讨导致草地生态系统变化的自然和人文驱动机制,对于制定科学的草地恢复、管理和利用战略,以及开展有效的生态工程成效评估具有重要意义。利用GLOPEM模型对三江源地区1988-2005年的草地产草量变化动态进行分析,结果表明:三江源地区草地生产力呈现出3-5年的周期性波动规律,其产草量的年际变幅表现出从东部地区到西部地区依次增高;从沼泽草地、高寒草甸、高寒草原到温性草原依次增高的特征。同时,18年来三江源地区草地产草量总体呈增加趋势,

三江平原典型草甸小叶章湿地土壤的反硝化作用

, 2009
选择三江平原典型草甸小叶章湿地土壤(草甸沼泽土)为研究对象,采用厌氧淹水培养法,研究了不同土层的反硝化率、反硝化能力及反硝化速率。结果表明,不同土层的反硝化率均随培养时间延长而增加,0～30cm土层的反硝化率较高,30cm以下土层较低且相近;不同土层的氮损失贡献率在不同阶段具有明显的时空分异特征,0～30cm土层的氮损失贡献率较高,介于52.39%和57.91%之间;不同土层的反硝化速率与培养时间均符合一阶指数衰减模型(R2≥0.97),上层土壤的反硝化速率明显高于下层土壤 ...
