青海云杉和华北落叶松混交林林地蒸散和水量平衡研究

Shuitu Baochi Xuebao, 2006
2004年5～10月．通过测定青海大通一块退耕地上17年生的青海云杉和华北落叶松混交林树木蒸腾速率的日变化、月变化动态规律以及树木蒸腾总面积来确定混交林的蒸腾量，根据植物的蒸腾量估算树木在生长季的耗水量，进而推算出林地蒸散和水量平衡。研究表明．青海云杉、华北落叶松混交林生长季林地总蒸散量为251.80mm，以林木的蒸发散为主，占总蒸散量的80％，占同期降雨量的58％；灌草蒸散占总蒸散的13％；而土壤蒸发仅为25．71mm，占总蒸散的7％。

温室表层土壤硝态氮运移的水、热耦合效应研究

Shuitu Baochi Xuebao, 2008
为了探讨温室作物生产水肥管理和温度环境对土壤NO3--N向表层迁移的影响,选用5 a的温室土壤样品进行土柱蒸发模拟试验,研究蒸发温度、土壤初始含水量、初始NO3--N含量及其耦合效应对温室土壤迁移速率及其垂直剖面分布的影响。试验结果表明:蒸发温度和土壤初始含水量明显影响NO3--N向土壤表层的迁移,并随蒸发温度和土壤初始含水量的增加而加强;通过正交回归分析得出影响NO3--N迁移速率的因素依次为初始含水量、蒸发温度以及温度与含水量的交互作用;土壤初始NO3--N含量以及它与蒸发温度 ...
