黄土高原人工林地土壤水分亏缺研究

Soil Moisture Deficit in Artificial Forest Land in Loess Plateau

在乔木植被类型中，人工林地的土壤呼吸强度大于行道绿地。

Among arbor vegetation type , artificial forest land breathe intensity greater than Pavement green land .

用静态封闭箱式技术原位测定了西山地区元宝枫和油松两种人工林地土壤N2O的排放通量，表明该地区森林土壤为大气N2O气体一个重要的源。

The soil N_2O emission flux in the plantation of Acer truncatum and Piuns tabuleaformus woodland was measured in situ using static closed chamber technique .

茶园土壤动物群落的蜱螨目／弹尾目值介于1.83-4.53，均高于人工林地且差异显著（P0.05）。

The ratio of Acarina / Collembola in the tea plantation was lies between 1.83-4.53 , which was significant higher than that in the artificial plantation ( P0.05 ) .

即使不同类型的人工林地和园地之间，0~20cm和0~100cm土壤有机C的密度差异也可达到1.0kg/m2和3.5kg/m2。

Differences also existed in organic C density being 1.0kg/m2 and 3.5kg/m2 between different types of artificial forests and orchards .

草地2～4m深处土壤含水量平均值为13.2%左右，含水量明显较人工林地高，无土壤干化的显示。

The average soil moisture content in depth of 2 ~ 4m under the grasslands is 13.2 % and is significantly higher than that under the artificial forests .

结果表明：杉木人工林地土壤含水量为404.4mm，土壤贮水能力达1220t／hm2，年径流量474.1mm，洪峰径流系数0.19。

Results showed that average soil water content , soil water storage capacity , yearly runoff , runoff coefficient of flood peak in Chinese fir plantation were 404.4 mm , 1 220 t / hm 2,474.1 mm , 0.19 respectively .

本研究采用静态封闭箱式技术在1997～1998年对北京西山低山区元宝枫和油松人工林地土壤中N2O的排放通量进行了原位测定。

The soil N 2O emission flux in the plantation of Acer truncatum and Pinus tabulaeformis woodland was measured in situ using static closed chamber technique at the year of 1997 ~ 1998 in Xishan area , Beijing , China .

杉木（Cunninghamialanceolata）是我国南方最重要的造林树种，但随着杉木栽培面积和连栽代数的不断增加，杉木人工林地力衰退日趋严重。

Chinese fir ( Cunninghamia lanceolata ( Lamb . ) Hook ) is the most important plantation tree species in South China However , yield decline and soil degradation have widely occurred in Chinese fir stands with the increasing of plantation areas and generations .

本文对大青山阴坡中部油松人工林地土壤水分、物理特性及林冠截留等进行了研究，主要研究结果如下：（1）林地土层厚度为35cm～104cm。

The soil water characteristics , the soil physical characteristics and the canopy interception of Pinus tabulaeformis plantation were studied in the middle shady slope of Daqing Mountain . The results showed that : ( 1 ) The thickness of the soil layer was 35 ~ 104cm .
