摘要

通过对研究区12种不同土地利用类型土壤容水量和渗水率的试验研究

分析了相同土地利用和不同土地利用方式下土壤容水量和渗水率的差异。结果表明

相同土地利用方式下

农坡地土壤容水量差异约1倍

差异较大;旱梯田土壤容水量差异可达35.23%

差异明显;荒坡地相差仅为5.84%

差异较小;沟台地差异不明显。不同土地利用方式下

土壤入渗性能差异显著。在连续入渗180min时

YL(人工杨树林地)、HF(荒地整地后封管1a自然草地)、NT(人工柠条林)、SJ(人工沙棘林)、YS(人工油松林)、ZK(针阔混交林)土壤容水量分别是HP(荒地)的108.19%

173.43%

157.76%

192.28%

93.64%和129.67%。沙棘林、柠条林等人工灌木林地的土壤容水量大于人工乔木林地。荒坡经过隔坡水平台整地封闭保护自然恢复植被1a后

土壤容水量高于多数乔、灌木林地

是一种经济有效的水土保持措施。土壤容重是影响土壤容水量的主要土壤物理特性指标

土壤容重越大

土壤容水量越小。土壤含水率在9.60%～19.02%范围内对土壤容水量的影响不明显。

Abstract

The paper focused on soil infiltration rate and soil moisture content under 12 different land uses in semiarid region of loess.The results showed that soil moisture content was about twice under the same land uses in the farmland-sloping

which was significant difference.The gap was about 35.23% in the drought terrace

5.84% in the hillsides

no obvious difference was found in the ditch platform.Artificial vegetation played an obvious role in improving soil moisture content.When infiltration continued 180 minutes

contrast to unculivated land the soil moisture content of Poplar plantation

enclosed grassland

Caragana plantation

Seabuckthorn plantation

Plnus plantation

mixed plantation was 108.19%

173.43%

157.76%

192.28%

93.64%

129.67% respectively.Soil moisture content in the artificial shrub lands

such as seabuckthorn forests

caragana lin

was larger than artificial arboreal lands.The way of plough in hillsides was an effective measure in soil and water conservation.Soil bulk density acted as an active index affected soil moisture content

which soil bulk density was bigger

soil moisture content was smaller.Soil infiltration rate was 9.60%~19.02%

which would not affect soil moisture content.
