1) lithoid mountainous areas in North China
华北石质山区
1.
Plot-scale runoff generation model of lithoid mountainous areas in North China;
华北石质山区坡地产流模型
2) rocky mountain area of northern China
华北土石山区
1.
By studying on the soil water of pine forests and bare soil of shady slope,and Platycladus orientalis and oak mixed forests of sunny slope in rocky mountain area of northern China,there was less illumination time and intensity in the shady slope than in the sunny slope,so the evaporation of shady slope was little,which was propitious to hold water and increase water in the soil.
通过对华北土石山区阴坡油松林、阴坡裸地和阳坡侧柏栎类混交林土壤水分研究可知,阴坡光照时间和强度较阳坡小,相应的林地蒸发散减少,有利于林地的蓄水,增加土壤的含水量。
3) mountainous area of North China
华北山区
1.
The mountainous area of North China is surrounded by the North China Plain, Shanxi Gansu Loess Plateau and Inner Mongolia Plateau.
华北山区位于华北平原与陕甘黄土高原以及内蒙古高原之间,是我国经济欠发达地区之一。
2.
Rainfall simulation on representative plots(5 m wide and 10 m long) in a mountainous area of North China was carried out to compare water discharge and recession characteristics by surface runoff,soil-layer flow and mantle rock flow.
通过位于北京市怀柔区东台沟的华北山区典型坡面径流场内人工模拟降雨实验,分别讨论了地表径流、壤中流和基岩风化带出流共3层的退水特征,三者比较结果表明,壤中流最早开始退水,其退水历时最长,流量最小;地表径流的退水一般受降雨和地形地貌的影响,雨停后迅速消退;基岩风化带出流通常在地表径流退水的后半段开始。
5) rocky mountain region
石质山区
1.
Water-holding capacity of litter layer for different forest was researched on rocky mountain region,in LaiWu City,Shandong province.
④在石质山区生态修复的林业工程中,应尽量增加针阔叶混交林分或阔叶林分的培育、减少针叶林分,以提高人工林分枯落物层在防止土壤侵蚀和涵养水源中的作用。
2.
Water-holding capacity of litter layer in different forest stands was restudiedhed on rocky mountain region of Liuzhuang small watershed, in Jining City, Shandong province.
在山东省济宁市石质山区刘庄小流域,对5种人工林分枯落物层涵蓄水分特征进行了观测。
