1) 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。
2) 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
3) earth-rock mountainous area
北方土石山区
1.
The study is an attempt to explore the comprehensive eco-economic management model of soil and water conservation in the earth-rock mountainous areas of Northern China.
结果表明,通过对流域进行水土保持生态经济型综合模式治理,将流域治理,区域特色,市场推动有机结合起来,不仅使区域生态环境得到了进一步改善,水土流失得到了有效控制,而且带动了区域经济发展,为我国北方土石山区水土保持生态经济型综合治理模式探索提供了技术支持。
4) 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。
