Whether rainy year or dry year,semiarid or subhumid region,the site evaporation account for a largeproportion in the total water consumption,transpiration next,crown interception and surface runoff smallest,butthe importance of artificial regulation is:evaporation＞runoff＞anspiration＞crown interception.

黄土高原人工林系统耗水量，无论丰水年或枯水年，均以林地蒸发耗水最大，其次为林木蒸腾、林冠截留，地表径流最小。其人工调控的重要性以林地土壤蒸发位居第一，地表径流远在林冠截留甚至林木蒸腾之上。

As the subsistence farming of loess plateau with frequent natural disasters such as drought and geographically is far away from the economic center. In recent years, it is very common in that country"s countryside that the labors earn life outside their hometown which leaves the problem of "the children-staying-in-local " education gradually serious. I profess in a countryside high school in Tongwei county and know that place"s situation thoroughly thus I gain the first-hand materials.

作为全国有名的贫困县，在经济上属于黄土高原自然农业经济，干旱等自然灾害高频发生，在地理上远离经济中心，近年来，当地农村劳动力外出务工的现象非常普遍，"留守子女"的受教育问题日益突出，本人任教于通渭县的一所农村完全中学，熟悉当地情况，能够获取第一手资料。

The subsoil settlement is one of the main research subjects in soil mechanics.

摘要地基沉降是土力学中的主要研究课题之一。黄土由于其特殊的结构性，一般在浸水与压力的作用下显示出不同程度的增湿变形。

In order to select a perfective procedure and protocol for the fine grain OSL dating, measurements of natural IRSL and GLSL signals from a range of modern sediment samples collected from different sedimentary environment, tests of IRSL and GLSL bleaching behaviors for loess fine grains under sunlamp, and comparisons of the equivalent dose determined by different methods have been undertaken, as well as IRSL and/or GLSL dating of more than forty sediments samples taken from late Quaternary deposit strata at different site in North China.

为了选择更合适于中国北方沉积物样品细颗粒OSL测年的实验程序和技术，进行了华北地区不同沉积环境的现代沉积物样品的细颗粒天然IRSL和GLSL信号测量，黄土细颗粒IRSL和GLSL的光晒退测试，不同方法获得的等效剂量值的比较分析，以及取自华北不同地区的40余个晚第四纪沉积物样品的IRSL和GLSL测年。
