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.
