    本文主要從兩方面對草原三化進行了分析，首先從表面上看有以下幾方面原因，人口多、牲畜數量多、草原利用不合理、新技術推廣差、草原自然災害頻繁、人工半人工草地少產量低。其次又挖掘了草原退化的深層原因，第一對草原資源的功能和作用的認識具有片面性，只重視草原的經濟效益，卻忽略了它的生態效益；只重視草原資源的再生性，卻忽略了它的適宜可利用性。

  4. Meanwhile, most aspects about this perspective are concerned, which include quantification of the soil water background of the plateau area, the regional spatial variation of soil water background and variation along the slope, mosaic structure and seasonal changes etc. the results show that : ( 1 ) for the fundamental circumstance for vegetation development is the original debilitated slope, so the perspective of soil water background specially for the loess plateau refers to the soil water conditions on the original slope. ( 2 ) the value of soil water background appears to be a descending trend from south to north based on the difference of vegetation zones. in the forest zone, soil moisture contents beneath 3m depth from the soil surface are more than 12 % usually ; in the forest - pasture zone, the values of soil moisture content beneath 4m depth underground are more than 6 % and stable, and tend to be ascending while the depth increases ; but the values in the dry pasture zone is lingering between 4 % to 6 % from the surface layer to sub - layers
