alpine frost desert soil-
The north slope on the east part of qilian mountains was separated into 6 vertical distribution zones : alpine cold desert meadow 、 alpine meadow 、 alpine bush meadow 、 mountain forest grassland 、 mountain grassland 、 and mountain desert grassland, there are also some areas of alternative distribution
祁連山東部北坡根據氣候、土壤、地貌等因素,分為6個垂直分佈帶:高山寒漠草甸帶、高山草甸帶、高山灌叢草甸帶、山地森林草原帶、山地草原帶和山地荒漠草原帶,有交替分佈的地段。2. because of feeble development, sandy desertificational land in high frigid regions of china have higher sands content, which is commonly larger than 750g / kg, there are also higher sio2 correspondingly, which is commonly larger than 600g / kg
2 、高寒地區沙質荒漠化土地,由於土壤發育微弱,土壤砂粒含量較高,一般含量均大於750g kg ,相應的sio _ 2含量也較高,含量均在600g kg以上。Took sha - zhuyu and east shore of qing - hai lake as the examples and based on the mass of field survey and soil analyse, took comparative method, we carried through the researches on the causes of the desertification, the origin of sandy desertificational land substance, the development diversification and difference of soil characteristic in process of manual and spontaneous vegetation recovery in high frigid regions and make out the taxonomy of desertificational land in high frigid region of china. the result obtained are summarized as follows : 1. the development of the desertificational land in high frigid regions is caused by the manual and spontaneous factors
論文首次對高寒地區的砂質荒漠化土壤進行系統研究,以沙珠玉和青海湖東岸為例,通過野外考察和土壤樣品室內化驗,採用對比分析的研究方法,對中國高寒地區荒漠化的成因和研究區砂質荒漠化土地的形成演變,土壤發生特性、人工植被恢復和自然植被恢復過程中土壤的發育差異和性質變化進行系統研究,並用系統分類體系對研究區土壤進行類型劃分,得到主要結論如下: 1 、高寒地區荒漠化的發生發展是在自然因素和人為因素共同作用下進行的,沙珠玉地區風沙土是就地產生的,青海湖東岸地區風沙土主要是由風從湖的西岸搬運而來的,兩地區砂質荒漠化發展仍然十分嚴重。The climax development group is isohumosols after sandy soil fixed under vegetation recovery condition in research regions. there was no different in soil type after 40 years developed. this manifested that soil formation and development process is very slow in high frigid regions
6 、研究區土壤在植被恢復條件下,風沙土被固定以後,經過40多年的發育,類型未發生明顯分化,表明在高寒地區土壤的形成發育過程相當緩慢,土地一旦發生荒漠化,恢復治理相當困難,所以荒漠化防治要以預防為主。分享友人
