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。Obtaining full and accurate information on the spot, basing on the fractal theory, fully using remote sensing image as the main research data and relative thematic map as reference data, aiding of pci which is a powerful image processing software of remote sensing technique, the land desertification and the change of transitional belt between oasis and desert in yutian county are analyzed quantificationally. the rational proposals are tabled for the desert controlling and area rebuilding in the future, furthermore, this paper deeply discusses and validates the effect of fractal approach applied in the desertification research
