中文摘要	为了达到治理荒漠化的目的,实现生态环境的良性循环,在天然植被恢复和造林植被恢复治理荒漠化的过程中进行生物活性剂和固沙剂的试验研究。研究结果表明:生物活性剂Frisol A、Frisol F最适使用量分别为100 g/m~2、120 g/m~2。单独使用生物活性剂或同固沙剂Frisol S混合使用,对荒漠天然植被恢复都有明显的促进作用,样方内株数、植被盖度、生物量、当年高度分别较对照有显著的差异。运用生物活性剂,使柽柳造林成活率平均达到89.9%,沙枣造林成活率平均达到94.9%,分别比对照平均提高了14.1%和10.4%;柽柳的当年平均生长量、单株生根量都是未使用活性剂的2倍以上;沙枣的当年平均生长量、单株生根量都较对照提高了45.6%和86.3%。当固沙剂Frisol S>50 g/m2时,荒漠表面形成较厚的结皮,抗风蚀能力增强。
英文摘要	In order to achieve the purpose of desertification control, to realize virtuous circle of ecological environment, the experimental researches of bioactive agents and sand-fixation agent in the natural vegetation restoration and planting vegetation restoration control desertification process were conducted. The results show that the optimum quantity of the bioactive agents Frisol A and Frisol F respectively were 100 g/m~2 and 120 g/m~2; the two bioactive agents were alone used or uses with sand-fixation agent had significant role in promoting natural vegetation restoration, for example, there were obvious differences in plant number of sample plot, vegetation coverage, biomass and height in current year, compared with the control group; by adopting the bioactive agents, the average survival rate of Tamarix chinensis afforestation reached 89.9 percent, the Oleaster average survival rate reached 94.9 percent, which were respectively 46.7 percent and 23.0 percent higher than the control; the average growth, root quantity per plant of T. chinensis were more than two times with no used bioactive agents; the average growth, root quantity per plant of Oleaster were respectively 45.6 percent and 86.3 percent higher than the control; when the sand-fixation agent Frisol S content was gre ater than 50 g/m2, a thicker crust formed in the desertification surface, the anti-wind erosion ability was enhanced.
