摘　　要：通过对荒漠草原区不同生产管理模式下家庭牧场草地植物特征的测定,分析探讨生产管理策略转变对牧场植被特征的影响。结果表明:荒漠草原家庭牧场草地生产力随降水量的变化而变化,生产管理策略转变后,在短期内对草地生产力影响较小,但长期实施有助于植物群落中建群种和优势种的恢复,主要表现为植物高度、密度、盖度和多年生丛生禾草种类增加,一二年生植物和多年生杂类草显著减少,根茎禾草的重要值显著提高。Based on the observation of vegetation characteristics of household ranches with different production management strategies in the desert steppe, the effects of production management strategies on vegetation characteristics in household ranch level were analyzed. The results showed that the pasture productivity of different household ranch changed with the precipitation, and the management strategy change had less effect on pasture productivity in the short term. While it would help to the recovery of the constructive species and dominant species, height, coverage and density in demonstration farm were higher than traditional farm; and the species of perennial bunchgrasses increased, annuals and biennials and perennial forbs decreased, and the importance value of the perennial rhizomatous grasses was significantly improved after the new strategies were adopted.
