| 摘 要： | 对不同退化阶段伊犁绢蒿Seriphidium transillense荒漠草地的主要经济性状特征进行了调查与分析.结果表明,草地由未退化阶段演替至重度退化和极度退化阶段,草地的植物种类组成、群落高度、盖度、生产力、营养价值均发生了一系列变化;植物种类减少,高度、盖度、生产力下降,饲用价值处于一个劣变过程,表现出牧草的家畜适口性较差,利用率低,由良等牧场演变为中低等牧场.

| Abstract: | Main economic character of the desert grassland of Seriphidium transillense is investigated and analyzed under different degenerate stages, result shows that the Seriphidium transillense desert grassland evolves from undegenerate stage to serious degenerate stage, extremely degenerate stage;a series of changes in composition of plant species, community height, coverage, yield of grassland has taken place; plant species decreased, the plant height, coverage, yield declined, value of feeding is descended~ showing worse forage rat- ing, lower utilization and the evolvement from good pasture to middle-low pasture. |

| Keywords: | degenerate stage economic character of grassland change |
