摘  要：
对昭苏马场未封育与封育春秋草场植被进行了调查分析,结果表明:未封育草地植物优势种是亚洲百里香和草原苔草,封育草地植物优势种是针茅和草原苔草;未封育草地植物种类为28种,群落盖度为62.8%,地下植物量1 452.7 g/m2;封育后草地植物种类为31种,群落盖度和地下植物量分别增加了41.0%和34.5%;禾本科草类的重要值由未封育的17.6%增加到封育后的35.2%,豆科和菊科草类基本保持稳定,封育后藜科和杂类草的重要值比未封育时减小了13.5%;封育草地的丰富度指数和多样性指数均大于未封育草地,而均匀度指数则相反。

摘  要：
An investigation on the effects of enclosing spring-autumn grassland vegetation in Zhaosu horse ranch was conducted.The results show that the dominant species in non-fencing area are Thymus asiaticus and Carex liparocarpos while Stipa capillata and Carex liparocarpos in fenced area.There are 28 plant species in the non-fenced area,their coverage is 62.75%,and under-ground biomass is 1 452.7 g/m2.The plant species,community coverage,and under-ground biomass increased 10%,41% and 34.5% respectively.The IV of Gramineae grass increased from 17.58% in non-fenced to 35.15% in fenced area while Kochia and weeds decreased 13.5%,and Leguminosae and Compositae were relatively stable.The richness index and diversity index are higher in fencing area than those in the non-fencing area,while the evenness index being reverse.
