2005年,对伊犁绢蒿Seriphidium transillense草地设置围栏内外草地植被和土壤对比,分析封育对草地植被和土壤的影响.调查结果显示:封育后,伊犁绢蒿个体植株高度增高,地上生物量上升,丛幅增大.封育后土壤条件得到改善,处于围封中的土壤容重较放牧利用中的土壤容重小,水分含量升高,尤其是 5~10 cm土层变化显著.围封3年内,草地植物组成成分无明显变化,但优良牧草产量比例增加.总体表明:围栏封育改善了草地植被生长状态,提高了草地质量.
Influence of fencing on Seriphidium transillense pasture in Yili region of Xinjiang
This paper compared plants vegetation and soil inside and outside of the fencing in Seriphidium transillense pasture in 2005, and analyzed the effects of fencing on plant vegetation and soil. The result showed that plant height, aboveground biomass and cluster of Seriphidium transillense had an obvious increase after enclosure. The soil quality was improved, the soil bulk density inside fence was less than that of the outside, but soil water content increased, especially in 5~10 cm soil layer. The plant components of the pasture had no obvious change, but the proportion of dainty grasses increased remarkable. In conclusion, enclosure improved plant growth and the quality of pasture.
