禁牧补助对环县天然草原生产力变化影响监测

Monitoring of the Effect of Grazing Prohibition Subsidies on Natural Grassland Productivity Changes in Huanxian County

通过对环县10个天然草原固定样地连续五年（2011-2015年）的监测,对其植被盖度、高度、植物种数和产草量进行分析,经过五年的修养生息,草原植被得到恢复,天然草原生产力得到提高,草原禁牧补助政策效果明显。

This study analyzed the vegetation coverage,height,number of plant species and grass weight through monitoring10 natural grassland fixed samples in Huanxian County during five consecutive years（2011-2015）.After five years of cultivation of interest-bearing,grassland vegetation is recovered,and natural grassland productivity is improved and therefore the grazing prohibition subsidies has significantly obvious effects.
