摘要
通过对达茂旗退化干草原草场和荒漠化草场进行草场松土和围封, 结果表明: 增加了土壤含水量, 提高了植被高度、盖度、密度和生物量, 种群优势度发生了明显变化。松土加围封效果要比单一松土或围封效果好, 因而, 起到了松土和围封的双重效果。
The results of soil loosing with enclosing experiments in the grassland and desert grassland of degeneration in Damao Banner Inner Mongolia show that soil loosing can improve physicochemical characters of the range soil and promote the growth of grasses and herbs.The Vegetation can be raised by the height,cover,density and yield.The dominant position of plant community takes place distinct changes.Soil loosing with enclosing can raised the yields of the ranger more and more obviously.
