不同改良措施对典型草原退化草地植物群落影响的研究

Study on the Effect of Improving Typical Degraded Grassland by Different Methods

论述了不同降水年份(1997年干旱、1998年降水正常)及不同改良措施对典型草原退化草地植物群落的影响,结果表明,各种退化草地改良技术对退化草地的植物群落均有明显的效果,改良草地的第一性生产力增加,植物群落结构发生变化,优良牧草增加,植物群落的盖度、高度增加明显。

The research group selected the typical degraded grassland in the semiarid steppe area of inner Mongolia of china,undertook the improvement methods such as fencing,losing soil,shallow ploughing,reseeding.After the 4 years,the results indicated that all these methods have showed remarkable effects in different extents,especially the fencing,losing soil,shallow plowing .These experimental results have provided the scientific foundation for improving degraded grassland.
