[Function of artificial grassland in restoration of degraded natural grassland and its research advance].

This paper analyzed the degradation actuality of natural grassland, its reasons and corresponding restoration ways. Natural restoration is the easiest way, but it is very slow. The establishment of some artificial grassland is the most effective way to lessen the oppressiveness of natural grassland. The research advances on artificial grassland were summarized, and the ways for promoting the sustainable development of pasturing area were suggested.
