Grassland ecosystem restoration and reconstruction in the site of highway construction in the Zoige wetland combining with the rapid recovery mode of artificial turf cutting technology and relocating technology are of the good practical significance in germplasm resources protection area of grassland ecosystem conservation and improvement of germplasm resources. β diversity index is used to measure community, the purpose is to to measure the results of the different grass plots restoration, the meaning lies in revealing the extent of habitat is divided. Through the sampling investigation of ecological restoration of sward meadow community of Langchuan national highway in the Zoige wetland, the diversity of incised sward with the β diversity index was evaluated. It is showed that both βW(Whittaker index)and βc(Cody index) were influenced by the change of sampling area, the βW index increased when the area enlarged, the βc index was opposite. When β diversity index was measured with species numbers, some errors would arise; when it was measured with relative cover and important value, there was no obviously difference. Similarity indices (Jacard index and Sorenson index) show that the recovery effect was better if the sampling area was larger, and the background was similar to the community.
