摘要:
采用β多样性指数测度了不同规格切割草皮样方的群落多样性及与原生群落的相似性，以衡量不同规格的回覆草块样方的群落恢复效果。揭示生境被分割的程度及不同样方的群落多样性。对实验区人工切割草皮群落的β多样性指数进行了研究，结果表明，βW（Whittaker指数）和βc（Cody指数）指数因取样面积的大小而变化，βW指数随取样面积的增加而增加，而βc指数随取样面积的增加而减少。β多样性指标以物种的个体数作为测度指标将导致较大的误差，而以相对盖度、重要值作为测度指标时得到的结果较合理。相似性指数（Jacard指数和Sorenson指数）测定结果表明，取样面积越大、与背景越相似的群落，恢复效果越好。
Abstract:
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.
