In order to study vegetation niche characteristics in artificial fencing field of semi-arid area, three measures were applied in Liuyangbao fencing field in Yanchi County, namely core zone(E), marginal zone(E1), peripheral zone(E2); 1 m×1 m quadrat was randomly set up in lines for respectively investigating the names of plants, species, numbers, height, coverage, biomass etc. The niche breadth and niche overlapping of plants in artificial fencing field in Yanching County were measured by means of Levins niche breadth index and Pianka niche overlapping index. The results showed that Artemisia scoparia, Artemisia ordosica, Salsola ruthenica are main dominant species in artificial fencing field; the larger niche breadths in core zone were Artemisia morrisonensis and Salsola tragus with 0.76, 0.71. The larger niche breadths in marginal zone were Artemisia ordosica and Salsola tragus with 0.72, 0.69 and the larger niche breadths in peripheral zone were Salsola tragus and Artemisia ordosica with 0.73, 0.64. The results of niche overlapping analysis also showed the largest niche overlapping of all zones appeared to the niche with small breadth of plants. In addition, the niche overlapping and niche breadth did not have a positive correlation.
