摘要
Abstract
Niche breadth and niche proportional similarity of 28 species in 5 dominant shrub populations in Liangucheng Natural Reserves of Minqin County were calculated and analyzed. The results showed that Bi>0.5 were five, 0. 1 < Bi <0.5 were thirteen, Bi≤0. 1 were thirtyeight. That indicated that community structure is simple, and annual short-life plants may get into the communities while the niches of the dominant species decreased. Niche similarity rations of the species in the Potaniniarrumgolica, Kalidium cuspidatum and Oxytropis aciphylla were relatively smaller. Niche similarity rations of the species in the Ephedra przewahkii and Reaumuria soongorica were higher. That indicated that the dominant species of shrub layer has a higher resource utilization degree of similarity. The study provides scientific basis for rational use and management of plant resources in natural reserves.关键词
