对退化羊草草原浅耕翻处理后植物群落恢复演替动态的研究结果进行了报道．１１年的变化结果如下：处理群落种的丰富度增加．群落种多样性指数在１１年中的分布符合方程Ｄ＝２．４３－０．４９ｔ＋０．０４ｔ２，均匀性指数分布符合方程Ｅ＝１．４３－０．８５ｔ＋０．０２７ｔ２．群落密度和生物量均较处理前有显著的增加．羊草是造成群落密度和生物量变化的最主要种群，其重要值在１１年中分布符合方程Ｉ＝２０２．９－７８．４／ｔ－０．２２／ｔ２，表明在演替开始的前几年羊草恢复较快，随着时间的延长，增加变缓并保持在一定的水平．１１年的恢复过程可划分为羊草＋少年生杂类草、冰草群落（１—４年）；羊草群落（５—８年）和羊草＋冰草＋多年生杂类草群落（９—１１年）三个群落阶段．１１年的恢复处理群落并未恢复到原生羊草草原群落的水平、演替将继续进行
The results of the research on the recovery succession of plant community after the shallow tillage in the degraded Leymus chinensis steppe were reported. The results of 11 years of change are as follows: The abundance of species in the community was increased. The distribution of community diversity index in 11 years was in accordance with the equation D = 2.43-0.49t + 0.04t2. The distribution of evenness index accorded with the equation E = 1.43-0.85t + 0.027t2. Community density and biomass increased significantly compared with those before treatment. Leymus chinensis was the most important species that caused the community density and biomass change. The distribution of the important values in the 11 years was in accordance with the equation I = 202.9-78.4 / t-0.22 / t2, indicating that before the beginning of succession Leprosy a few years to recover faster, with the extension of time, increasing slowed and maintained at a certain level. The eleven-year recovery process can be divided into three groups: Leymus chinensis + juvenile miscellaneous grass, Agropyron community (1-4 years), Leymus chinensis community (5-8 years) and Leymus chinensis + Agropyron + perennial herbage community - 11 years) Three community stages. The 11-year restoration community did not return to the level of the native Leymus chinensis community, and succession will continue
