The dynamic changes in community height, coverage, abundance, above ground biomass and plant diversity in Stipa bungeana typical steppe was investigated by a quadrat method. There were six treatments: Unexclosure, 5-year old exclosure (5 a), 10-year old exclosure (10 a), 15-year old exclosure (15 a), 20-year old exclosure (20 a), and 25-year old exclosure (25 a) plots.

采用样方法对云雾山干草原区本氏针茅草地群落进行长期定位监测，对未封育样地和封育5，10，15，20和25年样地群落的平均高度、盖度、多度和地上生物量以及植物多样性进行实地调查分析，以研究围栏封育对草地植物群落特征动态变化的影响。

The indication of MD and HD, according to the fuzzy comprehensive evaluation of vegetation and soil, at Leymus chinensis +forb community, were 0.7426 and 0.5611, respectively, and at Stipa baicalensis + Leymus chinensis community, were 0.7702 and 0.59804, respectively.

根据植被与土壤相结合为指标体系的模糊综合评价得出的指示度分别为；羊草+杂类草群落中度退化区为0.7426、重度退化区为0.5611；贝加尔针茅+羊草群落中度退化区为0.7702、重度退化区为0.5980。

The key species in the pioneer species period is Achillea capillaries, Izeris denticulate, Salsola colliha., than the key species gradually change to Potentilla spp, Heteropappus altaicus, Cleistogenes spp in the species gradually prosperity period, Lespedeza dahurica, Stipa bungeana, Artemisia sacrorum in the species quasi-steady period, Lespedeza dahurica, Artemisia sacrorum in the species relatively steady period, Peri ploca sepium Bunge, Clematis fruticosa turcz, Spiraea spp in the bush pioneer species invasion period.

其中先锋植物物种期以茵陈蒿、苦买菜、猪毛菜为关键种；物种渐繁荣期以委陵菜、阿尔泰狗哇花和隐子草为关键种；物种鼎盛期多物种共存，关键种不明显；物种准稳定期以长芒草、铁杆蒿和达乌里胡枝子为关键种；物种相对稳定期以铁杆蒿、达乌里胡枝子为关键种；灌木先锋物种主要有杠柳、木本铁线莲、绣线菊等。

The tolerant species include Stipa grandis and Agropyron michnoi, which did not change in distribution under mowing disturbance.

对内蒙古羊草草原主要植物种群能量现存量对刈割频次响应的研究表明，在17年不同频次刈割干扰影响下，植物种群能量现存量随刈割频次的变化表现出不同的变化趋势，据此可以划分出3个不同的刈割响应类群：受抑种、耐刈种和受益种。

If Altingia, Dipterocarpaceae of Jie Xiang, such as Brokaw, such as Fagaceae, Lauraceae tea branches and a number of evergreen species, Quercus humilis small, Stipa purpurea, Artemisia Tibet.

如阿丁枫、龙脑香科的羯布罗香等，如壳斗科、茶科和樟科的一些常绿树种，高山栎小蒿草、紫花针茅草、西藏蒿。

The experimental results are as follows:1、 In the Inner Mongol typical steppe community, Stipa grandis、 Koeleria cristata 、 Artemisia frigida and Kochia prostrate turn green relatively early.

初步得出以下结论： 1、在内蒙古典型草原群落中，大针茅、洽草、冷蒿和木地肤返青较早，糙隐子草返青最晚，黄囊苔草和星毛委陵菜的生长开始得最早。

In this paper, we studied seasonal variation of endogenous IAA、 GA_3、ZR and ABA content of Leymus chinensis、 Agropyron michno、 Stipa grandis、 Cleistogenes sguarrosa、 Koeleria cristata、 Carex korshinskyi、 Allium bidentatum、 Artemisia frigida, Kochia prostrate and Potentilla acaulis in different restoring succession stages, which were determined by ELISA in the growing season in 2005. At the same time we recorded the phenological development and growing regulation of each kind of plant.

本文于2005年生长季，对处于不同恢复演替阶段的羊草、米氏冰草、大针茅、糙隐子草、草、黄囊苔草、双齿葱、冷蒿、木地肤和星毛委陵菜十种植物，运用酶联免疫吸附法，测定内源生长素、赤霉素(GA_3)、细胞分裂素和脱落酸含量的季节动态，同时记录每种植物的物候期和生长规律情况。

Grazing reduced aboveground biomass of the communities except in the Stipa klemenzii community. In this case annual warm season plant, Salsola collina, became absolutely dominant species in the community under heavy grazing intensity.

群落地上现存量一般随放牧强度的增大而下降，但小针茅群落反之，主要与一年生植物猪毛菜的生物量迅速增加有关。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
