The comparative study on vegetation background survey of the stationsand the comparison on level of phytocoenology on zonal habitats indicates thatthe diminishment of the numbers of families,genus and species,compositionof life types,diversity of communities and habitats,;and the increscence in theproportion of photosynthesis functional groups of C3/C4 plant,richness ofspecies,density of tussock and tiller,diversity of species,evenness,leaf areaindex,leaf area duration,dry matter production of communities alongside thelatitude increasing and the temperature decreasing;and the dynamic curve ofthe community productivity also tend to steadily increase along with thetemperature going up and the heat accumulation gradually in moderate-temperate steppe station from violent fluctuation along with seasonal badly-distribution of precipitation in warm-temperature steppe station;manifestingthat transformable tendency of productivity pattern of the community from morevigorous net assimilation,sparser and higher crops stricture of tussock and tiller,and possession on more resources by less species inclined to thicker in densityof crops,superior effectiveness of multi-leaves and pattern of multi-speciesresource sharing,reflecting that bigger disparity of the vegetationcharacteristics and the style of the community growth in the two differentthermal-type steppe stations owing to background of natural-historicenvironment and combination of water and heat.

内蒙古草原区两个不同热量型研究站点植被本底调查和显域地境群落学水平的比较研究表明：随纬度增加和气温降低，植物科、属、种的数目，生活型组成，群落类型和生境类型的多样性均趋于减少，而C3/C4光合功能群比值和群落的物种丰富度，株丛密度，物种多样性，群落均匀度，叶面积指数，叶面积持续时间和群落干物质生产能力均趋于增加，群落生产力动态曲线从随天然降水的季节分布不均而剧烈波动趋向于随气温逐渐升高和热量逐步积累而稳定增长，显示出两站点植物群落从较为旺盛的群体净同化作用、较为稀疏高大的群体结构和少数物种占有较多群落资源的生产力格局向较高的群体密度、优良的多叶性能和多物种资源共享的群落生产力格局转变，反映出在内蒙古草原区不同的自然历史环境背景和不同的温度条件及其水热组合状况影响下，两个不同热量型草原站点植被性质的分异特征和显域地境群落生长模式的较大差别。

In order to resolve the problems of the enterprise information integration platform, such as the lacks of reconfiguration and transplantability that cant adapt to the development and change of business, the deficiencies in integrating the heterogeneous information resources, this paper expands the management ideology of ERP, which is based on the thorough research on the enterprise management theory, and combined with the analysis on the process of enterprise manufacture and business. Proposes the advanced enterprise management schema which is on the basis of the integration and conformity between BPR and ERP, adopts the method of Dynamic Enterprise Model, and supports the BPCI(Business Process Continuous Improvement).
