As the economic,political and cultu ral center of a nation or a region,cit ies are the carriers of human activi-ties.In a sense,only cities take the path of the coordinated sustainable development,it is possible for a cou ntry or a re-gion,even the whole world ,to develo p coordinately and sustainbly.Today,how to describe the urban sustainable develop-ing level and measure the coordinate d degree of environment,economy and society,has attracted more and more atten-tions of urban managers and research ers.City is assumed to be a big system composed by 3subsystems of environm ent,economy and society,a set of indicators for urban coordinated sustainab le development of Taiyuan have been d esigned accord-ing to the thought of coordinated sustainable development and the reality of Taiyuan development.In this ind icator set there are three levels,which can be c alled as target level,indicator lev el and statistic indicator level.Am ong them,tar-get level includes three high-generalized grade-1indicators,represe nting the development standard of economy,society and environment subsystems.In this paper,according to the ideas of system theory and QIAN Xue-sen's theory o f meta-synthesis methodology fromqualitative analysis to quantitative analysis,the level,the sustainabl e degree and the coordi-nated degree of urban development we re set up,which described the urban c oordinated sustainable developmen t scientifical-ly and quantitatively.The above indicator system and the method of quant itative description were applied to Taiyuan.Through calculating,we have got the economic developing level,social developing level,environmental quality situation and the overall developing level,of Taiyuan from1986to 1995.Also,we wo rked out the sustainability of the whole develop-ment,the respective coordinatabilities of the subsystems of economy an d society,society and environment,and environ-ment and economy,and the coordinata bility of the overall development of Taiyuan in the same period of time.The coordinat-ed sustainable development situati on was quantitatively described,an d the low development level was compr ehensively analyzed ,and suggestions were rais ed for its future coordinated sustainable development.

在牧草生长季节历年每旬降水量的基础上分别增加25%(试验当年降水量+比历年同期增加25%的水量)、50%、60%、70%、75%、0%6个量级,通过与历年观测数据对比研究水分对草地上生物量影响,揭示不同水分增加条件下牧草发育期和生物量的变化情... 在牧草生长季节历年每旬降水量的基础上分别增加25%(试验当年降水量+比历年同期增加25%的水量)、50%、60%、70%、75%、0%6个量级,通过与历年观测数据对比研究水分对草地上生物量影响,揭示不同水分增加条件下牧草发育期和生物量的变化情况,以及高寒草原牧草的发育状况、生物量与水分的关系。结果表明:对于不同种类的牧草,各阶段不同灌水处理间,主要优势种牧草对总产量的贡献率,6至7月变化不大,期间冷地早熟禾、矮生嵩草、扁蓿豆贡献率较大,但8月份对牧草总产量的贡献率变为西北针茅等禾本科牧草;随着水分的增加生物量随之发生了变化,扁蓿豆明显增加;且各牧草发育期也发生了变化。 展开更多
