According to the morphological characteristic variations,4 body measurements,i.e.withers height,body length,chest girth and fore shin circumference were measured on the spot,and 25 items in 11 types of appearance character were describedand their phenotype frequencies were computed,14 coat color were classified andtheir frequencies were computed.

根据形态学特征的变异特点，对17个山羊群体的四项体尺即体高、体长、胸围、管围进行了现场测定，对11个类型的25项外形特征指标进行了分类描述和表型频率估计，对14种毛色类别进行了表型分类和频率估计。

In different degree of saline and alkali conditions controlled in lab or under field, contents as followed were determined: the absorption, transportation and distribution of major cations Na~+, K~+, Ca~(2+and Mg~(2+) in indicator plant; organic solute, and antioxidase activities, including superoxide dismutase, catalase and peroxidase POD characteristics of individual, population and community of the plant. Responses of the indicator plant to environment from physiological to community aspects were systemically discussed in this document.(1 Vegetional characteristics and edaphic indicators including bare patch index, dry biomass, percent cover by perennial plants, growth indicators of Leymus chinensis, soil organic matter and pH were sensitive to saline-alkali grassland degeneration.

Comparative study on two levels of population and modules of mutualspecies in the two stations demonstrates that feature index tend to diminish suchas height,tussock amplitude,size,number,density and dry weight;and thegrowth analysis index incline to increase such as RGR、ULA、chlorophyllcontent and effectiveness of plant multi-leaves of the populations and DULA、DUMR、DAGA and DRGRa of the modules;and the dynamic curves of thepopulations and the modules also tend to steadily increase along with thetemperature ascending,heat accumulation and combination between water andheat in moderate-temperature steppe from fierce fluctuation alongside naturalprecipitation in warm-temperature steppe,illustrating that the transformabletendency from increasing the numbers of tussocks and tillers in order to expandthe resource range to seize in warm-temperature steppe to steadily improve drymatter production function of the populations and the modules in moderate-temperature steppe.

两个不同热量型研究站点共有种种群与构件两个水平的比较研究表明：随纬度增加和气温降低，种群与构件高度、丛幅、大小、数量、密度和干重等特征指标趋于降低和减少，而种群RGR、ULA、叶绿素含量和植物多叶性与构件DULA、DUMR、DRGR和DRGRa等生长指标则趋于增加，种群与构件的生长动态曲线也从随天然降水而剧烈波动趋向于随气温升高、热量积累和水热配置状况而稳定增长，说明各共有种从暖温型草原区增加植物种群与构件的大小和数量以扩充资源利用范围向中温型草原稳定地提高种群与构件的干物质生产性能的方面转变的趋势；同时，物质与能量的分配也从较多地投资于繁殖器官产生大量后代以适应未来降水的不可预期变化趋向于同化系统的构建和干物质生产效能的提高以抵御低温和干旱对物种生存的威胁，充分显示出不同温度条件及其水热组合对植物种群形态结构和生长繁育模式的显著影响及其响应特征。
