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在线免费观看搞黄网站、ULA、chlorophyllcontent and effectiveness of plant multi-leaves of the populations and DULA欧美日韩国产VA在线、DUMRAV免费羞羞漫画在线观看真人、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.
