%X The accumulation quantity of overground part is less than its underground part in the Carex lasiocarpa wetland, In the component of the overground part,the accumulation quantity of leaf component is bigger than its sheath component, and the accumulation of the spike component is the least. In the component of the underground part,the accumulation quantity of redicula component is bigger than its rhizoma componen; The nutrient element storage of soil dispart is predominant among the different disparts. The order of storage quantity of the nutrient elements in the soil of Carex lasiocarpa wetland is as following: K>Fe>N>Ca>P>Mg>Mn>Zn>Cu.The order of the absorbance index of the wetland is Mn>N>P>Zn>Mg>Cu>Ca>Fe>K. The order of the utilization factor of this wetland is: Mn>N>P>Zn>Mg>Cu>Ca>Fe>K; The order of the cycle index of Carex lasiocarpa wetland is Ca>K>Mg>N>P>Mn>Zn>Cu>Fe.The remaining proportion of Ca, K in the ecosystem is the least, and its fluidity is bigger, The remain proportion of Fe in the ecosystem is bigger than other elements and its fluidity is small.
