| The biomass, rate of water content, carbon contend rate of aboveground modules of four shrubs in Mu Us sandy land were
measured respectively by harvesting, oven drying, potassium dichromate-sulfuric acid oxidation. There were four results as follows: （1）The water content rate among aboveground modules of four shrubs had significant differences and were in line with the general law of plants water. （2）The carbon content rate of main breaches were low, randomness carbon content distribution among modules were controlled by eco-physiological characteristics of plant. （3）The biomass density and carbon density of four shrubs were more than herbaceous species,rate of carbon content than trees like poplar and willow. （4）The main breach of four shrubs all had more rate of biomass and carbon than other modules, so that it was the main module that stores carbon and constitutes population. Characteristics of biomass and carbon distribution of four shrubs reflected that plants in arid and semi arid regions distribute biomass reasonably to get the maximum resources
and space for population living. For this, the shrubs with high carbon content rate such as Sabina vulgaris should be the main trees for carbon sink forests construction. |
