There is 2.2k㎡ reed in the Populus Nature Reserve , accounting for the Populus Nature Reserve of 0.1% ,while only 0.8k㎡ in core zone, accounting for the core zone of 0.04%.The paper based on the Field investigations of Reed population in the Populus Nature Reserve of the middle reaches of the Tarim River, in this paper the relationship between the Reed population biomass and electrical conductivity and the relationship model between aboveground and belowground biomass are studied. It uses the methods of statistics and ecology, through field sampling , gaining the more accurate data about reed construction biomas,and then from laboratory analysis ,gaining the data of conductivity, organic carbon and nitrogen. On this basis, analyzing the relationship between the population of reed construction biomass and electrical conductivity, aboveground and belowground biomass model and biomass of underground space vertical distribution , Along with the Content of reed wetlands organic carbon and nitrogen, get the C/N, and analyzed the correlation among them, and gain the relationship model. The paper provides the basic data for the restoration of vegetation, ecological rebuilding, environmental building, the stability of Oasis and economic development of farmers and herdsmen.
