Study and Comparison of the carbon sequestration by Atriplex canescens and Hulthemia persica in Nowdahak Range Research Station, Qazvin province. E.E.R. . 2014; 4 (2) :40-52

Greenhouse gases (GHG) are a serious threat to humans and environment. Greenhouse gases have been different sources, but main factors are fossil fuels, industrial processes, deforestation and agriculture. What is now more than ever before should be considered according to the role of forests and rangelands in atmospheric carbon sequestration? Carbon sequestration is to changes in atmospheric carbon dioxide to form organic compounds with carbon by plants and capture for a certain period of time. Based on this research project in a completely randomized factorial experiment format was done. This study estimated and compared the amount of carbon sequestration by Atriplex canescens and Hulthemia persica, determine the economic value of carbon sequestration and determine the contribution of soil and plant carbon sequestration. In order to measure the organic carbon in soil and plants, respectively Walki Black and Combustion methods were used. The results showed that carbon sequestration by Atriplex canescens (41,626 ha) more than Hulthemia persica (32,461 ha) and bare area (26,654 ha) is. Therefore, the amount of organic carbon in areal biomass more than underground biomass and rate of soil organic carbon in first depth more than second depth. Share of soil in carbon sequestration in the planted region by Atriplex canescens, 87% and in an area with dominant cover of Hulthemia persica is 97%. So we can conclude that the soil in rangelands, most organic carbon reservoir is considered.
