GHG Fluxes (CO2, CH4) of the first three years after flooding of the Eastmain-1 reservoir (Quebec, Canada)
Growing concern regarding the long-term contribution offreshwater reservoirs to atmospheric greetihouse gases (GHG) led Hydro-Qudbec, the largest electric power company in Canada, to study net GHG emissions from Eastmain-1 reservoir, which are the emissions related to the creation of a reservoir minus those that would have been emitted or absorbed by the natural systems over a 100-year period. Follow up ofthe CO2 and CH4 fluxes showed a rapid increase in both COz and CH,t emissions the first year after flooding and a rapid return to natural aquatic ecosystems values within 2 and 3 year for CH# and CO2, respectively. Overall GHG emissions from Eastmain-1 reservoir are veiy low in comparison to thermal power plant.
Based on the grey associative theory,an eco-province construction level assessment model is establisded.As a case,the eco-province construction level assessment index syetem in Anhui province is formulated,and the assessment reference sequence and compare sequence are established.The established model is utilized to evaluate the eco-province construction level in Anhui province.The result shows that,this model is scientific and effective for eco-province construction level comprehensive assessment which has great significance in pratice.
