宁夏CO_2、CH_4、N_2O温室气体排放量估算及减排措施

Measurement on CO_2、CH_4、N_2O Emission and Emission Reduction Methods

宁夏2003年排放CO2、CH4、N2O总量1048.4047万吨,较1985年增加了1.91倍。1985年和2003年CO2排放量分别占总排放量97%、98.25%;CO2排放量中煤炭燃烧排放量分别占39.52%、61.17%。农田排放量分别占49.89%、25.69%,秸秆燃烧分别占10.59%、13.14%。大力发展洁净煤技术是主要减排措施,同时要充分利用当地风能、太阳能、生物质能再利用。科学施肥,大力植树造林,增强对CO2的吸收量。

Total emission of CO2, CH4, N2O was 10. 484,047 million tons in 2003, which was 1.91 times more than that in 1985. CO2 emissions were 97% of total gas emission in 1985 and 98.25% of total in 2003. CO2 emission from coal burning, agricultural, crop stalks burning were 39.52%, 49.89% , 10.59% in 1985 respectively, 61.17%, 25.69% and 13. 14% respectively in 2003. Development of coal cleaning technique was the main measure to reduce emission, as well as strengthen reuse of local wind energy, solar energy and development of energy crops. Management of scientific fertilization, afforestation will also effectively control CO2 emission.
