Abstract: 【Objective】From the perspective of ecological balance, this paper mainly studied the influences and mechanism of carbon source and sink and its ecological effect under the 'Grain for Green Project ' and the key base construction of energy and chemical industry in Yulin so as to provide a scientific basis for reduction of carbon emission and increase of carbon sink.【Method】The estimation and analysis in this paper are based on carbon emission model, CASA model, carbon sequestration and oxygen release model as well as energy consumption statistics, MODIS-NDVI, meteorological data, etc.. 【Result】 Carbon emission of fossil energy consumption increased significantly in Yulin, with a cumulative emission of 8 576.66 104t from 2005 to 2009. Raw coal consumption was the main carbon source. The total carbon emission in Shenmu, Fugu and Yuyang counties accounted for more than 95% of the whole area. The mean value of NPP (net primary productivity, NPP) increased slightly at the average speed of 6 gC•m-2 each year from 2005 to 2009. NPP of Jiaxian, Mizhi and Zizhou counties grew significantly. The mean value of NPP showed a pattern of higher in the south and east, while lower in north and west and the regions which had lower value of NPP centered around Yuyang from northeast to southwest. The amount of CO2 fixed by vegetation was 11 429.3×104 t in Yulin from 2005 to 2009. Overall, the amount of carbon fixation was greater than that of carbon emission in Yulin from 2005 to 2009 and the differences would increase year by year, showing an increasing tendency of ecological surplus levels. Meanwhile, the balance between carbon source and sink and its ecological surplus displayed significant space differences. Shenmu, Fugu and Yuyang counties were the major areas of reducing carbon emission and increasing carbon sink and its ecological surplus level fluctuated significantly and ecological state declined year by year. 【Conclusion】The “Grain for Green Project” would help to increase carbon fixation significantly by vegetation. Increasing the proportion of forest serves as an effective way to increase regional carbon sink, improve regional ecological balance and ease the ecological stress.
