英文摘要	Climate change and agriculture are strongly related. The management of farmland can influence a variety of agro-ecological processes and affect greenhouse gas (GHG) emission. Based on reported data, this study conducted a meta-analysis to evaluate the role of conservation tillage (CT) in managing climate change in Northwest China. The results indicated that CT significantly improved the concentration of soil organic carbon (SOC), crop yields, and crop water use efficiency (WUE) compared with traditional tillage, and the practices with straw return were significantly higher than those without straw return. With an extended duration of the management, the SOC sequestration of each CT practice showed an increasing trend, but the crop yield did not show an obvious trend. After 5 similar to 16.16 t CO2-eq center dot ha(-1) and 8.22 similar to 21.53 t CO2-eq center dot ha(-1) compared to traditional tillage, respectively. In most CT practices, winter wheat-summer maize rotation (W-M) planting pattern had the best SOC sequestration, and spring wheat showed the highest increasing of yield and WUE. More specifically, compared to traditional tillage, the SOC concentration under W-M increased by 10.15 similar to 20.09%, and the yield and WUE under spring wheat increased by 6.87 similar to 17.83% and 8.82 similar to 46.32%, respectively. In conclusion, CT played a positive role in tackling climate change in Northwest China.
