摘　　要：以泰州地区典型种植方式的稻麦轮作系统农田为研究对象,比较施用不同水平生物质炭对生态效应(农田土壤温室气体排放、理化性质和养分状况)和经济收益(经济收入纯收益和生态经济净收益)的综合影响。结果表明:相比于单施氮肥,配施生物质炭能够显著降低农田CH4、N2O全年排放总量和全球变暖潜能值(GWP),同时对农田土壤的理化性质和养分状况具有良好的改善作用;在经济收益方面,配施2 t/hm^(2)生物质炭能够取得最佳的经济收入纯收益和生态经济净收益。Taking the field of the rice-wheat rotation(typical planting patterns in Taizhou)system as the research object,this paper compared the comprehensive effects of biochar with different levels on ecological effects(greenhouse gas emissions,physical and chemical properties and nutrient status of farmland soil)and economic benefits(net economic income and net ecological economic income).The results showed that compared with nitrogen fertilizer alone,the combined application of biochar could significantly reduce the total annual emissions of CH4and N2O from farmland and GWP.At the same time,it could improve the physical and chemical properties and nutrient status of farmland soil.In terms of economic benefits,the optimal net economic income and net ecological economic income could be obtained by applying 2 t/hm^(2)biochar.
