摘    要:通过对南京郊区5种夏季大棚设施蔬菜生态系统的物质和管理投入进行现场问卷调查,分析估算了不同设施蔬菜各个生产环节投入的碳成本以及碳排放强度等。结果表明,不同设施蔬菜单季单位面积碳成本介于(867.1±240.6)-(2039.4±1163.3)kgCE·hm^-2,物质投入碳成本在整个生产投入中占极其重要的份额,其中肥料投入的碳排放最大,占总碳成本的57.96%~82.37%,而农膜投入占11.97%~29.25%;不同设施蔬菜单位面积碳排放、单位产量碳排放及单位产值碳排放存在差异显著。综上,减少生产过程碳排放尤其是物质投入碳排放、提高施肥效益增加蔬菜产量、因地制宜选择蔬菜种植品种是促进蔬菜生产温室气体减排的重要途径。

关 键 词:设施蔬菜  碳足迹  温室气体减排

Abstract:A questionnaire survey of material and management inputs in production of five typical kinds of greenhouse vegetables from Nanjing was conducted. Carbon cost and C emission intensity involved in these vegetable production were evaluated using life cycle analysis methodology. Resqhs showed that the total C inputs in a single growing season of the studied 5 types of greenhouse vegetables ranged from (867.1 ±240.6 )kgCE. hm^-2 to( 2 039.4±1 163.3 )kgCE. hm^-2. While the material input possessed a poredominant proportion in the total C cost, fertilizers and agricultural films were found in a proportion of 58%-82% and of 12%-29%, respectively. Furthermore, there were significant differences in the C intensity either per hectare or per ton of production between the vegetable types. Above all, reducing C input in the growing of vegetables and better application techniques to improve nutrient uptake and choosing suitable greenhouse vegetable varieties would be an effective measure to increasing carbon sequestration and mitigation in soil.
