摘要
农业固碳研究多针对农田土壤固碳,且农业固碳受气候、生物、土壤等因素影响较大,环境因子不可控,导致农业固碳效率低。目前,农业固碳鲜少针对设施农业固碳,而随着现代设施农业发展规模日益增大、环境调控设施设备趋于自动化智能化,资源利用效率、单位面积土壤产出率及生产效率都大大提高,设施农业打破了时间和空间的界限,在一定程度上提高了作物产量及其固碳效益。为此,通过分析设施农业发展现状,结合农业固碳研究的现状及存在问题,在设施农业发展的基础上分析了设施农业在固碳方面具有生产周期长、环境因子可控、半封闭式生产及可利用资源广且资源效率利用率高的优势,并探讨了设施农业固碳研究的重要性,结合环境发展需求及碳贸易,提出了发展设施农业固碳思路和前景。
Almost all studies on agricultural carbon sequestration are concentrated in farmland soil carbon sequestration. Agricultural carbon sequestration is greatly influenced by climate, biology, soil and so on.Uncontrollable environmental factors lead to the low efficiency in agricultural carbon sequestration. At present,fewer agricultural carbon sequestration aims at facility agriculture. With modern facility agriculture＇s development scale increasing day by day, the environmental regulate and control facilities and equipments being automatic and intelligentized,resource utilization efficiency,yield per unit area,and the production efficiency greatly improved.And to certain extent,it also helps upgrading the crop yield and efficiency of carbon sequestration. Therefore,this paper analyzed the present situation of facility agriculture development combined with the present status of agricultural carbon sequestration research,and existing problems. The paper also analyzed the advantages possessed by facility agriculture in carbon sequestration： Long production cycle, controllable environmental factors, semi closed production,rich usable resources,and high use ratio of resources. Besides,the paper explored the importance of studying on facility agriculture carbon sequestration,and put forward the thoughts and prospect for developing facility agriculture carbon sequestration on the basis of combining environmental needs and carbon trade.
