摘要
通过调查江苏省全球环境基金项目区农户和专家的投入产出,使用成本效益分析方法和IPCC推荐的温室气体估算方法评估比较了3种种植方式(人工插秧、机械插秧和直播)的水稻在麦稻轮作复种"两晚"模式(水稻晚收,小麦晚播)下的社会、经济和生态效益。结果表明:水稻直播和机械插秧可以节省更多劳动力;农业机械燃油、施用化肥、稻田淹水等农作措施导致了大量人为温室气体排放;水稻种植方式为人工插秧的麦稻轮作模式能取得最优的经济和生态效益;"两晚"模式实施的关键是适时地利用近年来增加的农业气候资源。水稻人工插秧与麦稻"两晚"相配合的种植模式是减缓和适应气候变化的较优选择。
Based on the input-output survey of farmers and experts in one of the Jiangsu GEF project areas, the cost- benefit analysis method and greenhouse gases estimation method recommended by IPCC were applied to evaluate and compare the social, economic and ecological benefits of the artificial transplanting (ATR), mechanical transplanting (MTR) and direct seeding (DSR) rice under wheat-rice Double Late mode (late rice harvest and late wheat sowing). Results show that the MTR and DSR rice achieved obvious social benefits. Farming measures resulted in lots of man-made greenhouse gases emissions. The ATR rice and wheat rotation mode could obtain the best economic and ecological benefits. The Double Late mode has a good application prospect, but the key of implementing is timely exploiting the recently increased available agricultural climate resources. The cropping pattern of combining the wheat-rice Double Late mode with the ATR is a better choice to mitigate and adapt to climate change.
