    摘要:

    中国温室种植面积占世界的85%。基于物质平衡方法,选择中国主要温室农业区——华北区和长江中下游区,估算了温室农业的生态系统服务及其经济价值。结果显示,华北区和长江中下游区温室农业蔬菜年均产量分别比露天菜田高7405和30.95 t /hm2,CO2固定量高2.16 和0.74t/hm2,保持土壤量高13.86和11.41 t/hm2,保护土壤养分量高0.98 和0.06 t/hm2。以2004年价格折算,华北区和长江中下游区温室农业提供的生态系统服务价值分别为68871和34064元/hm2,比当地露天菜田高33946和5558元/hm2;环境成本分别为10.41和27.08元/hm2,比当地露天菜田高7.64和14.30元/hm2。从成本收益角度分析,无论是对农户还是全社会,温室农业带来的净效益都高于露天菜田,应该进行推广。

    Abstract:

    Greenhouse cultivation area in China accounts for 85% of global total area. Based on the mass balance approach, we estimated ecosystem services of greenhouse agriculture for two cultivation regions of China (Northern China and the Middle and Lower Reaches of Yangtze River). Results show that, compared to open vegetable field, greenhouse agriculture demonstrates higher capacity in yield (30.95 to 74.05 t/hm2), CO2 sequestration (0.74 to 2.16 t/hm2), soil retention (11.41 to 13.86 t/hm2), and soil nutrients protection (0.06 to 0.98 t/hm2). Based on 2004 prices, total economic values of ecosystem services of greenhouse agriculture in the two regions were 68871 and 34064 yuan/hm2, which were 33946 and 5558 yuan/hm2 higher than that of open vegetable field, respectively. Although the environmental costs associated with greenhouse agriculture in the two regions were 7.64 and 14.30 yuan/hm2 higher than that of open field vegetable field, it is worthwhile to promote greenhouse agriculture by producing higher net benefits for proprietary farmers and even the whole society.
