摘要
水稻是中国农业生产中的一种重要作物 ,其对中国 GDP的直接贡献大约 2 0 0 0亿元 ,占全国农业总产值的 1 0 %。然而如同其它农业活动一样 ,水稻生产也带来了一些环境问题 ,其成本并未得到全面的评价 ,也未体现于政策制订中。研究选定湖南和湖北两个省 ,分别对水稻生产的环境成本作了估算和评价。经过估算 ,两个省 1 995年的环境成本为 2 5～ 1 1 0亿元 ,约为农业总产值的 1 %～ 4 .5 %,考虑到目前水稻生产的发展趋势以及国家环境政策变化 ,这些成本在 2 0 2 0年将可能达到
Rice is the most important crop in China's agricultural economy and will remain so for the foreseeable future Its direct contribution to China's GDP is about 200 billion yuan and provides some 10 % of national gross agricultural product However. rice production, like many other agricultural activities,brings a number of serious environmental problems with economic costs that have not been fully assessed and are not adequately considered in policy making Two major rice producing provinces, Hu′nan and Hubei, were selected to estimate the environmental cost in the present study For these two provinces it was estimated that the costs reached to 2 5 to 11 billion RMB in 1995, equal to 1 0% to 4 5 % of agricultural GDP, though with some uncertainly about the cost of upstream and downstream damage Given current rice production trends and environmental policies these costs could triple even more by 2020
