发展水田不仅可增加粮食生产,而且与自然环境密切相关,可改善生态环境。水田具有良好的贮水机能,其贮水能力仅次于森林,可视为人工次生湿地。还可积累养分、消除水污染、维持生态平衡等机能。有关资料研究表明,水田贮水能力可达170毫米以上,我省2000多万亩水田的贮水总量可达20亿立方米以上,相当一座蓄水20多亿立方米的大型水库,可相当于节省20多亿元水库建设费和减少
The development of paddy fields can not only increase grain production, but also be closely related to the natural environment to improve the ecological environment. Paddy field has a good water storage function, its water storage capacity is second only to the forest, can be regarded as artificial secondary wetlands. Can also accumulate nutrients, eliminate water pollution, maintain ecological balance and other functions. The data research shows that paddy water storage capacity of up to 170 mm above the province more than 2000 acres of paddy fields of water storage capacity of up to 2 billion cubic meters, equivalent to a storage of more than 20 billion cubic meters of large reservoirs, can be quite To save more than 20 billion reservoir construction costs and reduce
