四川冬水田的历史变迁

Historical Changes of Winter Paddy Fields in Sichuan

四川冬水田的发展史大致可分为清代的兴起与扩展,民国的继承与发展,新中国的改造与缩减三大阶段。水稻种植规模的大小、劳动生产率的高低、水利设施的多少均是影响冬水田发展的因素之一。以往提高农业产出的是改造冬水田的动因;现今提倡恢复冬水田又是出于其水利、生态湿地价值的考虑。冬水田作为一项大规模的水利工程,其之于四川农业、环境乃至气候的作用不容小视。

The development history of winter paddy field in Sichuan can be divided into three phases： the rise and extension in Qing Dynasty, the inheritance and development in the Re- public of China and new Chings reform and reduction. The influence factors to the develop- ment of winter paddy field include the size of rice cultivation, the level of labor productivity and the number of water conservancy facilities. In the past, the motivation of transformation of winter paddy field was to improve agricultural output. Comparatively, considering the value of wetlands and irrigation, government advocates the recovering winter paddy fields to- day. As a large scale water conservancy project, the role of winter paddy field to the agricul- ture, environment and even the climate in Sichuan should not be overlooked.
