The Northern Jiangsu Canal Project And Agricultural Production During The Ming And Qing Dynasties

In the Ming and Qing Dynasties, the canal became the "lifeline" of the country.In order to ensure the smooth of water transport, to avoid the risk of the Yellow River, The government in the northern Jiangsu area has dug Jia River, canal and a series of canals, built gate dam, embankment, dam canal project. The water conservancy project although some are positive role of Jiangsu Province Water Conservancy and agricultural, but then everything is to transport center under the guidance of the concept, caused by the effect is more negative effects in the north of Jiangsu Province. Water conservancy project in the Ming and Qing Dynasties to change the regional water system, the regional flood is more heavy, and further cause the change of soil composition, land change, in order to adapt to the changes in the natural environment in Northern Jiangsu, the growing industry has also changed.This paper mainly in the Ming and Qing Dynasties in Northern Jiangsu canal project and its impact on agriculture as the research object. During the Ming and Qing Dynasties in Northern Jiangsu Province road transport, water transport heavy. But Huang Huai in the north of the entanglement intersection, so the regional water system disorders, complex water pattern. In order to protect the canal, Ming and Qing government to build a canal project in Northern Jiangsu area. Canal engineering construction not only changed the pattern of regional water system, resulting in regional flood and drought disasters, and construction of water conservancy projects occupy the land, resulting in the collapse of farmland waste. Water conservancy cause rivers, lakes and farmland and crop farming structure changes, further affecting the agricultural economic development. This paper from the water conservancy project study area in North Jiangsu Province during Ming and Qing Dynasties economy began to lag reasons and reflect the regional characteristics of Jiangsu Province.Through the discussion of the triangular relationship between Subei region water conservancy project and regional water system change and transition of agriculture, to study influence of North Jiangsu canal water conservancy engineering and agriculture environment. For water conservancy projects and regional agricultural environment between the "balance point" to provide certain reference significance.
