Tang And Song Dynasties, The Taihu Lake Region Water Problem Research

From the Shih Rebellion to the demise of the Northern Song Dynasty, water conservancy construction in the Taihu Lake area had made outstanding achievements on the basis of the previous generation, greatly promoted the local social and economic development. Zhenjiang、Changzhou%Wuxi, lied on the northwest and the north of the Lake, was the jurisdiction of Runzhou and Changzhou, general Terrain of which was northwest to southeast. Terrain was relatively high. Major problem of the development of water conservancy in the region was the lack of water. The successful operation of key water conservancy project, especially Lian Lake, for Tang and Song rulers, effectively addressed this issue. Suzhou、xiuzhou which lied on the east of the Lake was the fastest growing region of water conservancy construction. The main problem of water conservancy construction in the region was the threat of flooding disasters. Because of the successful river governance, such as Wusong River, and the overall planning of polder water systems and innovative use of water technology tools, such as waterwheel、sluice, a large area of farmland had formed. Suzhou and Xiuzhou became the country show Range of important economic zone. Huzhou and Hangzhou lied on the south of Taihu Lake.there was a great number of mountains and abundant rainfall in this area. This led to the formation of the natural valley. When rainy season arrived, destructive of the floods was very large. When the rainy reason passed, water appeared to be valuable. Construction of dams, for flood control and irrigation, is necessary. Operating of West Lake and other large water conservancy construction and the polder system of local characteristics successfully solved the above problems. In addition, there was gradually perfect seawall construction around the Taihu Lake region. The using of engineering technology which met the scientific principles made our country’s Tong building technology increasingly rich.Tang and Song dynasties have attached great importance to water conservancy construction. Specific performance is not only two generations had the concrete laws and regulations which manages about the water conservancy facility and maintains, and had a set of official organization system which is responsible for management, maintenance, management of the hydraulic engineering. In concrete hydraulic engineering construction, regardless of the royal government or the place could consider the feasibility of the water conservancy facility, making the full feasible investigation before carrying on the water conservancy facility. During the Tang and Song, the major items of cost of building water conservancy projects in Taihu Lake region were labor compensation, material costs and land purchase costs. These funds’ origin may divide into three aspects approximately:people’s collection, financing of the local, central support. In terms of labor force use, the Tang Song ruler paid attention to do farm work in the right season. In the late Tang Dynasty, Manpower which were used for water conservancy construction mainly depended on commandeers, including army. But already had the trace to the employment direction. In the Northern Song Dynasty, There are three origin for the man-power which were used for water conservancy construction:expropriated porters, employed labor force, call soldiers, and the employment of labor force was more popular. In terms of working people, employment was better than force. In terms of government, employment was more efficient than forced labor. An important feature of the employment system was Work for the Dole. In addition, Examples that local powers led organizations of water conservancy construction were very common.Adequate labor force, attention and support of national policy were main reason that water conservancy construction of Taihu Lake in the Tang and Song dynasties had outstanding achievements. This times, the development of water conservancy construction in the region also had a profound impact for the development of region. paddy fields maintained high and stable yield, but there were significantly increased flood and drought disasters in Taihu Lake in the Song Dynasty. Taihu Lake water conservancy construction promoted the continued development of regional business, especially for Suzhou, Hangzhou. But development process also reflected Tang Song Empire intricate relationship between central and local. Long-term way of life closing to water promoted formation of water culture with local characteristics.
