다국어 초록 (Multilingual Abstract)

This paper examined the change of the leaders who constructed water conservancy facilities and who managed them in the Changjiang(長江) area during the latter half of the Tang Dynasty. After Anlushan(安祿山) rebellion, the Tang regime started to financially depend on Changjiang area. There was a considerable development in agriculture and irrigation, which led to the increase of irrigation and drainage facilities, and to the importance of Grand Canal. The Tang regime had actively encouraged local officials, such as governors of county and prefecture, to construct a lot of irrigation and drainage facilities, waterway and watergate, and to manage them well. This trend had lasted until Xiantong(860-873). Therefore, this made local officials who performed the will of the Tang regime as the leaders of water conservancy construction and management in Changjiang area. Administrative management of water control was very important because there were some sort of conflicts in using water conservancy facilities. Many regulations in water control were intended to lead to more fairness. The water control of Qiantanghu(錢塘湖) in Hangzou would be also handled fairly by going through the normal process. However, the regional powerful persons usually tried to monopoly the water, and to transform a small part of the lake to arable land. The related civil suits to use the water of Lianhu(練湖) in Runzhou(潤州) was a typical example of water rights dispute. In accordance with the weakness of administrative power of the Tang regime, the regional powerful persons such as Yezairong(葉再榮) in Yuezhou(越州) and Luguimeng(陸龜蒙) in Suzhou(蘇州) constructed small dams, and autonomously managed them. In conclusion, the leaders of construction and management of water conservancy facilities were changed into regional powerful persons from local officials. They were rising to the leaders under the ‘Cultivation of Changjiang area’.
