The Tang Dynasty Xizhou Irrigation And Water Conservancy Research

Zhen guan fourteen years (A.D. 640 years), tang, then set up out west gaochang state (now, since then start a business in turpan), until An Lushan Rebellion outbreak in the west state.During this period,west state irrigation and water conservancy construction achieved rapid development. Western states have special geographical environment,?his region is the Asian inland, dry little rain, water seems particularly precious, the state government also attaches great importance to the construction of irrigation and water conservancy, management, have made a complete management system. West state water resources management is the"ShuiBu type"formulated according to the type of , also has its own unique irrigation system. the central government agency in tang dynasty water conservancy has two department managements; one is the YuanWaiLang &industry), ShuiBu; another is all ShuiJian. Both subordinate relationship is different, and they huave the same basically Responsibilities. The county and state officials, water conservancy competent staff appraisal of water conservancy repairs all states, under the supervision ShuiJian responsible for all. The tang dynasty bear by local state, irrigation and water conservancy works as the affairs of state of west DouDuFu management and a top manager, the west state water issues. In DouDuFu below, it also has "knows the water official" and "weir head", "knows the water people", and "water son" etc grass-roots management personnel.The development of a region water cause can not be finished in a short time, West state has been ruled han dynasty, wei, xijin dynasty, before QianQin dynasty, qian qing dynasty , houliang dynasty , xiliang dynasty, BeiLiang dynasty, hanShi regime, ma, zhang, qu yeast's gaochang regime . These regimes for later tang dynasty about agriculture, development of west state irrigation and water conservancy laid a foundation. In the western region to desert, caocao drought is its guarantee stable source of water, water conservancy construction is open and development of primary tuntian, the beginning of tuntian condition of the water conservancy development and promote. So in explore the construction of irrigation and water conservancy west state, must declare west state tuntian.Water conditions, geographical environment, and irrigation scale, decided on an area of farmland irrigation irrigation modes. Western states irrigation and water conservancy, basically adopt open channel irrigation and drainage well irrigation. Western states irrigation is mainly by snow-capped mountains melt water irrigation methods, therefore, it is mainly in open channel irrigation SunXiaoLin painted GaoChangCheng Mr Around the irrigation system in a picture of some shows. But west state special geographical environment, but also makes the west state irrigation and water conservancy entities small amounts of Wells canal irrigation.Farming civilizaFrom natural water to available water resources and conversion process added people's labor value. So, the collection of water resources tax was contemporary resource management commonly used. Water resources tax levied in irrigation water tax on most obvious. Ancient of farmland water conservancy projects funded by the government or collective organization construction, or that of farmland irrigation, improved production, TianZhu won the benefit, and to let irrigation engineering to continue to play a role, must collection certain taxes. Western states irrigation and water conservancy is no exception. In order to guarantee the normal operation of irrigation works, by western state government organization, and various industries, each national common we needed to repair the water conservancy facilities, this also can say is a kind of water conservancy corveetion period, agriculture is the basis of the whole social development. But in production technology is not developed, irrigation and water conservancy determines the agricultural development level.In tang dynasty, crops, economic west crop variety, market prosperity, all this leave the water conservancy was developed in the west state.
