鄭白渠

Zheng Bai Qu，a large irrigation project in the ancient Guanzhong Region (today’s Shaanxin Province)，was the combined name of Zhengguo Qu and Bai Qu.(Qu means canal.)，now bore the name of Jinghui Qu.

鄭白渠是古代關中地區的大型水利灌溉工程，秦代鄭國渠和漢代白渠的合稱，近代陝西省徑惠渠的前身。

In 246BC during the Qin Dynasty Warring States Period，Zheng Guo，a hydrau-lic engineer from the Han State，began the construction of Zhengguo Qu for the Qin and finished the project in more than 10 years. The canal }nras 150 kilometers linking the Jingshui River and the Luoshui River. It could irrigate 40000 hec-of farmlands.

秦始皇元年(公元前246年)韓國水工鄭國主持興建鄭國渠，十幾年後完工。乾渠西起徑陽，引徑水向東，下游進人洛水，全長300餘里，灌溉面積4萬頃。鄭國渠的建成直接支持了秦國統一六國的戰爭。

Since then，the two canals were called by a joint name:Zheng Bai Qu. During the Tang Dynasty(618一907)，Zheng Bai Qu had three branches:Tai Bai Qu，Zhong Bai Qu and Nan Bai Qu，with an irrigation area of over 10,000 hectares. In the later dynasties，Zheng Bai Qu was revamped several times.

西漢太始二年，趙中大夫白公建議增建新渠，引徑水向東，至棟陽(今西安臨撞區東北)注於渭水，名叫白渠。乾渠長200裏，灌溉面積4500頃，此後灌區稱鄭白渠。唐代的鄭白渠有三條幹渠，即太白渠、中白渠和南白渠，灌溉面積超過10000頃，後來歷經各個朝代，不斷得到修復和發展。
