Water conservancy was the lifeline of agriculture,and in the arid,drought-prone climate of Northwest China,water conservancy construction was a primary means of promoting agricultural develop-ment.The Huanghui Canal,completed in the early 1940s,was the first artificial gravity irrigation canal in Lanzhou.During its construction,major challenges such as insufficient funding,a shortage of skilled crafts-men,and a lack of raw materials signifiicantly affected the project's progress.However,with the active coop-eration of the local populace,the construction of the Huanghui Canal was ultimately completed successfully.Following its completion,the irrigated area's land productivity increased,the utilization area expanded,and the land value appreciated.The National Government even established a self-cultivating farmer experimental zone in the region,aiming to achieve the goal of"land to the tiller".The Huanghui Canal standed as a model of water conservancy construction in Northwest China during the Republic of China era.
