增进我国水资源利用的途径

This paper analyzes the status of abundance of water resource and adequacy of its monthly distribution in China through the yearly precipitation and monthly temperatures of January and July of several Chinese cities in comparison with those of various regions in the northern hemisphere of the world. Next it explains the right meaning of water resource of a region or a watershed and presents formulas for estimating the available quantities of local and alien water resources by discriminating between that available in nature and that economically utilizable to mankind. The utilizable water resource of a region is analyzed into three items: the local effective rainfall, the deep artesian water, and the feasibly introduced water from alien districts. Finally, it presents the four available means of accruement of water resource in China from analysis of the relations existing between the utilized quantities of water resource and the agricultural climate of the district as expressed in temperature, duration of sunshine and precipitation during the non-frost period.
