Jiangxi Province，located in the south bank of the middle and lower reaches of the Yangtze River，is a traffic location connecting the east and west as well as the south and north in the economic development pattern of the Yangtze River basin. By making the Ganjiang River and the Beijiang River join，the Jiangxi-Guangdong Canal connects the Yangtze River and the Pearl River systems to form a new north-south waterway. This paper analyzes the current conditions of water resources，studies and determines the major factors restraining water resources in the development of the Jiangxi-Guangdong Canal project. Additionally，a comprehensive utilization scheme is put forward for the developed water resources in the watershed section of Jiangxi-Guangdong Canal，which can provide technical support for scientific decision-making.
