Adjusting water quantity is an important measure to resolve the problem. So, the author does an investigation on water resource of LIJIANG, calculates upper-water supply and requires equation. As a result, in the condition of no water adjust, and if in the extraordinary year of the lack of water quantity, the water flow will fade in 2010, and the demand of water quantity of 30 m~3/s in the season of the lack of water will not be satisfied. Based on the actuality of water resource, the thesis introduces the project of mending water reservoir to LIJIANG,analyzes its feasibility in the respect of technique and financial condition,brings forward major problem of the project. The result proves the benefit of the project in the field of environment,economy society is very prominent, and the project is an engineering to realize water resource of LIJIANG reasonable utilize; for the reason to guarantee this project to bring into play its function,it is time to carry out integrate management to water resource and water environment in LIJIANG valley.
