By using quantitative evaluation method, this paper examed the situation of the sustainable application of water resource in Wuhan city and found out the better and worse aspects in this city. The purpose is to provide the scientific basis for the sustainable use for Wuhan's water resources. The concrete steps are: firstly, the index system of evaluation is determined; secondly， the weight of each index is determined, and the indexes of each time period are arranged in order in their actual value and the comparative values are given out. Thirdly, the marks of each time are worked out by weighted sum (it also names the method of synthetically index). The end, the order of the water application level is worked out by comparing the marks of each time. By comparing with each index and analyzing the comparatively better and worse index within each time, the author gives a quantitative and overall evaluation. That is a quantitative evaluation.
