Based on the establishment of fuzzy matter-element model,the paper selected 12 evaluation indexes, refered other documents and combined the actual situation of the study area to grade, and used the entropy method to calculate the evaluation index weight.The closeness between seven evaluated and standard samples was used to indicate the merits of evaluated samples so as to get the evaluated result of groundwater resources carrying capacity. Through calculating, the closeness between Yanliang, Lintong, Gaoling, Weibei industrial area,Ⅰ,Ⅱ,Ⅲgrade and the standard samples are 0.5359,0.7538,0.5926,0.6556,0.8635,0.6893,0.5508. The groundwater resources carrying capacity of Yanliang is in grade Ⅲ, the carrying capacity of groundwater resources is weak.The groundwater is in the state of high utalization and has small exploitation potential; The groundwater resources carrying capacity of other areas is in grade Ⅱand belong to general.The groundwater is in the state of moderate use and has a certain potential of exploitation. By comparing and verifying，the paper showes that the evaluated results of fuzzy matter-element model is reasonable and practicable. The method is simple and practical.
