摘　　要：利用城市环境熵模型对2001～2005年石河子城市化地下水环境质量进行评价。结果表明,石河子城市化地下水环境熵值除pH值外,其他指标的城市化环境熵值均小于-1,表明地下水环境质量状况整体良好。挥发酚、氰化物、砷、汞、六价铬、铅、镉、铜、锌、铁10项指标城市化地下水环境熵值在2001～2005年呈逐年递增趋势,城市化地下水环境总熵值也呈递增趋势,表明城市化地下水环境随城市化进程有恶化的趋势。With the rapid development of China urbanization and global urbanization, water environment quality has become one of the main factors constrainted the urban development. In this paper, the author used the urban environmental entropy model to evaluate the groundwater environment quality of Shihezi city from 2001 to 2005. The results showed that all the groundwater environmental entropy values of urbanization were all less than -1 except the pH value, indicating that the groundwater environmental condition was good on the whole. The other 10 indexes of the groundwater environmental entropy values of urbanization, including As, Hg, Cr, Pb, Cd, Cu, Zn, Fe, etc, showed a continuous increase tendency from 2001 to 2005. At the same time, there was also an increasing trend in the total groundwater environmental entropy. From above data, we could see that the groundwater environmental system exhibited a downtrend with the progress of urbanization. We should constantly strengthen the dynamic monitoring of ground water to improve the efficiency of urbanization.
