摘　　要：基于水环境系统的多种不确定性共存的特征,利用盲数理论评价辽中地区矿业城市水环境承载力,促进该地区水环境与人类活动的协调发展。建立了水环境承载力评价指标体系,运用盲数理论将指标参数设置为盲数,对辽中地区矿业城市水环境承载力进行了计算。结果表明:1997-2005年,鞍山、抚顺水环境承载力属于临界安全,本溪水环境承载力属于较安全。通过与确定性参数情形下进行对比分析,水环境承载力盲数模型的计算结果是合理的,具有较好的适用性,具有推广应用价值。Blind number theory was used to evaluate water environmental carrying capacity （WECC） in mining cities of central Liaoning Province, P. R. China to prompt the balanced development of water environment with human activity. The research was based on the characteristics of water environment systems with numerous uncertainties such as random, fuzzy, and grey ones which may occur simultaneously or partially in a system. An indicator system for WECCs was established. The indicators were set as blind number and the WECC in mining cities of central Liaoning Province subsequently were calculated. Study results show that from 1997 to 2005, the WECCs in the mining cities Anshan and Fushun of central Liaoning Province were below the safe level, but the WECC in Benxi city was rather safe. By the comparative analysis of a system under uncertainty with that under a condition of certainty, the results of the blind number model regarding WECC was reasonable. This model is well adapted for WECC assessment.
