摘　　要：通过将多目标决策-理想区间法与熵值法相结合，建立了基于运用熵权来确定权重的多目标决策-理想区间法，应用一种新思路评价福州市山仔水库1998—2002年富营养化程度。其结果表明，该方法可以有效地解决水库营养程度的优劣评价问题，且使评价过程大大简化，评价结果合理。By combining multiple objective decision- making and ideal interval method and entropy weight method, a new method of multiple objective decision making and ideal interval method based on entropy weight is set up. The new method is applied to assess the degree of entrophication of Shanzi reservoir. The results show that the new method can evaluate entrophication degree effectively. It simplifies the assessing process with reasonable assessment results.
