摘　　要：流域生态恢复潜力评估研究经常面临赋权方法选择问题,不同数据完整度情景选择合适的权重方法可以使评估结果更为准确。以小南海湖为研究对象,按照生态恢复潜力评估方法要求,分别选取层次分析法、熵权法、Critic法、因子分析法这4种赋权方法开展适用情景分析研究。结果表明,层次分析法适用于各评估指标客观数据不足需要专家主观经验判断的情景,熵权法适用于各评估指标间独立性较强且数据较多的情景,Critic法适用于各评估指标间联系清晰且数据较少的情景,因子分析法适用于数据同质化严重且评估指标选取过多的情景。该研究结果对于流域生态恢复潜力评估研究赋权方法的选择具有一定指导意义。Basin ecological restoration potential assessment research is often faced with the problem of selecting the assignment method,and different data integrity scenarios to choose the appropriate weighting method can make the evaluation results more accurate.Taking Xiaonanhai Lake as the research object,according to the requirements of ecological restoration potential assessment methods,the four empowerment methods of hierarchical analysis,entropy weighting,Critic method and factor analysis were selected to carry out the analysis of applicable scenarios.The results showed that the hierarchical analysis method was suitable for the scenarios where the objective data of the assessment indicators were insufficient and the subjective judgment of experts was needed.The entropy weight method was suitable for the situation where the independence of the assessment indicators was strong and there were more data.The Critic method was suitable for the scenarios where the connection between the assessment indicators was clear and there are fewer data,and the factor analysis method was suitable for the scenarios where there was serious homogenization of the data and the assessment indicators were too much selected.The results of this study are of some guidance significance for the selection of empowerment methods for the assessment of ecological restoration potential of watersheds.
