摘　　要：根据石佛寺人工湿地的保护和管理目标,从生态系统特性、功能特性和扰动特性3方面出发,选取具有代表性的10个评价指标,提出5级评价标准来建立石佛寺人工湿地生态系统健康评价指标体系。石佛寺人工湿地生态系统健康评价模型采用模糊模式识别模型,各指标权重采用层次分析法确定。评价结果表明:石佛寺人工湿地生态系统健康状况为Ⅱ级,属健康状态,评价结果与实际情况相符。并对湿地健康状况进行了分析,为湿地管理和调控提供了科学依据。According to Shifosi constructed wetland conservation and management objectives, this paper establishes a health assessment index system of Shifosi constructed wetland ecosystem by considering eco-system characteristics, features and characteristics structure reflecting the Shifosi constructed wetland ecosystem. And based on the choice principle of assessment index, this paper chooses ten assessment indexes and advances five grade assessment. The fuzzy pattern recognition model is applied to the Shifosi con structed wetland ecosystem health assessment and AHP is used to determine the index weights. The result shows that the Shifosi constructed wetland Ecosystem belongs to the second standard （heahhy）. Compared with the actual condition, the result is reasonable. The ecosystem health evaluation and analysis result provides a scientific basis for the future management and regulation of wetlands.
