| 摘 要： | 在剖析湿地健康水循环概念内涵的基础上,建立了湿地健康水循环压力-状态-响应概念模型,并运用此模型构建湿地健康水循环评价的指标体系。该指标体系探索了压力与湿地健康水循环变化之间的关系,并提出了相应的改善措施,有利于湿地管理工作的顺利开展。湿地健康水循环评价模型采用模糊模式识别模型,各指标权重利用层次分析法确定。根据评价指标的选择原则,选取9个评价指标,提出了5级评价标准,对扎龙湿地8年的湿地水循环状况进行了评价,明确各年的健康状况及限制因子。评价结果与实际进行对比分析,证明评价结果是正确的。

| Abstract: | Based on the analysis of healthy water cycle concept of wetland and its connotation,and the pressure-state-response (PSR)conceptual model for wetland healthy water cycle is proposed.The assessment indictor system for wetland healthy water cycle is established based on the model.The indictor system aims to explore relationships between the pressure and the wetland healthy water cycle change,and proposes the corresponding improvement measures.The fuzzy pattern recognition model is used to evaluate healthy water cycle of wetland,the calculating weighting method of each indicator is of analytic hierarchy process.Furthermore,the above theory and method are applied to the case study of Zhalong wetland to reveal their health grades and disadvantages.According to the choice principle of the indicator,the 9 indicators are selected.The five-grade assessment standard is adopted.The comparison shows that the evaluation result of this method is in accordance with the actual situation of Zhalong wetland. |
