河北省重要自然湿地生态健康评价

Health Evaluation of Important Natural Wetlands Ecosystem in Hebei Province

以河北省重要自然湿地为研究对象,采用层次分析法,将湿地生态结构指标和功能指标作为综合评价层,13个生态单项指标作为具体指标层,建立河北省重点自然湿地生态健康评价体系。将湿地生态健康评价分为5个等级;很健康、健康、亚健康、不健康、疾病。通过湿地生态健康评价的计算与分析,结果表明,水源保证水平权重最大,洪水调节功能权重最小。河北省重要湿地生态系统主要处于亚健康、不健康和疾病状态,其中白洋淀湿地生态系统状况最好,黄盖淖湿地生态系统状况最差。

The important natural wetland in Hebei Province was studied through the analytic hierarchy process. By using indi-cators of ecological structure and function of wetland as comprehensive evaluation and 13 ecological indicators as specific indi-cators layer, ecology health appraisal structure of key natural wetland in Hebei Province was established. The health appraisal was divided into 5 ranks： very healthy, health, sub-health, ill health, disease. Through computation and analysis of health assessment of wetland ecology, the results showed that the weight of guaranteing water source was the biggest, and the weight of flood control function was the smallest. Important wetland ecosystem in Hebei Province was mainly under the sub-health, the ill health and disease conditions. Baiyangdian wetland ecosystem is under the best condition while Huang Gai Nao wetland ecosystem is under the worst condition.
