黄河三角洲湿地生态特征变化及可持续性管理对策

Ecological Character Changes and Sustainability Management of Wetlands in the Yellow River Delta

近年来 ,由于农业市场化和产业化的发展 ,工业与城市化的崛起 ,黄河三角洲湿地生态特征发生了巨大变化。表现在湿地类型和面积的改变 ,湿地水状况及水质的变化 ,湿地产品的不可持续利用等。通过对湿地生态变化的自然因素和人为原因进行分析 ,提出了黄河三角洲湿地可持续性管理的方案 ,并从生态、社会、经济指标出发 ,探讨了湿地可持续性管理对策。

The paper presents several kinds of ecological character changes of wetands in the Yellow River Delta, including changes in wetland types and areas, changes in water condition and water quality, unsustainable exploitation and use for wetland products. The reasons of ecological changes are analysed, they is nature and man factors that induce wetland changes. Then the paper suggests a strategy about sustainability management for wetland ecosystem in the Yellow River Delta, and three countermeasures of sustainability management are proposed in the paper, they are, from ecological indices, mitigating, restoring and maitaining the function and process of wetland ecosystem; from social indices, solving the problems between wetland development and conservation; and from economical indices, dealing with the relationship between industry, agriculture and wetlands.
