黄河三角洲湿地资源地质环境评价与保护对策研究

Study on Geological Environment Evaluation and Protection Countermeasures of Wetland Resources in the Yellow River Delta

黄河三角洲是中国唯一一块保存最完整、最典型、最年轻的湿地生态系统,由于其地理位置优越、自然资源丰富等特点,在国际上备受关注。该文在已有资料分析、现场地质调查、遥感数据分析的基础上,构建了黄河三角洲湿地资源地质环境评价指标体系,采用定量与定性相结合的方法,将黄河三角洲湿地地质环境质量分为5个等级(优、良、一般、较差和差),研究结果表明,该地区19个县(市、区)中湿地地质环境资源质量为良的有8个,质量一般的为11个,总体处于健康-疾病的临界状态。并基于以上研究成果,针对性地提出了黄河三角洲湿地资源保护对策。

he Yellow River delta is the only one wetland ecological system in China with the characteristics of the most complete,the most typical and the youngest.Due to its geographical location and rich natural resources,it has attached great concern in the world.On the basis of existing information,field geological survey and remote sensing data analysis,the evaluation index system of wetland resources in the Yellow River delta has been constructed.By using the combination of quantitative and qualitative methods,geological environment quality of wetland in the Yellow River delta can be divided into five grades as excellent,good,general,worse and poor.As showed by the research results,the quality of wetland in 19 counties(cities and districts),8 belong to good grade and 11 are in general grade.Geological environment resources are generally in the critical state of health and disease.Based on these research achievemnets,countermeasures for prrotecting wetland resources in the Yellow River delta have been put forward.
