张掖黑河流域中游湿地现阶段监测体系建设构想

Construction Conception of Monitoring System of Wetland in the Middle Reaches of Zhangye Heihe River at Present Stage

黑河流域中游湿地地处青藏高原和蒙新高原的过渡地带,湿地类型多样、生物多样性丰富,其发挥的生态功能关系到整个西北地区的生态安全。通过分析张掖黑河流域中游湿地的概况及特点,提出了符合实际的湿地监测指标,分类确定了重点监测内容及其必要性。综合张掖黑河流域中游湿地的资源特点、水文状况、保护重点等,分析建立定位研究站、水资源监测点、植物及土壤监测点、鸟类监测点布局。论述了建立张掖黑河流域中游湿地生态系统监测体系的重要意义。

Wetland in the middle reaches of Zhangye Heihe River is located in the Qinghai-Tibet plateau and the transition of new plateau area, types of wetlands are various and biological diversity is rich, its ecological functions are related to ecological security of the whole northwest region. By analyzing general situation and characteristics of wetland in the middle reaches of Zhangye Heihe River, practical wetland monitoring indicators were put forward, and classification of key monitoring content and necessity were identified. Based on resources characteristics, hydrological conditions and priority protection etc. of wetland in the middle reaches of Zhangye Heihe River, layout of orientation research station, water resources monitoring point, plants and soil monitoring point and birds monitoring point were analyzed and established. The significance of building of wetland ecosystem monitoring system of wetland in the mid- die reaches of Zhangye Heihe River was discussed in this paper.
