江汉平原地球关键带监测网建设进展

地球关键带是地球科学领域的热点研究主题,我国地球关键带研究尚处于起步阶段,如何形成符合我国实情的地球关键带调查与研究范式,仍需进一步探索。江汉平原地处长江中游,是长江经济带的重要组成部分之一,其主要特点在于受不同级次水利工程的强烈影响。基于多年调查研究,在江汉平原建立了一套较为完善的地球关键带监测网络,涉及水、土、气、生物等各地球关键带要素。监测网络设置上,既考虑了不同级次水利工程的影响,也考虑了区域营养元素/重金属的富集特征; 监测技术上,部分指标实现了原位监测,大部分指标实现了野外现场测试,未来将进一步加强在线监测并实现数据远程传输。目前,江汉平原地球关键带监测网已成功纳入全球地球关键带研究网络,这是我国地球关键带调查与研究的初步探索,不仅可为长江流域的地球关键带调查研究提供示范,也可为长江大保护战略提供有力的理论与方法支撑。

Progresses on monitoring network construction of Earth’s Critical Zone in Jianghan Plain

Earth’s Critical Zone is one of the hot research fields in Earth science. In China, the research of Earth’s Critical Zone is still in the initial stage, and how to form the investigation and research mode of Earth’s Critical Zone with Chinese characteristics still needs to be explored at present. Jianghan Plain, located in the middle reaches of Yangtze River, is an important part of Yangtze River Economic Zone, and it’s also under the influence of different scales hydraulic projects. On the basis of several years’ investigation, the authors have established a systematic monitoring network in Jianghan Plain, covering various elements of Earth’s Critical Zone, such as water, soil, gas and biology. In the design of monitoring network, they not only considered the influence of different scales hydraulic projects, but also the enrichment characteristics of regional nutrient elements and heavy metals. In the monitoring technology, they have achieved the in-situ monitoring of some indexes and the field testing of most indexes. The next work is to enhance online monitoring and achieve remote data transmission in the near future. At present, the monitoring network of Earth’s Critical Zone in Jianghan Plain has been successfully incorporated into the global Earth’s Critical Zone research network, which is a preliminary exploration for the investigation and research of Earth’s Critical Zone in China. This research can not only provide demonstration for the investigation and research of Earth’s Critical Zone in Yangtze River Basin, but also provide strong theory and method support for the great protection strategy of Yangtze River.
