      Yucheng Station has persisted in the construction of long-term observation field system and data observation, and obtained a large number of high-quality data. On the one hand, we have insisted on high-quality, uninterrupted long-term monitoring based on the established long-term observation fields; on the other hand, we have expanded the construction of long-term observation fields with regional characteristics according to the needs of research and discipline development.

      In our observation field system, there are 33 experimental observation fields, including 7 long-term CNERN observation fields. 28 fields are in Yucheng station and other 5 fields in Yucheng city, and the observation elements include moisture, soil, atmosphere and biological elements.

       The representative fields include: water surface evaporation observation field, large scale lysimeter, eddy covariance flux tower, Water-carbon-nutrient nexus field, critical zone soil and water processes observation field, pasture experiment field, Groundwater-Agroecosystem Experimental Simulator (Yucheng GAS), UAV comprehensive verification base.


      The observation fields of meteorology, water surface evaporation and crop water consumption have been in continuous operation for nearly 40 years; the observation field of soil nutrient balance has been in continuous operation for nearly 30 years; the observation fields of water and nutrient coupling, integrated observation field and volumetric evapotranspiration osmometer have been in continuous operation for nearly 20 years.

      According to the disciplinary development and research needs, eight long-term observation fields were established from 2013-2017.
