Yucheng Comprehensive Experiment Station - China
Yucheng Comprehensive Experiment Station
The Yucheng Comprehensive Experiment Station (YCES) of Chinese Academy of Sciences (CAS) is located at the irrigation district of the Yellow River Basin in the Huang-Huai-Hai Plain, also called North China Plain. Physiognomy is characterized as hinterland covered mainly by fluvo-aquic soil (Fluvisol or cambisal) and salinized fluvo-aquic soil in the Yellow River Alluvial Plain. This region is dominated by warm-temperate semi-humid monsoon climate with ample energy and water resources. Historically, natural disasters such as drought, waterlogging, salinization, and wind erosion frequently occurred, resulting in vulnerable ecological environment and low grain production. Integrated improvements and managements were deployed in last several decades, and this region has become suitable for planting winter wheat, corn, cotton, and soybean with high yields in the Huang-Huai-Hai Plain. Research objectives and contents Objectives: regional sustainable agriculture rational utilization of natural resources such as water, land, climate, biomass, etc. Contents: conducting long-term observations and experiments understanding the mechanism of energy transfer and mass cycle in farmlands developing models from point to regional scales improving and developing instruments and measurement methods improving agro-ecosystem managements demonstrating research results and technologies Research achievements: Outstanding research results and massive experiment data have been achieved at the YCES. The achievements cover research fields of farmland evapotranspiration, crop water use, water transfer mechanism, experimental remote sensing techniques, regional agriculture demonstration, and technology transfer. More than 1,000 papers, 15 monograph books, and 5 data sets have been published. A number of awards were granted by national, CAS, and international academic organizations, for example, Agriculture Prize granted by the Third World Academy of Sciences Science and Technology Progress Award by Chinese Academy of Sciences National Top Award of Science and Technology Progress
General Characteristics, Purpose, History
Study on structure and function of farmland ecosystem at Huanghuaihai Plain; demonstration of sustainable agriculture; water cycling and balance; crops modeling; and applied remote sensing.
In 1966, the experimental zone for comprehensive managements of drought, waterlog, and salination in the Yucheng region was established. In 1979, the YCES of the Institute of Geography, CAS, was established. In 1983, the YCES became one of CAS stations. In 1987, the YCES became the Opening Key Experiment Station of CAS. In 1992, the YCES became the member of Chinese Ecosystem Research Network (CERN), as agro-ecological experiment station. In 1994, the YCES became the member of the Global Terrestrial Observing System (GTOS). In 1999, the YCES became a pilot agro-ecosystem station of National Field Scientific Observatory. In 2006, the YCES became a core agro-ecosystem station of National Field Scientific Observatory and Chinese National Ecosystem Research Network (CNERN).
