摘要: Abstract. Attributing changes in evapotranspiration (ET) and gross primary productivity (GPP) is crucial for impact adaptation assessment of the agro-ecosystems to climate change. Simulations with VIP model revealed that annual ET GPP slightly increased from 1981 2013 over North China Plain. The tendencies both were upward spring season, while they weak downward summer season. A complete factor analysis illustrated relative contributions climatic change, CO2 fertilization, management trend 56 (−32) %, −28 (25) %, 68 (108) %, respectively. decline global radiation resulted deteriorated aerosol air pollution was principal cause summer, warming intensified water cycle advanced plant Generally, agronomic improvements drivers crop enhancement.
