    Hydrological Process Simulation Based on Statistical Simulation and Data Assimilation by YIN Jian, QIU Yuanhong, OU Zhaofan

    Published 2020-01-01
    “…In order to solve the load capacity calculation and performance optimization by modelparameter calibration, this paper realizes comprehensive optimization of hydrological simulationby taking the Shahe River Basin in North China as the research object and combining thedistributed time-variable gain hydrological model, the response surface provided by PSUADEplatform for parameter optimization, and the ensemble Kalman filtering for error correction & dataassimilation. achieves parameter calibration through using the observation of the outlet flow ofthe basin as the verification data, taking the Nash-Sutcliffe efficiency coefficient, waterbalance coefficient and their comprehensive functions as the evaluation targets, applying thestatistical simulation proxy model of the hydrological model generated by response surface method,performing a sensitivity analysis on the model parameters and reducing the value range, andadopting the global optimization method, and effectively correct the simulation of the runoffprocess in the river basin based on the remote sensing evapotranspiration observation, the ensemble Kalman filtering algorithm and the data assimilation of the hydrological model. …”

    Impacts of Future Climate Changes on Shifting Patterns of the Agro-Ecological Zones in China by Yingzhi Lin, Anping Liu, Enjun Ma, Fan Zhang

    Published 2013-01-01
    “…The shifting patterns of AEZs will be characterized by northward expansion of humid AEZs to subhumid AEZs in south China, eastward expansion of arid AEZs to dry and moist semiarid AEZs in north China, and southward expansion of dry semiarid AEZs to arid AEZs in southwest China.…”
