A process-based ecosystemmodel (Vegetationeatmosphere Interface Processes (VIP) model) is expanded, and then validated against three years’ biometric, soil moisture and eddy-covariance fluxes data over awinter wheatesummer maize cropping system in the North China Plain (NCP). The results show that the model is capable of simulating satisfactorily the(More)
Using 19 years of Chinese soil moisture data from 1981-1999, we evaluate soil moisture in three reanalysis outputs: ERA40, NCEP/NCAR reanalysis (R-1), and NCEP/DOE reanalysis 2 (R-2) over China. R-2 shows better interannual variability and seasonal patterns of soil moisture than R-1 as the result of incorporation of observed precipitation. ERA40 produces a(More)
Sustainable water use is seriously compromised in the North China Plain (NCP) due to the huge water requirements of agriculture, the largest use of water resources. An integrated approach which combines the ecosystem model with emergy analysis is presented to determine the optimum quantity of irrigation for sustainable development in irrigated cropping(More)
The characteristics of land surface/air energy translation was analysed on the basis of the observation data collected over a maize field in the North China Plain. The results indicated that the energy balance processes of land surface were greatly affected by the features of underlying face. Latent heat fluxes were the main component of land surface/air(More)
Understanding long-term vegetation dynamics, their responses to climate, and other driving factors is crucial for integrated basin management in the Mekong River Basin (MRB) in a context of global change. In this study, Normalized Difference Vegetation Index (NDVI) and climate data from 1982 to 2013 were collected from Global Inventory Modeling and Mapping(More)
Two sub-models were added to the developed soil-vegetation-atmosphere transfer model. Of the two sub-models, one was the canopy photosynthesis/stomatal coupled sub-model distinguishing the sun light and shaded leaves, and the second was the simplified growth sub-model considering growth respiration and maintenance respiration. The comparison of measured and(More)
Based on the Moderate Resolution Imaging Spectroradiometer (MODIS) - Normalized Difference Vegetation Index (NDVI), the Vegetation Interfaces Processes (VIP) model simulated the spatio-temporal patterns of actual evapotranspiration (ET) and the water consumption of different ecosystems in the Aksu River Basin, Northwest China between 2000 and 2015. The(More)
Evapotranspiration (ET) is a key ecological process connecting the soil-vegetation-atmosphere system, and its changes seriously affects the regional distribution of available water resources, especially in the arid and semiarid regions. With the Grain-for-Green project implemented in the Loess Plateau (LP) since 1999, water and heat distribution across the(More)
