英文摘要	By using MODIS data products, combined with DEM data, land use data, meteorological data, employed SEBAL model, light use efficiency model, PAR model and the algorithm of vegetation index, the parameters of ET(Evapotranspiration), NPP(Net Primary Product), PAR (Photosynthetic Active Radiation), NDVI (Normalized Difference Vegetation Index) and EVI (Enhance Vegetation Index) in Haihe River Basin were estimated. The impacts of elevation and land cover change on ET, NPP, PAR, NDVI and EVI are analyzed. We found that the impacts of elevation and land cover change on parameters are significant. The conclusions are as follows: 1) The ET in areas below 500m is the biggest, the ET in areas above 1500m is bigger and the ET in areas between 500-1500 is the smallest. 2) The impacts of location and elevation on PAR are significant, the PAR in areas with lower elevation is smaller; with the rising of elevation, the PAR has a increasing trend. The difference of PAR in different land cover is caused with location and elevation. 3) The NPP, NDVI and EVI in areas between 20-800m are bigger, and the values of these parameters in others areas is smaller. 4) The NDVI, EVI and NPP in areas covered with farmland, grassland and forest are bigger, and the values of these parameters in areas covered with unused land, water body and built-up land are smaller.
