英文摘要	Low vegetation coverage and irrational land use are regarded as two main factors in influencing soil loss. In order to improve vegetation recovery and to adjust land use pattern on the Loess Plateau, the data of precipitation, net primary productivity of vegetation, and eco-water requirement of main crops of key counties on the Loess Plateau are used in this paper. The concepts of utilization/adaptation capability of eco-water requirement are used and plotted against mean annual precipitation in the 1960s to 1990s for vegetation and crops, respectively. Results demonstrate that in the regions with lower than 400, 400 to 510 and over 510 mm precipitation, the grass/shrub, grass/shrub/forest and forest fit to be planted, respectively. For crops in the regions with less than 300, > 310, > 450 and > 510 mm precipitation, Kaoliang and glutinous, millet, winter wheat, and maize are satisfied, respectively.
