Abstract: Water shortage is an important constraint factor in the construction of the Three-North Shelterbelt (TNS). Here, we analyzed temporal-spatial patterns in water resources and trends in the Three-North region. We evaluated the water resource carrying capacity (WRCC) of 623 counties in the project area during the fifth phase of the TNS Development Program. Results show that 387 counties are appropriate for forestation, 185 counties can be planted, and 60 counties are inappropriate for forestation because of water resource constraints.

Key words: Three-North Shelterbelt, water resource, carrying capacity
