th, the demand of water resource is
continuously increasing. That is to say water shortage has become a global problem. Water
resources carrying capacity is the basis and prerequisite of regional socio-economic development,
which is significant to realize the coordinated development of regional "water resources-
ecological environment-socio-economy" composite system. So it has become the focus and hot
topic in water science field nowdays.

duction in the area is
restricted by disadvantageous natural resources and environmental conditions,
including low arable land area per capita, frequent drought events and a landscape
dominated by mountains. Forage crop rotation systems could improve soil fertility,
increase crop外eld and provide quality forage supplies for livestock production.
Additionally, their adoption is considered a suitable means to advance sustainable
agriculture development. In this study, the role and status of forage crop rotations in
Tianshui city were studied.
