Abstract:

The important reason for ecological degradation in northern farming-pastoral ecotone is unreasonable and too intensive utilization of field water. Proper exploitation and utilization of field water is the key to develop agricultural production and restore ecosystem. This paper analyzed the research progresses in field water situation, the production potential, and new tasks facing the exploitation of field water potential. It also pointed out that the development and utilization must follow the principle for proper and rational usage. The basic connotation of proper exploitation of field water potential was identified preliminarily. The research framework and key scientific topics were put forward for the farming-pastoral ecotone of northern China. At present, we should guide the local agricultural production by the above mentioned principles, to restore ecosystem and to promote the sustainable development of northern farming-pastoral ecotone.

Key words: field water, production potential of field water, research progress, proper exploitation, research framework, farming-pastoral ecotone of northern China
