Abstract:

Previous literatures about ecological footprint and carrying capacity of water resources have little focused on classification of water resources accounts and its equivalence factor and yield factor. In this paper, water resources accounts are classified and region equivalence factor and yield factor are calculated to check ecological footprint and carrying capacity of water resources in Henan province in 2007. The results show that there are ecological deficits of water resources in most cities of Henan province, and the spatial differences also exist in ecological footprint and carrying capacity. In most cities of Henan province, ecological footprint of agricultural-forest-fishing is dominant, carrying capacity of underground water resource is primary in the south and west of Henan province, and carrying capacity of surface water resource is primary in the north of Henan province.
