A Study on Water Environmental Carrying Capacity of Typical Mining Area in Loess Plateau
[Objective] To recognize the water environmental carrying capacity in mining areas in Loess Plateau in order to use the limited water resources scientifically and efficiently.[Methods] Taking Gujiao City of Shanxi Province
a typical mining area in Loess Plateau as a case study
based on its hydrological
ecological
social and economic conditions
we selected nine evaluation indexes including utilization rate of water resources
per capita available volume of water resources
per capita water supply quantity
ecological water requirement quantity
water demand quota of lives
modulus of water requirement and supply
irrigation rate of cultivated land and water requirement quantity of industrial output per ten thousand yuan. We then constructed a quantitative model to evaluate and predict the water environmental carrying capacity in 2000
2010
2020 and 2030
respectively.[Results] According to the final integrated evaluation values in each year
the carrying capacity in the area was in moderate level
and weak and unsafe due to the scarcity of water resources water pollution and incomplete water-providing engineering constructions.[Conclusion] Some countermeasures were proposed for the development and utilization of water resources
including opening up the source and regulating the flow
the consolidation of foundation work
the consideration of ecological aims and so on
to improve water environmental carrying capacity in study area and other similar regions of Loess Plateau.
