To live or develop sustainably, people must utilize
resources sustinably.And the term carrying capacity is just the
judgement whether resources wereutilized sustainably or not. i.e
The amount of resources consumed must notbe great than that of
environment could carry. This study was based on sustainable
development indicators to choose onesrelated to water
environment carrying capacity that defined as influenced by watr
quality, water consumption and land-use. The above chosen
indicators werelimitations that evaluate to compare the above
chosen indicators. For developingsustainably in any river basin,
we should try to promote the capacity to a satisfied level if
the real population of a river basin is great than the
population equivalent calculated by the above method. In our
case study, we only consider the following five aspects: the
classifiedwater quality standard of water body, municipal water
conumption, industrialwater consumption, the rate of an uptown-
commercial area to total area, the rateof an industrial area to
total area, the non-forest areas, and the divided numbers of the
changeable area. The final results show that the industrial
waterconsumption and the rate of an industrial area to total
area influence the population equivalent significantly, others
are not.
