Computing analysis and evaluation of water environment carrying capacity in Daqing area

In order to explore scientific, reasonable and sustainable ways to develop and protect water resources effectively and implement the effective and safe utilization of water resources, the water environment carrying capacity in Daqing area was analyzed and evaluated. A suitable evaluation indicator system was established according to the present status of the water environment in Daqing area. The carrying degree of each e-valuation indicator was obtained through the calculation of the established model. The water environment carrying capacity was obtained through the calculation of the water environment carrying capacity model. The main factors influencing the water environment carrying capacity were found through the analysis of the present status and dynamic changing tendency of the water environment carrying capacity in Daqing area. Results indicate that the water environment carrying capacity is relatively low and decreases with time in Daqing area, which is caused by short water resources and high utilization ratio of water resources.
