Evaluation of Water Environment Carrying Capacity in Guanzhong Area

With the combination of real coded accelerating genetic algorithm and projection pursuit technology (RAGA-PP7), RAGA-PPT model for water environment carrying capacity (WECC) evaluation was proposed. Eleven comprehensive indexes were selected to form WECC evaluation index system, and the predicted value of each index in different development processes was acquired by system dynamics simulating. Based on the data, RAGA-PPT model was used to evaluate WECC of Guanzhong area at the year 1997, 2015 and 2020. The results show that waste water emission per person and available water supply per person are the key factors influencing FVECC of Guanzhong area, and the situation of WECC would be improved gradually, by taking measures of increasing the quantity of wastewater reuse and diversion water to improve water conservation and supply level.
