Evaluation of Water Resources Carrying Capacity Based on Index System with Parameter Projection Pursuit Model——A Case Study in Shijiazhuang
摘要
Abstract
Shijiazhuang lies in the north of china which is seriously lack of water, and its water resources utilization always receives attention. The evaluation of water resources carrying capacity could provide advices for water resources utilization and planning in this area in future. Based on the specific conditions of water resources and the structural features of the index system in Shijiazhuang.18 indexes were selected to build the evaluation index system of water resources carrying capacity. The projection pursuit method was used to assess the model. Relying on the methods of normalization treatment, linear projection, constructing projection target function as well as optimizing projection target function, the selected indexes were analyzed using the projective pursuit method based on matlab platform. The results showed that the water resources carrying capacity level is grade IV in Shijiazhuang. The main indexes affecting the water resources carrying capacity included the basic farmland proportion, water-saving irrigation rate,effective utilization coefficient of irrigation water, utilization coefficient of available water resources, and water consumption of ten thousand yuan of industrial added value.关键词
