An Evaluation Method of Water Resources Carrying Capacity Based on Projection Pursuit Model

It is very important that drawing up a reasonable developing and utilizing plan for water resources and ensuring the sustainable supply of water resources to the socioeconomic development of an area. So that, how to analyze and evaluate water resources carrying capacity is the key issue. In this paper, we proposed an evaluation method for water resources carrying capacity in Yellow River Delta based on projection pursuit evaluation model and particle swarm optimization. First, we regarded economy, social development, ecological environment and water resources as a compound system and established an index system including eighteen indices. Second, we chose the data in 2010 and evaluated water resources carrying capacity in Yellow River Delta utilizing projection pursuit evaluation model and particle swarm optimization. Finally, based on the evaluation above, we can draw a conclude for several areas in Yellow River Delta. The water resources carrying capacity of Dongying district and Kenli County is better and is at level II, and water resources are in week stress-free state. And that the one of Hekou district, Lijin County and Guangrao County is medium and level III, and the development of water resources and social economy is in coordination state.
