投影寻踪模型在污灌土壤污染分析中的应用
Application of Projection Pursuit Model to Analyze Soil Pollutants of Sewage Irrigation Region
摘要
Abstract
[Objective] The purpose of this project was to provide a scientific basis for preventing and controlling pollution by choosing different methods basing on particle swarm algorithm projection pursuit model analysis of farmland soil pollution. [Method] The sewage irrigation area from Shihezi city was chosen as the research object, surface soil was collected and various elements analysis was conducted. Through a number of indicators of soil contamination as projection parameters, the projection direction was determined. The projection index reflected the characteristics of pollutants in the soil of sewage irrigation areas. The method can avoid the artificial disturbance and acquire preferable effect. [Result] The results showed that soil pollution was mainly from nickel and chromium, and showed a tendency of soil sampling points reduction and soil environmental comprehensive quality deterioration. [ Conclusion ] This study determined the prevention and control of soil pollution in Shihezi River.关键词
