摘要
针对水环境质量后评价对水污染防治和管理具有重要作用,提出了采用遗传算法优化投影方向,将地表水环境质量标准中的多个状态变量(高维数据)投影到一维子空间,建立了投影值与地表水环境质量评价等级关系,确立了适于地表水环境质量评价的投影寻踪模型,并应用于东明滩区安全建设工程地表水环境后评价中。结果表明,该方法能有效地对不同时期的地表水环境质量进行评价且便于比较,可为环境管理、环境规划及有关部门的决策提供依据。
Environment quality post-assessment of surface water(EQPSW) plays an important role in water pollution control and management.Projection direction optimized by genetic algorithm,high dimensional state variables of the EQPSW are projected to one dimensional subspace and the relationship between projecting values and evaluation grade of EQPSW is built.The projecting pursuit model is applied to EQPSW for safety construction in Dongming beach area.The results show that the model can evaluate the environment qua...
