摘要
通过对黑龙江农垦总局下属的6个灌区的各项功能参数指标资料的收集与整理,应用基于高维降维技术的投影寻踪分类模型(PPC),并采用微粒群算法(PSO)对投影寻踪模型投影方向进行优化求解,根据计算得出投影函数值的大小对各灌区运行状况进行评价,为灌区节水改造提供有价值的参考依据。
The single aspect status of irrigation scheme could be find from the single performance of irrigation scheme,but the holistic level comparison of irrigation scheme itself and among irrigation scheme was difficult in comprehensive evaluation of irrigation scheme.The paper collected and settled the each parameter index of the six irrigations in heilongjiang state farms bureau,the multi-dimensional dimension-reduction technology of Projection Pursuit Classification Model（PPC） using Particle Swarm Optimization Algorithm（PSO） to optimize their projection direction.The quality of the projection value of the irrigation scheme was appraised to make decision,provided the valuable reference basis for water saving reform.
