摘要
针对水稻田控制排水方案评价指标的不相容性问题,提出了水稻田控制排水方案综合评价的RAGA-PP方法,并运用该方法对水稻全生育期内蓄水条件下16种不同控制排水方案进行了综合评价,评价结果很好地反映了各项评价指标对综合评价目标的贡献大小以及各种控制排水方案的优劣,对农业生产实践起到一定的指导作用。
A new method,projection pursuit based on genetic algorithm,is used to comprehensively evaluate the project of controlled drainage in paddy fields for solving the incompatibility of evaluation indexes.And the method is used to comprehensively evaluate 16 different schemes of controlled drainage under the condition of water storage during the whole rice growth period,and the results of the value of every index and the advantage of every scheme of controlled drainge accord with practice,it is significant to instruct the agriculture production.
