Controlled Drinage in Paddy Fields Based on the Projection Pursuit Model
JI Ya-hui · China Rural Water and Hydropower · 2011
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.
