摘要

Based on the net income in Qinwangchuan irrigation region,the selection principle and adoption systems engineering analyses method were established throught a mathematical model.The problem of limited water's optimization in several crops and certain crop's area was discussed.The result of the optimal crops area in Qinwangchuan irrigation region was 5.066 × 104 hm2.Among them the optimal cropping area ratio of grain crops,economic crops and grass were 0.53:0.23:0.24.
