摘要
克服传统的TOPSIS法在确定指标权重以及贫信息决策等方面的不足,利用基于灰关联分析的加权TOPSIS法,建立评价模型,以水稻理论产量、产量构成要素指标、雨水总利用率、作物需水量、水分生产率、总磷释放量和氨氮释放量共10项指标为评价指标,对8个水稻控制灌排方案进行综合评价,结果客观可靠,为水稻灌排方案的优选提供了科学途径。
By using weighted TOPSIS method based on gray correlation analysis,which overcomes flaws of traditional TOPSIS method in deciding index weight and evaluating under poor information,an evaluation model is built to systematically evaluate 8controlled irrigation and drainage plans of paddy rice in consideration of 10 indexes including theoretical yield,yield components,rainfall utilization rate,water requirement of crop,water productivity,total phosphorus release and ammonia nitrogen release.The result is both accurate and reliable,providing a scientific way in designing superior irrigation and drainage plans of paddy rice.
