摘要
为了推动农业发展,对大型灌区节水改造效益进行评估。传统效益评估方法指标选取结果与评估方法适配性较差,导致评估结果可信度较低。针对此问题,设计基于i-Tree模型的大型灌区节水改造效益评估方法。对评估指标体系展开优化设计并计算其权重,结合i-Tree模型构建灌区节水改造效益评估模型。设定实验环节,对新型评估方法展开分析,经实验结果证实,此方法可避免传统方法应用性能问题的产生,提高评估结果可信度。
In order to promote the development of agriculture,the benefit of water-saving transformation in large-scale irrigation area was evaluated.The traditional benefit evaluation method has poor adaptability to the evaluation method,which leads to the low credibility of the evaluation results.To solve this problem,a benefit evaluation method of water-saving transformation in large-scale irrigation district based on i-tree model is designed.The evaluation index system was optimized and its weight was calculated.Combined with i-tree model,the benefit evaluation model of water-saving transformation in irrigation area was constructed.The experimental link is set to analyze the new evaluation method.The experimental results show that this method can avoid the performance problems of traditional methods and improve the reliability of evaluation results.
