摘  要:
为了评价保护地水肥耦合效应,采用熵权法和TOPSIS法相结合,通过5个评价指标对东北春夏季保护地小区番茄不同灌溉上限(6.3,10.0,15.8 kPa)和施肥量(高、中、低)处理的试验效果进行综合评价。结果表明:综合熵权法和TOPSIS模型的评价方法可以用于多指标多方案的水肥管理的评价,在评价中指标的选取和待评价指标的权重是影响评价结果的关键因素。通过保护地水肥管理实例的评价,确定该研究水平下最佳的水肥管理模式为灌溉上限15.8kPa和高肥处理的组合。该评价方法模型计算简单,结果客观可信,适用性较强,为合理的水肥管理提供了科学依据,也可以应用到类似多指标多方案问题的评价。

摘  要:
In order to evaluate the coupling effect of better irrigation and fertilization scheduling in protected field,the research result of a plot experiment of different irrigation upper limit(6.3 kPa,10.0 kPa and15.8 kPa respectively) and fertilization amount(including low,middle and high)strategies of greenhouse tomato was evaluated by 5 indices and the methods of the combination of EW(entropy weight) and TOPSIS(technique for order preference by similarity to an ideal solution) in the arid region of northwest China during spring to summer.The results showed that TOPSIS & EW could be implemented as an effective method in the evaluation of irrigation and fertilization management with multi-indices and multi-project.In the process of evaluation,the choice of the indices and the weights of indices are the key factors which influence the evaluating results.The optimum strategy was the combination of irrigation upper limit 15.8 kPa and high fertilization by the evaluation of the protected field management example.The calculation of this model is simple and wide applicability,the results are objective and reliable,and the model can supply scientific basis for the optimization of irrigation and fertilization management,and the method has provided a reference for the similar evaluation problems.
