| 摘 要： | 探讨了水资源可再生能力评价标准的建立。利用投影寻踪、遗传算法、倒S型曲线和水资源可再生能力评价标准,为水资源可再生能力综合评价建立了一种新的方法——遗传投影寻踪方法(GPPM)。给出了GPPM实施的步骤,并对黄河流域涉及的9个行政分区的水资源可再生能力进行了综合评价,认为黄河流域水资源总体上可再生能力较弱。GPPM的评价结果是实数值,具有直观性、有效性和通用性,可广泛应用于各种水资源综合评价问题。

| Abstract: | The assessment index system and standards of water resources renewability are established from a quantitative viewpoint.By using the projection pursuit,the genetic algorithm,the reverse S-shape curve and the assessment stardards of water resource reproducible ability,a new method for comprehensive evaluating water resource reproducibe ability,the genetic projection pursuit method (GPPM) is established,for which detailed steps are given,it is used to assess the water resources reproducible ability of the 9 administrative divisions along the Yellow River.The result shows that the water resources reproducible ability of the Yellow River is rather low.But the GPPM has visual,effective and well adaptative features,where the evaluation results are given with real number.It is a superior evaluation method to various water resource comprehensive evaluation problems. |
