基于SOS-PP模型的城市集中式饮用水水源地营养状态评价
|
摘要
鉴于城市集中式饮用水水源地营养状态评价的重要性,以文山州暮底河水库水源地近3 a逐月营养状态评价为例,构建共生生物搜索(SOS)算法-投影寻踪(PP)营养状态评价模型对实例进行评价,并与模糊综合评价法评价结果比较。利用SOS-PP模型综合投影值计算分析暮底河水库近3 a逐月营养状态的变化趋势。结果表明:SOS-PP模型对实例营养状态评价结果与模糊综合评价法评价结果基本相同,暮底河水库近3 a营养状态呈中营养～中富营养;近3 a营养状态变化呈减弱趋势,但减弱趋势不明显。
Given the importance of nutritional status evaluation for urban centralized drinking water sources, water source of the Mudihe Reservoir, Wenshan Prefecture was chosen as an example to evaluate the nutrition status monthly in the recent three years. Therefore, a nutritional status evaluation model was built based on the symbiotic organisms Search(SOS) algorithm-Projection Pursuit(PP) for the evaluation of this case, and further its results were compared with the fuzzy comprehensive evaluation method. The monthly nutritional status of Mudihe reservoir for the recent three years was calculated and analyzed based on the comprehensive projection values from the SOS-PP model, and the variation tendency of the nutritional status was concluded. The evaluation results of nutritional status from the SOS-PP model were basically the same as the fuzzy comprehensive evaluation method. In the past three years, the nutritional status of the Mudihe Reservoir was moderate to moderate nutrient-rich, and the nutritional status showed a weak declining tendency.
