针对中国水资源策略的行之有效的研究模型(英文)

从现在起到2025年,持续增长的人口、经济发展的需要和对环境保护管理的疏漏无疑会使中国的用水供求和水污染情况更为严重。因而对中国水资源的使用和挖掘制定一个行之有效的策略迫在眉睫。我们用模型推导出的水策略是包括水资源调度,海水淡化,水资源存储和水资源保护在内的四个方面的一个完整优化的规划和策略。首先,我们对中国到2025年的水资源供求关系做出预测。第二步,我们研究了水资源调度问题。先计算出了一条最短的管道,随后优化模型,通过计算每个缺水区域到每个多水区域的最短路径的总和排列出了优先考虑调度区域的顺序。再根据平衡分析的方法,总结出多水区域调度到缺水区域的顺序和具体的水资源量。第三步,我们考虑了海水淡化的方法。通过列出约束方程和使用一步反转模型,我们详细罗列了每个沿海区域在每个年周期内需要种植的用于海水淡化的大小植物的数量。第四步,我们通过物流与供应链管理探究了水资源存储的方法。第五步,则利用微分法和静态优化计算出在某个区域要种植用来净化水资源的植物的数量和具体污染问题能够被解决的年份。第六步,我们通过分层分析模型权衡了以上提到的四个方案的优先度。接下来,针对每一步建立的模型和方法,我们进行了评估,讨论,并提出了改进的余地。

Pratical and effective model for Water Strategy of China

China, the biggest developing country in the world, is having been challenged by the water strategy of numeric rising superpower. From now to year 2025, undoubtedly, a growing population and economic development as well as lax environmental oversight will increase water demand and pollution which will make the problem more severe. To work out how to meet water needs for 2025 in China, the model for water strategy our team establish is a whole optimizing and planning scheme concerning about 4 aspects （methods）： water storage, movement, desalination, and conservation. Before modeling, we redistrict China to 19 water regions for a better studying and analyzing of the problem along with the data of the following decade we anticipate. Then, we seperately apply distinctive models to each method to illustrate their specific advantages, related conclusions and viable strategies. Finally, the AHP Model, which takes reality and efficiency into account, tells us how to rank 4 methods from the top to the end by manifesting the relative weights of them and how great their economic impact, physical impact, cultural and environment impact is.
