对于淡化水而言,其原水为海水,不管从绝对还是从相对角度来讲,海水都是非常丰富的,而且具有再生的性能,一个日产 20 万吨的海水淡化项目其海水来源是非稀缺的,对海洋及其周边没有影响,故可以认为其产出的淡化水的稀缺性价值为 0,即.当然,具体到某一地区可能会给海洋环境、生态循环等方面造成一定影响,在此要根据具体实例进行综合考虑.
海水淡化项目开发利用的前期费用,主要包括用于该项目取用海水资源的勘探、监测、项目规划以及相关科研管理等方面的费用,即:
保护在计算这部分费用时要特别注意两点:一是扣除计入淡化水工程成本的部分,避免重复计算; 二是这些费用中究竟有多少应该计入海水淡化项目,应确定一个合理的比例.
这里,我们以上海市为例.
依据对 2010 －2025 年上海市用水状况的分析,上海某公司海水淡化项目的日产淡水量为,日需海水量约为.
由于上海海水利用水源充足,其海水稀缺性很小,所以本文以海水利用的有用性价值作为基准.上海市位于沿海,利用某公司现有取水设备取水,某区沿海总水域面积为740平方千米,平均水深为8米,故可推算出该海域日平均海水保有量为,而该项目日需海水,仅为其总水量的0.0096% ,并且日排水量为,可见该项目取水对胶州湾总水量没有影响.该项目取水工程对生态系统的影响很小,基本不会对上海市的海域生态环境产生影响,其稀缺性价值可以归零.即.在这里,我们按 5000元计算.则该区域海水有用性价值为:RMB/
通过德尔菲法可推算出各类用水有用性修正系数:
[3]
则该项目淡化水有用性价值:RMB/
海水淡化水的资源价值主要由淡化水的有用性价值和稀缺性价值来决定,但是在海水转变为淡化水过程中,需要对其进行勘测、开发、保护等,这些费用都应当计入其资源成本中,根据相关资料,上海海水淡化项目的前期勘测、开发、保护费用总计约为 280 万元.以该项目运营期20年计,则RMB/
中间有些冒号之类的东西是公式,这里打不上去,其他的求翻译啊 ,

For the desalination of water, the water for the water, no matter from the absolute or from the relative perspective, seawater is very rich, but also has regenerative properties, a Nissan 200000 tons of seawater desalination project water source is not scarce, had no effect on the sea and its surrounding, so it is suggested that the production of desalinated water scarcity value is 0, i.e..Of course, specific to a region may cause a certain impact to the marine environment, ecological cycle, then according to the specific examples are considered.
The cost of desalination of sea water utilization project, including the project to take water resources exploration, monitoring, project planning and related scientific research management costs, i.e.:
Protection should pay special attention to two in the calculation of this part of the cost: one is deducted in desalinated water engineering cost, avoid repeated computation; two is how much of these costs should be included into the seawater desalination project, shall determine a reasonable proportion.
Here, we take Shanghai city as an example.
Analysis on the water status of 2010 2025 years in Shanghai city according to a company, Shanghai seawater desalination project to produce fresh water quantity, water quantity for about.
Because of the Shanghai sea by using adequate water, the water scarcity is very small, so the useful value of seawater utilization as a reference.Shanghai city is located in the coastal, using a water existing water equipment, an area of coastal water area of 740 square kilometers, the average depth of 8 meters, it can calculate the area average daily water quantity, and the project need water, only the 0.0096% of the total amount of water, and drainage quantity, the project of water has no effect on the total amount of water in Jiaozhou bay.Effects of the project of water project on the ecological system is very small, have basically no impact on the Shanghai sea area ecological environment, its scarcity value can be zero.That is.Here, we calculated according to 5000 yuan.The regional water useful value: RMB/
The Delphy method can calculate the usefulness of various water correction coefficient:
[3]
The project of desalination water useful value: RMB/
Seawater desalination of water resource value is mainly determined by the useful value and the scarcity value of desalination water to decide, but in the sea water into water desalination process, the need for investigation, the development, protection and so on, these costs should be included in the cost of resources, according to the related data, the previous survey, development, protection of Shanghai seawater desalination project a total of about 2800000 yuan.In the operation of the project period of 20 years, RMB/
