滨海核电厂的水资源论证中须考虑生态需水。水文学法宜用于对计算结果精度要求不高,并且生物资料缺乏的情况;栖息地评价方法宜用于生态保护目标为确定的物种及其栖息地;整体分析法宜用于流域整体生态需水评估。将生态需水分为天然生态... 滨海核电厂的水资源论证中须考虑生态需水。水文学法宜用于对计算结果精度要求不高,并且生物资料缺乏的情况;栖息地评价方法宜用于生态保护目标为确定的物种及其栖息地;整体分析法宜用于流域整体生态需水评估。将生态需水分为天然生态需水、功能生态需水、目标生态需水等类。水资源论证中的生态需水应为目标生态需水,应先获得生态保护目标,再确定生态需水。 展开更多

Water resource allocation (WRA) is a useful but complicated topic in water resource management. With the targets set out in the Plan of Newly Increasing Yield (NIY) of 10×1011 Jin (1 kg=2 Jin) from 2009 to 2020, the immediate question for the Songhua River Region (SHRR) is whether water is sufficient to support the required yield increase. Very few studies have considered to what degree this plan influences the solution of WRA and how to adapt. This paper used a multi-objective programming model for WRA across the Harbin region located in the SHRR in 2020 and 2030 (p=75%). The Harbin region can be classified into four types of sub-regions according to WRA: Type I is Harbin city zone. With rapid urbanization, Harbin city zone has the highest risk of agricultural water shortage. Considering the severe situation, there is little space for Harbin city zone to reach the NIY goal. Type II is sub-regions including Wuchang, Shangzhi and Binxian. There are some agricultural water shortage risks in this type region. Because the water shortage is relatively small, it is possible to increase agricultural production through strengthening agricultural water-saving countermeasures and constructing water conservation facilities. Type III is sub-regions including Acheng, Hulan, Mulan and Fangzheng. In this type region, there may be a water shortage if the rate of urbanization accelerates. According to local conditions, it is needed to enhance water-saving countermeasures to increase agricultural production to a certain degree. Type IV is sub-regions including Shuangcheng, Bayan, Yilan, Yanshou and Tonghe. There are good water conditions for the extensive development of agriculture. Nevertheless, in order to ensure an increase in agricultural production, it is necessary to enhance the way in which water is utilized and consider soil resources. These results will help decision makers make a scientific NIY plan for the Harbin region for sustainable utilization of regional water resources and an increase in agricultural production. 展开更多
