| 1. | As a basis for water allocation at basin level , the environmental water requirement is an important issue and should receive much attention 环境用水需求是一个重要课题,它是流域层面水资源配置的基础,急待开展大量的研究。 |
| 2. | It has an output capacity of 250 thousand cubic metres per day with provision for future expansion to 1 . 2 million cubic metres per day if demand goes up 滤水厂现时日产量为二十五万立方米,如果用水需求增加,将来最终可提高至一百二十万立方米。 |
| 3. | Firstly , this paper ensured the principles of supplying via variety sources to ensure the demands of city life , industry , and environment 首先确定西安市多种水源供水调配原则,以保证城市生活、生产和环境等用水需求为约束条件建立合理配置模型。 |
| 4. | These changes in agricultural water demands and soil - moisture levels had corresponding impacts on soil - moisture deficit , and consequently on agricultural production 这些农业用水需求及土壤水分含量的改变影响土壤缺水程度,进而影响农业生产的高低变化。 |
| 5. | We found a trend toward agricultural water demands increasing , soil drying and significant changes in soil - moisture variability on the north china plain and the northeast china plain 在中国大陆西北部,土壤水分含量呈现明显上升趋势,农业用水需求则明显下降。 |
| 6. | How timely carry on the well openting and closing operation according to the industry and inhabitant domestic water demand is the cost control key , and also is water management work focus 如何根据工业用水需求和市民的生活用水需求而及时地进行开停井操作是成本控制的关键,也是供水管理工作上的重点。 |
| 7. | In this way , it is expected that the supply - demand conflict of water resources in qyrid will be alleviated , and it is predicted that water requirement in agriculture in 2005 will be 25 % less 预测2005年农业需水量比现状可减少25 ,节约出的水资源量主要用来满足当地社会经济发展及生态环境用水需求。 |
| 8. | Through analyses price flexibility and price supporting capability of water use in different departments , estimates the potential of price adjusting in vary types water resource configuration 通过分析不同部门用水需求价格弹性和价格承受能力,按成本核算方法对不同类型水资源配置中的价格调节潜力做出估算。 |
| 9. | In order to get the result rational , the author introduced the theoretical basis , principles of the water pricing , and then laid special stress on analyzing the elasticity of demand and price of water for agriculture 为了使研究结果更加科学、合理,作者从理论的高度介绍了农业水价确定的依据、原则和方法,并进一步对我区农业用水需求价格弹性进行了研究和分析。 |
| 10. | Whether shortage of water resources is determined by two factors , water demand and water supply , is still uncertain . since it is also affected by runoff , rainfall and other randomized factors , so there are risks existing in the regional water supply system 水资源是否短缺是受供给和需求两个主要因素影响,当供给不能满足用水需求时,就会出现水资源短缺风险。 |
