This paper probes into some problems related to the engineering programme, including co-ordination of supply and demand of water resources, quality-based water supply, self-supply water resources, drainage system, sewage treatment, municipal gas resources, short-term construction planning, planning scale and construction scale. 对于有关工程规划的一些问题进行了探讨,包括水资源的供需平衡分析、分质供水、自备水源、排水体制、污水处理、城市燃气气源、近期建设规划以及规划规模与建设规模。
Under the existing condition, we draw the conclusion that it will be an economical and practical approach to improve water price through market water price regulating mechanism, collocate water resource optimum, and attain water resource co-ordination of supply and demand. 研究得出,在现有的条件下,通过利用市场水价调节机制提高水价,从经济学角度实现水资源配置的帕累托最优化,使水资源达到供需平衡,是实现节水农业的经济和现实途径。
A power grid which has good structure can facilitate the realization of co-ordination of supply and demand of power, better optimize the power structure and achieve the mutual support between regional power grid. 一个良好的电网结构能方便实现电力的供需平衡,更好地使电源结构优化,实现区域电网之间的相互支援。
