摘　　要：以生态优先原则、兼容性原则、最大值原则和水质为重点的原则,采用生态环境需水量计算法中的直接计算法、功能法及换水周期法,从林地生态需水量、草地生态需水量、人工河湖蒸发需水量、人工河湖净化需水量、生物栖息地需水量、人工河湖渗漏需水量、景观与娱乐需水量和公园内设施用水等八个方面,对济南市泉城公园的生态环境需水量进行了初步研究。结果表明,在2005年气候条件下,济南泉城公园的生态环境需水量大约为1.0467×106m3。在此基础上对提高泉城公园水资源利用价值及节约用水等方面提出了建议。This paper uses the direct computation method, function method and the water exchange cycle method which are all the computation methods of Ecological environment water demand to analyze the Spring City Park of Jinan from such eight aspects as ecological water demand of forest land, ecological environment water demand of lawn, the artificial river lake evaporation water demand, the artificial river lake purification water demand, the artificial river lake leakage water demand, biological habitat water demand, landscape and entertainment water demand and facility water used in park and preliminary calculated ecological environment water demand in Spring city park under climatic conditions of 2005. It considers four principles in computation which are Ecology first principle, Compatible principle, Maximum value principle and the water quality being the key principle. The computation result is that ecological environment water demand in Spring City Park isl. 046 7 × 10^6m^3. At last the author analyses the computation results and put forwards the proposal about water resources use value and saving the water used in Spring City Park.
