石门水库旱限水位（流量）分析

摘要

Shimen reservoir is the unique large (2) reservoir in Yingkou area ,which supplies the industrial and agricultural production and ecological water of Yingkou City,Dashiqiao City,Gaizhou City.Reservoir drought limit water level index is an important index for determining reservoir drought early warning level ,and an im-portant basis for starting the drought emergency response level.According to the data of Shimen reservoir site , it analyzes the reservoir inflow,water changed (including industry,agriculture,life and ecological water used);for the reservoir water supply capacity.it discusses and analyzes the lowest drought limit water level index un-der the condition of water demands ,which has very important significance on the operation of the reservoir , and provide scientific evidence of active drought ,to guide the development of industry and agriculture.%石门水库是营口地区唯一大（2）型水库，担负营口市、大石桥市、盖州市工农业生产及生活生态用水。水库旱限水位指标是确定水库干旱预警等级的重要指标，是启动抗旱应急响应级别的重要依据。根据石门水库建站以来的资料，分析水库来水量、用水量（含工业、农业、生活、生态用水）的变化，针对水库供水能力，探讨、分析石门水库在保证用水需求的情况下，最低旱限水位指标，对水库控制运用、科学主动抗旱提供技术依据，指导工农业生产发展具有十分重要的意义。
