白龟山水库旱限水位的确定与应用

Determination and application of drought limit water level in Baiguishan Reservoir

白龟山水库是一座以防洪为主,兼顾城市生活工业用水、农业灌溉用水等功能的大(二)型水库,近年来由于极端天气频繁出现,干旱年景频现,白龟山水库流域遭遇连年干旱,给平顶山市工农业生产和居民生活用水造成了一定影响,依据《旱限水位(流量)确定办法》,对白龟山水库入库水量、城市生活工业用水、农业灌溉用水、环境生态用水、取水口高程等进行统计分析,采用两个月滑动计算的水库应供水量与死库容之和最大值所对应的库水位为依据,确定白龟山水库旱限水位,并经过了2014年大旱检验。

Baiguishan Reservoir is a large （II） reservoir which is based on flood control and has functions of applying urban domestic and industrial water, agricultural irrigation water, etc. Drought years are frequent in recent years due to frequent extreme weathers. Baiguishan Reservoir river basin suffers from droughts for many years, thereby leading to certain influence on industrial and agriculture production as well as citizen domestic water in Pingdingshan. The reservoir storage water quantity, urban domestic industrial water, agricuhural irrigation water, environmental and ecological water, water inlet elevation, etc. of Baiguishan Reservoir are analyzed statistically according to ＇ Method of determining drought limit water level （flow capacity） ＇. Reservoir water level corresponding to the maximum sum of reservoir supply water quantity and dead storage in two-month sliding calculation is adopted as the basis for determining the drought limit water level of Baiguishan Reservoir. It undergoes the test of drought in 2014.
