摘　　要：百色水库存在水温分层现象,为避免灌区工程取用低温水影响农作物生长,通过研究灌区内农作物灌溉适宜水温以及百色水库水温分布情况,应采取灌溉水温保障措施。经比选,推荐塔式活动孔口浮筒闸门分层取水方案,该方案可根据库区水位自动调节进水口浮筒闸门的高度,以保证取得库区表层水,满足作物对灌溉水温的要求。There exist water temperature stratification in Baise Reservoir.In order to avoid the use of low-tempera-ture water that may affect crop growth,taking Baise Reservoir Irrigation Zone Project as example,the proper water temperature for crop irrigation in the irrigation zone and water temperature distribution in the reservoir area were studied,based on which it was decided that irrigation water temperature guarantee measures should be taken.After comparison and selection of schemes,the recommended stratified water intake scheme is an intake tower accommo-dating a floating cylinder gate with adjustable orifice.This scheme can ensure the automatic intake of surface water in the reservoir area based on the reservoir water level,meeting the requirements of crops for irrigation water temperature.
