防凌控制指标体系包括凌情发展指标、凌情稳定控制指标和凌情相应控制指标。凌情发展指标由水文站实测资料经统计分析得出；凌情稳定控制指标采用统计分析、经验公式推导、模型计算等方法，结合河道不同的边界条件提出河道适宜的封河流量、稳封期冰下过流、开河关键流量、适宜的槽蓄水增量等；根据以上分析并结合上游水库群及分凌区防凌调度方案、区间引退水等制定凌汛期全过程的凌情响应控制指标体系。", "ds_source": "
该数据集数据全部为水文站及水库实际观测资料经分析计算后的数据，包括封河时间、流凌及开河时间，水文站日均流量，实际发生冰塞冰坝的年份及灾情，水库防凌调度规则等。水文站及水库资料严格按照国家水文站观测规范要求进行观测，源数据主要来源于每年刊印的水文年鉴，购买自黄河水利委员会水文局，以及每年由黄河水利委员会正式刊印的凌汛总结。", "ds_process_way": "

The ice prevention control index system includes ice development index, ice stability control index and ice corresponding control index. The development index of ice jam is obtained from the measured data of hydrological station through statistical analysis; The flood stability control index adopts statistical analysis, empirical formula derivation, model calculation and other methods, combined with the different boundary conditions of the river, puts forward the appropriate river closure flow of the river, the under ice flow during the stable closure period, the key flow of the river opening, and the appropriate increment of tank storage; Based on the above analysis and in combination with the upstream reservoir group and the anti ice regulation scheme in the sub ice area, the ice jam response control index system for the whole process of the ice jam period is formulated.
