The freeze-up and break-up of ice cover on the reservoir is a popular natural phenomenon in cold region. Movement of the ice cover can damage the slope protection of the dam, causing losses in economics. Based on calculating and analyzing to the data of a decade observation on the ice cover formation and break-up on the shengli Reservoir, Heilongjiang Province, auther points out the characteristics of the ice cover movement and the distribution of peach-like pattern pressure field, and...

The freeze-up and break-up of ice cover on the reservoir is a popular natural phenomenon in cold region. Movement of the ice cover can damage the slope protection of the dam, causing losses in economics. Based on calculating and analyzing to the data of a decade observation on the ice cover formation and break-up on the shengli Reservoir, Heilongjiang Province, auther points out the characteristics of the ice cover movement and the distribution of peach-like pattern pressure field, and states the process of the ice thickening and vanishing, as well as the regularity of the ice cover activity. It can provide the scientific basis for the Shengli Reservoir engineering design and its ice-hazard protection.

寒区水库冰盖的生成与消失,是一种极其普遍的自然现象。冰盖的运动,常常破坏水库的大坝护坡,损失巨大。本文依据胜利水库冰盖生成与消失的10年观测资料,提出了冰盖运动以及相互作用和桃形压力场分布的特征,阐述了冰的增厚和消失过程及冰盖活动规律,对胜利水库工程设计和防冰害提供科学依据。

According to the statistics of Chinese glacier inventory, which was finished in accordance with the guidelines of world glacier inventory and published in 11 volumes with 21 copes, China has 46 298 glaciers with 59 406 km 2 of area and 5 590 km 3 of ice reserve. Glacier area in China accounts for 14.5% of the global and 47.6% of Asian mountain glacier area, respectively, that is to say, China is a country with best developed mountain glaciers in the middle and low-latitude. The glacier inventory...

According to the statistics of Chinese glacier inventory, which was finished in accordance with the guidelines of world glacier inventory and published in 11 volumes with 21 copes, China has 46 298 glaciers with 59 406 km 2 of area and 5 590 km 3 of ice reserve. Glacier area in China accounts for 14.5% of the global and 47.6% of Asian mountain glacier area, respectively, that is to say, China is a country with best developed mountain glaciers in the middle and low-latitude. The glacier inventory was compiled in accordance with the mountain systems and river systems. Some 14 systems are distributed from north to south in west China, including the Altay Mts., Tianshan Mts., Kunlun Mts. and Himalayas etc. Among them, the glaciers in five mountains, namely the Tianshan Mts., Karakorum Mts., Kunlun Mts., Nyainqentanglha Mts. and Himalayas, occupy 79% in area and 84% in ice reserve of the total in China, respectively. It is particularly worth noting that the huge west Kunlun Mountain has 6 580 glaciers with a glacier area of 10 844 km 2 , being the largest glaciated region in China. The glaciers in the interior region of China occupy 60% in area and 64% in ice reserve of the total in China, respectively. Among them the number of glaciers in the Tarim water system, dominated by the Tarim River and surrounded by the Tianshan Mts., Pamirs, Karakorum Mts. and Kunlun Mts., is largest, with area and ice reserve accounting for 56% and 65% of the total of the interior region, respectively. Glaciers of exterior region are located in the source area of the Yangtse River, Yellow River and the Yarlung Zangbo River etc. The glaciers in the basin of the Yarlung Zangbo River are most developed, their area and ice reserve occupy 61% and 70% of the total in the exterior region. Basins with a glacier area of more than 1 000 km 2 are basins of the Pumqu River, Yangtse River, Nujiang River and the upper Indus River etc. The glacier inventory data and the new knowledge about glacier and snow line elevation distribution have important scientific and practical significance to the water resource utilization and snow and ice hazard control in mountain regions in western China.

依据国际冰川编目规范完成的中国冰川目录 1 1卷 2 1册的统计 ,中国境内共发育冰川 4 62 98条 ,总面积 594 0 6km2 ,冰储量约 5590km3 ,是中低纬度山地冰川最发育的国家 .按山系和水系两种体系分别进行冰川编目 ,获得了中国西部及其各区域的冰川条数、面积和储量等多项指标的确切数量 ,发现了中国冰川及其雪线分布的若干新特征 ,这对于西部山区水资源的开发利用和冰雪灾害的防治等具有重要的科学意义和实用价值 .

Traditional manual control methods can not effectively meet the needs of the modern Yellow River water regulation system. Therefore, a self-tuning control model was developed for the Yellow River which uses adaptive control. The model seeks to protect the river basin system against dry-ups and ice hazards and to fairly allocate water. The important reservoirs of the Yellow River act as accumnlators in the system. The model can capture all the system information in a timely manner and adjust reservoir...

Traditional manual control methods can not effectively meet the needs of the modern Yellow River water regulation system. Therefore, a self-tuning control model was developed for the Yellow River which uses adaptive control. The model seeks to protect the river basin system against dry-ups and ice hazards and to fairly allocate water. The important reservoirs of the Yellow River act as accumnlators in the system. The model can capture all the system information in a timely manner and adjust reservoir discharges or water supply scheme to approach the desired targets. Calculated results for the 2001-2002 hydrologic year show that the model can automatically provide water allocation, runoff control and coordinated reservoir operation. The model is now in operation in the Yellow River Water Regulation Center.

为克服单纯人工调水的局限,满足现代黄河水调工作的需要,建立了黄河流域水量调度的自校正控制模型。以防凌、防断流以及"公平分水"为模型控制目标,以黄河干流骨干水库为调节器,及时跟踪、掌握水调系统控制流量、引水流量、水库泄量、水位等状态参数,调节水库泄流、调整引水计划。运用该模型编制了黄河流域2001至2002水文年的水调方案并与当年实际情况对比。结果显示与实际水调情况下的控制断面流量平均偏差1.05%,小浪底水库下泄流量平均偏差2.77%,各省区耗水量平均偏差4.40%,省区耗水过程偏差14.37%。该模型目前已经在黄河水量调度中心投入运行。
