China "Tianhe" project start the demonstration route is expected to "air water"
"' Tianhe works ', if successful, is expected to cross-regional air water build North ' air corridors '. "Chinese Academy of Sciences, academician of CAs, Qinghai University President Wang Guangqian," Tianhe works "arguments said to start the meeting.
"Tianhe" project demonstration started and the first expert group meeting to be held from 9th to 11th in Xining city, Qinghai province, the joint team chaired by Tsinghua University and Qinghai University scientific research projects aimed at scientific analysis of water vapor distribution in the atmosphere and transport patterns and thus to take artificial intervention, between different geographical redistribution of the atmosphere, surface water resources.
Wang Guangqian, told reporters that the observations indicate, in the atmospheric boundary layer to exist within the stable and orderly in the troposphere water vapor channel, can be called "milky way", based on trans-regional water diversion patterns of air space is "milky way."
"We will be through to the water vapor content in the atmosphere and ' migration ' route monitoring, mastering water vapor ' migration ', and human intervention in conditional region, resolving the shortage of surface water resources in the North. "Wang Guangqian said.
Authority monitoring reports show that last more than 30 years, the main river runoff in North China overall downward trend, in 2025 there will be likely to face physical water scarcity. As one of the important strategic project, the East route, Middle has to a certain extent, ease the water shortage in North China, but the West due to the higher altitude, terrain and fragile ecological reasons, is still at the proof stage.
Chinese Academy of Sciences, Bao Weimin, Director of the science and Technology Committee of China Aerospace Science and Technology Corporation believes that "milky way project" and the future route of "air corridor" concept and helps to maximize the ecological benefit of the Qinghai-Tibet plateau and promote national economic and social development, especially in the North.
According to the plan, the "Thirteen-Five" period, "Tianhe" project is expected to annually in three rivers on the Qinghai-Tibet plateau, the qilian mountains, the Qaidam area increased by 2.5 billion, 200 million and 120 million cubic metres of precipitation, medium and long term are expected to achieve trans-regional water diversion 5 billion cubic metres per year, equivalent to about 350 water storage capacity of the Lake.

中国“天河工程”启动论证 南水北调有望“空中调水”
“‘天河工程’一旦成功，有望实现跨区域空中调水，构建南水北调‘空中走廊’。”中国科学院院士、青海大学校长王光谦在“天河工程”论证启动会上说。
“天河工程”论证启动会暨第一次专家组会议9日至11日在青海省西宁市举行，该科研项目由清华大学与青海大学联合团队主持，旨在科学分析大气中存在的水汽分布与输送格局，进而采取人工干预手法，实现不同地域间大气、地表水资源再分配。
王光谦告诉记者，观测结果显示，在大气边界层到对流层范围内存在稳定有序的水汽输送通道，可将其称为“天河”，基于大气空间的跨区域调水模式就是“天河工程”。
“我们首先将通过对大气中水汽含量及‘迁徙’路线的监测，掌握水汽‘迁徙’规律，并在有条件的地区进行人工干预，解决北方地区地表水资源短缺的局面。”王光谦说。
权威监测报告显示，近30多年来，中国北方地区主要河流径流量总体呈下降趋势，2025年将有可能面临物理性缺水。作为国家重要战略性工程，南水北调东线、中线工程已在一定程度上缓解了北方地区缺水问题，但西线工程由于海拔较高、地形复杂、生态脆弱等原因，尚处于论证阶段。
中国科学院院士、中国航天科技集团公司科技委员会主任包为民认为，“天河工程”及未来南水北调“空中走廊”的构想，有助于实现青藏高原地区生态效益最大化，促进全国特别是北方经济社会发展。
根据规划，“十三五”期间，“天河工程”有望每年在青藏高原的三江源、祁连山、柴达木地区分别增加降水25亿、2亿和1.2亿立方米，中远期有望实现每年跨区域调水50亿立方米，大约相当于350个西湖的蓄水量。
