中文摘要：

多山的水文学过程通常显示出高变化到气候变化和人的行动。在纵的范围峡区域(LRGR ) ，西南的中国和东南亚洲人， transboundary 流量变化在气候变化的相互作用下面更敏感、复杂，走廊障碍在 LRGR 工作，并且建水坝造。在这份报纸，基于从三主流的长水文学记录(1956-2013 ) ，水文学在 Nu 驻扎河， Lancang 河，和红河，区域流量变化被分析。结果外面出现：我) 地区性的流量变化被走廊障碍功能强烈从西方在 LRGR 影响到东方，年度流量的可变性程度增加了，但是趋于；ii ) 三条河里的年度流量变化有高集中度；iii ) 在红河有 33 年 Nu 河和 Lancang 河，和 30 年里的流量变化的频率，并且更低的流动时期将在红河在 Nu 河和 Lancang 河里，但是仅仅为 4 年继续 8-9 年；iv ) 当 Xiaowan 和 Nuozhadu 的二个大水坝在 Lancang 河主流造了，自从 2010，他们年度流量的变化是相当不同的。研究结果能为地区性的水资源的持续利用，保存，和管理提供一个科学的底

英文摘要：

The mountainous hydrological process usually shows high variation to climate change and human action. In the Longitudinal Range-Gorge Region（LRGR）, Southwestern China and Southeast Asian, the transboundary runoff variations are much more sensitive and complex under the interaction of climate change, ＂corridor-barrier＂ functions in LRGR,and dams building. In this paper, based on the long hydrological records（1956-2013） from three mainstream hydrological stations in Nu River,Lancang River, and Red River, the region runoff variations were analyzed. The results show out： i） the regional runoff changes were strongly influenced by the ＂Corridor-Barrier＂ functions in LRGR from west to east, the variability extent of annual runoff increased, but tended to decrease after 2009 and the reduced extents also increased; ii） the annual runoff change in the three rivers had high concentration degrees; iii） there were periodicities of 33 years of runoff change in Nu River and Lancang River, and 30 years in Red River, and the lower flow period would continue for 8-9 years in Nu River and Lancang River but only for 4 years in Red River; iv） since 2010, as the two mega dams of Xiaowan and Nuozhadu built in Lancang River mainstream, their variations of annual runoff were quite different. The research results could offer a scientific base for sustainable utilization,conservation, and management of the regional water resources
