| 1 | 怒江流域悬移质输沙时空分布特征及变化趋势显示文摘利用怒江—萨尔温江上游地区怒江流域5个水文站长序列日悬移质输沙与径流观测记录,运用Mann-Kendall检验和R/S分析等方法,分析了50多年来(1956-2011)怒江干流和支流南汀河输沙时空格局和变化特征及其与径流的关系。结果表明:(1)怒江干流平均含沙量和输沙模数远小于支流南汀河,流域悬移质输沙率年际变异系数随控制面积增大而减小;(2)怒江干流木城站悬移质输沙率小于其上游道街坝站,部分泥沙淤积在区间河床可能是其原因之一;(3)怒江流域悬移质输沙年内分配极不均匀,干流悬移质输沙集中程度在月以上时间尺度高于支流南汀河,而在日时间尺度则低于支流南汀河;(4)怒江干流和支流南汀河悬移质输沙率均呈明显上升趋势,且未来仍将延续上升趋势,二者的突变分别始于1987年和1980年;(5)怒江干流中上游悬移质输沙与径流的相关性不显著,中下游、下游以及支流南汀河悬移质输沙与径流的相关性均显著。 | 刘新有 何大明 | 2013 | 地理学报2013，68，3： | 16 |
| 2 | 基于数字滤波法的怒江流域基流时空分异显示文摘为明晰怒江流域基流时空分异特征,利用数字滤波法进行怒江干流和南汀河支流的基流研究。结果表明:1怒江干流3站基流指数IBF在0.71~0.74之间,南汀河支流2站的多年平均IBF在0.68左右,南汀河支流IBF明显低于怒江干流,干支流基流量和IBF自上游向下游递增;2各站基流量与径流量变化过程基本一致,两者相关系数均在0.9以上;3怒江干支流各站多年平均基流量和径流量年内分配均呈'尖廋'的单峰形,而多年平均基流指数年内分配均呈'V'字形,但两者变化过程不完全相反;4怒江干流代表站道街坝站和南汀河支流代表站姑老河站IBF均为丰水年<平水年<枯水年,这与基流相对于径流更为稳定有关。 | 刘新有 谢飞帆 | 2017 | 水资源保护2017，33，1： | 11 |
| 3 | 云南气候环境变化对辣木种植产业的影响研究显示文摘以适宜辣木种植的气候环境条件为基础,采用云南各气象台站1959-2012年逐月的气象观测资料和数据,分析研究了云南气候环境变化对辣木种植产业的影响.得到的结果为:云南适合大面积推广种植辣木,但在不同的区域推广种植辣木,其气候环境的适应性差异则是比较显著的.因此,云南辣木种植产业的健康推进和理性发展,要以市场经济规律为基础,根据云南气候环境变化的时空特征和规律来进行科学合理的规划、引导和实施. | 尤卫红 郭世昌 | 2014 | 云南地理环境研究2014，26，5： | 2 |
| 4 | Variations and trends of trans-boundary runoff in the longitudinal range-gorge region显示文摘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 | YU Yan-ling PAN Feng LIU Xin-you CHEN Wen-hua HE Da-ming | 2017 | Journal of Mountain Science2017，14，2： | 0 |
