【摘要】：三江源地區(qū)位于我國西部,是瀾滄江、黃河、長江的發(fā)源地,也是全國生態(tài)系統(tǒng)的天然屏障,具有重要的生態(tài)意義。利用1960~2013年三江源境內(nèi)13個氣象站點的月氣溫、降水資料,采用線性回歸分析、Mann-Kendall非參數(shù)檢驗、樣條函數(shù)插值法等氣候數(shù)理統(tǒng)計方法,分析了三江源地區(qū)氣溫突變前后三個源區(qū)降水空間分布特征,并針對氣候變化分別為三個源區(qū)提出可持續(xù)發(fā)展適應對策,結(jié)論如下:(1)三江源及其三個源區(qū)年及四季氣候均呈暖濕化趨勢。(2)三江源年氣溫發(fā)生突變后長江源北部降水明顯增多;春季氣溫突變后,瀾滄江源、黃河源冬南部降水明顯增多;夏季氣溫突變后,長江源北部降水明顯增多;秋季降水空間分布在氣溫突前變后變化不明顯;冬季氣溫突變后,長江源北部降水持續(xù)減少,黃河源東南部降水明顯增多。(3)氣候變化下瀾滄江源區(qū)可持續(xù)發(fā)展適應對策為合理使用水草資源、提高農(nóng)業(yè)生產(chǎn)集約化;黃河源區(qū)為控制源區(qū)人口數(shù)量、合理規(guī)劃產(chǎn)業(yè)布局;長江源區(qū)為建立三江源自然保護區(qū)的核心區(qū)、加大生態(tài)環(huán)境工程建設及治理力度。
[Abstract]:Located in the west of China, the source area of the three rivers is the birthplace of the Lancang River, the Yellow River and the Yangtze River, as well as the natural barrier of the national ecosystem, which has important ecological significance. Based on the monthly temperature and precipitation data of 13 meteorological stations in the source of the three Rivers from 1960 to 2013, the mathematical statistical methods of climate, such as Mann-Kendall nonparametric test and spline function interpolation, are used. The spatial distribution characteristics of precipitation in the three source regions before and after the temperature abrupt change in the source region of the three rivers are analyzed, and the countermeasures of sustainable development adaptation to climate change for the three sources are put forward. Conclusion: (1) the climate of Sanjiangyuan and its three source areas are warm and wet in the year and four seasons. (2) the precipitation in the north of the Yangtze River increases obviously after the annual temperature abrupt change in the source of the three rivers, and the precipitation in the southern part of the winter of the source of the Yellow River and the source of the Yellow River increases obviously after the sudden change of the temperature in the spring. After the sudden change of temperature in summer, the precipitation in the northern part of the Yangtze River increased obviously, the spatial distribution of precipitation in autumn was not obvious after the sudden change of temperature, and the precipitation in the northern part of the source of the Yangtze River decreased continuously after the sudden change of temperature in winter. The countermeasures for sustainable development of the source region of Lancang River under climate change are rational use of water and grass resources and intensification of agricultural production, and the source region of the Yellow River should control the population of the source area and plan the industrial layout rationally. The source area of the Yangtze River is the core area for the establishment of the Sanjiangyuan Nature Reserve, and the construction and management of ecological environment engineering are strengthened.
