Study On The Surface Runoff Variations On Karashahar Basin

This study Based on the findings, Professor Hai Miti ? Yimiti "Bosten environmental changes and response to climate change" project, while the theory was drawing water, comprehensive basis for writing this paper, while more the actual measurement data based on the hydrological stations, hydrological data Yanqi Basin research, targeted research for multiple moving average index difference and the like Morlet wavelet, 54 years diameter Yanqi Basin since 1956 thereafter traffic changes were quantitatively analyzed. A total draw the following conclusions:Bayinbuluke hydrological station runoff variation: change flow seasons spring, ①summer, winter, the same trend, showed a downward trend in volatility, changes in flow rate fall is on the rise; spring flow decreased the most obvious. Flow change spring experienced volatility rises- Volatility fall- volatility rising stage; summer flow changes experienced increased slowly- slowly declining- volatility rising stage; autumn flow changes experienced volatility rise- a sharp decline- volatility rise, slow decline stage; winter traffic in the period 1956 to 2010 fluctuated upward flow, slow decline, fluctuations upward trend; seasonal flow variation difference in the ②spring, summer and autumn are basically the same, the larger the magnitude of the change. Winter in the difference between the almost constant. ③exist distinct seasons flow change cycle, analysis of variance and significance tests that: spring, summer, autumn and winter flow change existence 9a, 10 a, 9a and 8a of the variation cycle, the longest period in summer, the shortest winter.Dashankou hydrological station runoff variation: flow trends similar seasons, ①both trends tend to rise, which most obvious upward trend for the winter season. Four Seasons traffic fluctuated upward trend, winter flow rate of increase in recent years more and more significant. Traffic trends for the spring: volatility rises; summer flow trends: Volatility decline- increased volatility- a sharp decline; the flow rate change Fall trends: slowly declining- risen sharply- rising volatility; traffic trends for the winter: from 1956 has been slow to rise to 2005, the period 2006 to 2010 show a slow rise in traffic; the Four seasons in 1997 the most significant difference between the flow rate change. seasonal flow variation difference three ②quarters of a degree are basically the same, namely spring and autumn, the east quarter, while the difference between the most significant change occurred in the summer season. exist distinct seasons fl③ ow change cycle, analysis of variance and significance tests that: spring, summer, autumn and winter flow change existence 8a, 8a, 8a and 4a of the periodic variation, the shortest period of winter.Huang ditch hydrological station runoff variation: ①seasonal flow changes similar, there were increase in the state, and the upward trend was most obvious in spring season. Seasonal fluctuations in flow radiate upward trend in recent years, spring flow rate rises significantly. Spring flow changes experienced increased volatility- declined rapidly- rising phase fluctuations; changes in stream summer experienced a slow decline- the slow rise- a sharp decline phase; flow fall drop variation experienced fluctuations- increased volatility- a sharp decline phase; winter flow fluctuated decline- increased volatility- a sharp downward trend. 1995 seasons flow changes the most significant difference. ②seasonal flow variation difference three quarters of a degree are basically the same, namely spring, summer, autumn, and the difference between the most significant change occurred in the winter season. ③exist distinct seasons flow change cycle, analysis of variance and significance tests can be analyzed: spring, summer, autumn and winter flow change existence 8a, 6a, 9a and 3a of the periodic variation, the longest period in autumn, the shortest It is winter.Hydrological station runoff variation Kerr archaic: ①flow trends Seasons: spring, summer, autumn traffic trends consistent upward trend, winter flows downward trend in recent years, the rising speed of flow fall significantly. Spring flow changes experienced increased volatility- volatility decline- volatility rising stage; summer flow changes experienced increased volatility- volatility downward phase; flow rate variation autumn decline experienced volatility- volatility rising-slowly declining phase; winter traffic presented volatility rise- slowly declining trend. Seasonal flow changes the most significant difference between the year 1988. ② seasonal flow variation difference in spring, winter flow changes consistent flow change between summer and fall substantially similar. From 1956 to the spring, autumn and winter flow changes amplitude during 1964 consistent. exist distinct ③seasons flow change cycle, analysis of variance and significance tests can learn: four seasons(spring, summer, autumn, day) variation exists 9a, 6a, 7a and 7a of the periodic variation, the longest period in spring shortest summer.
