漓江上游森林小流域径流过程及其影响因素

Abstract

Abstract:

In this paper, runoff processes of a small forested watershed in upper reaches of Lijiang River were in situ monitored and the relationships between runoff and influencing factors were studied from January 2009 to December 2011. The results showed that the precipitation distributed irregularly within a year and there were obvious differences in precipitation amount among years, which resulted in great runoff fluctuation and inter-annual variation in Lijiang River. Summer runoff accounted for 63.2% of the whole year's and winter runoff accounted for 9.2%. The runoff coefficient of the whole watershed was 0.664 2. The precipitation effect on river runoff was accumulated with multiple rainfall events, which resulted in a lag of peak runoff behind the precipitation. Runoff period is usually longer than the precipitation's. The runoff would extend to 20 days for 18 days' continued rainfall. The impact of rainfall on runoff decreased in non-linear with the extension of time after rainfall event. The accumulation of lagged runoff can reduce the function of forest on hydrological regulation and might result in large runoff under light rainfall in rain season.

Key words: Lijiang watershed, forest, precipitation, runoff
