摘　　要：通过对凌河流域代表水文站的实测径流量和输沙量分析,得出凌河流域的水沙变化规律。探讨了凌河流域典型水文站（朝阳水文站）流域径流量、输沙量和含沙量的年内和年际变化趋势,比较了不同水文站径流量、输沙量和含沙量的年际变化。同时,探讨了凌河流域径流量、输沙量的沿程变化规律,并对大、小凌河流域的径流量和输沙量等水沙特性进行了比较。结果表明,凌河流域径流量和输沙量年内分配不均,多集中于汛期（69月）,且年际变化较大,径流量随沿程增大;而输沙量在山丘区随沿程增大,到达平原区随沿程减小。The water and sediment variations of Linghe River Basin were investigated based on the analysis of the measured runoffs and sediment discharges at the representative hydrometric stations along Linghe River Basin. The annual and interannual variation trends of runoff,sediment discharge and concentration at the Chaoyang hydrometric station were summarized,and the interannual variation trends of runoff,sediment discharge and concentration at different hydrometric stations were also compared. Meanwhile,the runoff variations along the Linghe River Basin were discussed,and the characteristics of sediment and water of Large Linghe River Basin and Small Linghe River Basin were compared as well.The results showed that in Linghe River Basin,runoff and sediment discharge is distributed unevenly within a year and mainly concentrated in flood season（ Jun.-Sep.）; the annual variation is significant,runoff increases along the way; while sediment discharge increases in hilly areas,and decreases in plain area.
