摘要This paper presents an analysis of records obtained by video equipment of the 2001 Leonid meteor storm.
Totally 3712 meteors, including 22 non-Leonid ones, were recognized from the 247 minutes record.
The brightness of meteors was measured with the software "LIMovie" and a population index r = 2.01$\pm{0.05}$ (-8 $\le$ mag $\le$-3) was thus derived.
We proposed a way to derive the mass distribution index $s = 1.82$ from our one-station alone data.
The maximum of the activity appeared at $\timeform{18h25m }$ UT with an effective peak ZHR$_{90^{\circ} \times 67^{\circ}}$ = 52,606 (mag$\le$ 6.5).
There are also compatible sub-peaks and high plateaus aside the main peak.
One of them may correspond to the predicted 9-revolution dust trail (ejection in 1699).
In this article we treated the cross section of the influx zone as a trapezoid.
The peak "influx rate" generated by the 4-revolution dust trail (ejection in 1866) thus derived would be $6.76 \times 10^{-5}$ km$^{-2}$ s$^{-1}$ (mag$\le$ 6.5) and the corresponding "spatial number density" would be $9.52 \times 10^{-7}$ km$^{-3}$ (mag$\le$ 6.5).
