摘要：

We present a QCD analysis of the proton structure function F-2 measured by the H1 experiment at HERA, combined with data from previous fixed target experiments. The gluon density is extracted from the scaling violations of F-2 in the range 2.10(-4) < x < 3.10(-2) and compared with an approximate solution of the QCD evolution equations. The gluon density is found to rise steeply with decreasing x.
