In the second chapter description of PPS sample is given, which elementary area represents a combination of point sampling and line sampling. A shortened expression of such a sampling is, according to the author, PPS/p+1. In the third chapter the basic difference is shown between point sampling and line sampling. Thanks to this difference ,it is possible, by combining them, to attain maximal adaptation of the sample to stand conditions and estimation objectives. In the fourth chapter it is suggested that the collection of PPS/p+1 sample should be done by application of basal area factor 4, eventually 2, depending on stand density and stem diameter. The size of sample unit is mostly regulated by line length. In the fifth chapter, as an example, the numerical processing of PPS/p+ 1 sample in one stand is shown. 1991 Institut za šumarstvo PPS UZORAK, PRIKUPLJEN KOMBINACIJOM STAJALIŠTA (POINT SAMPLING) I LINIJE (LINE SAMPLING), U PROCENI INVENTARA SASTOJINE PPS SAMPLE, COLLECTED BY COMBINATION OF POINT SAMPLING AND LINE SAMPLING, IN ESTIMATION OF STAND INVENTORY
