Figure 4: Impact of the number of indicators considered (multifunction effect).
Obtained composition of the landscape portfolios is relatively stable when using eight indicators or more. On the basis of four randomly selected indicators the average landscape composition is slightly less complex compared with that of landscapes that result from considering eight or more indicators. Random experiments with 10 repetitions with different indicator combinations for each size of the indicator set (4, 8, 12, and 16 indicators, all optimizations with uncertainty level fU=2.0) were carried out, with half of the indicators drawn from the ecological and half from the socioeconomic set. H stands for Shannon’s index computed for the average landscape composition.
