Abstract:

In order to study law of landscape pattern indices responding to surface roughness length and surface relief mountain factors spatial heterogeneity in the Wuyishan natural heritage vegetation landscape. With ArcGIS 9.0 and landscape index software, landscape indices at different surface roughness length and surface relief mountain landscape were studied. The results showed that curves of landscape area index, patch number index, landscape diversity index, landscape dominance index increased and then decreased, furthermore increased with increasing surface roughness length, the highest value accrue at 7 degree, landscape fragmentation index, fractal index of area and perimeter ratio showed ‘U’ type curves with surface roughness length increasing; landscape area index, patch number index, landscape diversity index, landscape dominance index increased and then decreased with the increasing surface relief. Only fractal index of area and perimeter ratio showed the lowest value at 800 m
