Abstract:

Supported by ARC/ INFO, using Spatial Correlation Indices of landscape structural components (SCI), this paper comprehensively analyzed the spatial relationship among landscape structural components of forest landscape in Guandishan Forest Region.The methodology of SCI measurement was explored and introduced.By integrated analysis, the key controlling affects of landscape spatial distribution pattern were explained, and general spatial distribution laws of landscape structural components were revealed in study area.The results showed that, SCI can be effectively used to analyze patterns of complex heterogeneous landscape.It generally presented explicit ecological meaning.Supported by ARC/ INFO, Unified network lan dscape sampling system was simple, convenient, reliable and practicable to measure the SCI.It was also showed that landscape pattern in study area was controlled by both environment heterogeneity and disturbance regime, which mostly come from residential area, extended along river and road corridor, and spread through farmland.From complex, fragmented and highly heterogeneous landscape, the distribution outline of all landscape structural components was revealed, and at the same time, the distribution pattern and general laws of ten forest types in study area, were also clearly explained in this paper.

Key words: Forest landscape, Landscape pattern analysis, Spatial correlation index of landscape structural components, Unified network sampling system, Guandishan Mountains
