- Abstract:
- As a gathering place of human production and life, Settlement landscape reflects the intensity of human space activities, reveals the mechanism of the formation and evolution of the human activity and formation of the landscape. In this paper, based on the ArcGIS and Fragstats software, setting granularity of 30, 100, 250, 500, 1 000 m, with RMA (the largest value method) and RCC (center property value method) for the principles, conducted space conversion to study the settlement landscape spatial distribution pattern of granularity conversion and mechanism. The results show that:(1) principle of RMA conversion to generate landscape area error is large, especially when the particle size is 1 000 m, traffic land disappeared, principle of RCC in space granularity transformation in the area of relative error is less and random; (2) the patch area of structure and spatial governs landscape type space granularity transformation of settlement landscape pattern; (3) patch number, patch density and aggregation index decreased, area weighted average patch fractal dimension increased, the largest plaque index rose after the fall with the increase of particle size, small patches by settlement landscape gradually into larger plaques, plaque forming degree and superiority degree increase; (4) the principle of the RMA settlement landscape transformation response was associated with spatial adjacency degree and area structure highlighting the overall distribution.
