| The current lack of methods for analyzing the relationship between landscape structure and
function has led to a significant reduction in shrub area after evolution. This paper proposed an optimal
planning and simulation of spatial balance layout in regional shrub garden landscapes based on GIS models.
The regional shrub elevation data based on the GIS model was counted, and the thermodynamic entropy
of the shrub landscape was calculated in ArcGIS to judge the balance of the spatial layout. The distribution
uniformity of regional shrubs, the spatial balance of layout dominance and the dimension indicators of layout planning were analyzed, and the relationship between landscape pattern structure and function was
quantitatively analyzed. Through the optimal planning index of spatially balanced layout, the percentage of
regional shrub patch area in the total landscape and the shrub patch density index were calculated, and the
problem of low dimension in the planning process was solved through the interactive feedback of the GIS
model. Contrast, information entropy, and similarity between elements were used as description vectors,
combined with the maximum likelihood method for optimal layout planning, the comprehensive index evaluation
method was used to build a GIS evaluation model, and the layout standards were set according to
spatial balance to obtain reasonable planning results. The simulation results showed that the shrub area
was 5.0×105 hm2 after the method of shrub garden landscape layout planning and evolution, which was
consistent with the research method, indicating that this method was the most reasonable layout. |
