Study On Relationship Between Color Spatial Heterogeneity Of Planted Mixed Cotinus Coggygria Forests And Scenic Beauty Evaluation

Scenic forest is a high aesthetic value and to satisfy people aesthetic demand as the goal of forest. The beauty quality of the scenic forest can be reflected by color to a great extent, So this article from the perspective of color, Using the method of geostatistics, the changes of spatial heterogeneity between landscape forest photos were analyzed by different scales and light, find the appropriate scale of photos, and prove the importance of geostatistics in the photos selected. The main conclusions are as follows:(1) First of all, determine parameter value of photos color with different sizes and light using color values established Variation function model with different sizes and light Variance analysis of Nugget、 color value、Saturation、Value different scale and light showed that scale significantly effect on Nugget、color value、Saturation、value, light was not significant influence on you Nugget、color value、 Saturation、value By studying the nugget value change rule under different scale to determine t the scale comes to 1:162,which is suitable for researchers to take photos, is also a best picture framing.(2)The relationship between Color parameters and different sizes and light showed that Saturation spatial heterogeneity changes little in small scale, With the increase of scale is a sharp fall in the trend Under the small scale brightness showed a change trend of increase, With the increase of scale brightness values are gentle decline trend(3)Correlation coefficients of color parameter and SBE showed that values of base stations and diversity index had no significant correlation, SBE and nugget value showed a negative correlation, SBE and saturation, the color value and brightness were positively significant correlation.
