Abstract:

In order to increase the landscape quality of a mixed forest of Cotinus coggygria var. cinerea and conifers in Beijing lower mountainous area, the forest landscapes were evaluated by the scenic beauty estimation (SBE) method in this paper.The multivariate linear models between beauty degree and scenic factors of the out-forest landscape were established, and then the corresponding management measures were developed.The result showed that the ratio of sky in view had the largest contribution for the beauty degree of the mixed forest landscape, followed in turn by the sensibility of stem, ratio of colorful foliage, ratio of grayness, pattern of colorful foliage and variable hue of colorful foliage. Management measures for the mixed forest of C. coggygria var. cinerea and conifers should be adopted chronically, including cutting shrubs, thinning and filling plant in patches, to reduce the ratio of grayness, adjust the number of C. coggygria var. cinerea and conifers for maintaining the area ratio of red to green at 2:1, interplant other tree species with colorful leaves to make variability of hue, increase density of the landscape pattern distribution, and lead the landscape to mountain ridge. According to the BHD and CWD data of C. coggygria var. cinerea, Platycladus orientalis and Pinus tabulaeformis gained from a survey, the rational management density of pure forest of C. coggygria var. cinerea was found, and the rational number of C. coggygria var. cinerea and conifers was discovered for setting their area ratio of 2:1.

Key words: landscape evaluation, management technology, management density
