Abstract:

In this study, the scenic beauty estimation (SBE) method was applied to assess the within-forest landscape of the plantation and secondary forests by analyzing the present status of urban forests in Shenzhen. The major factors influencing the forest landscapes were analyzed and used to build the forest landscape model. The relationship between main landscape elements and forest landscape quality was also discussed. The main results showed as follows: The plantation had higher scenic quality of the within-forest landscapes in Shenzhen than the natural secondary forest, with SBE values of 0.092 and -0.187, respectively. The SBE value of Acacia mangium communities was the highest. The SBE value of Adina pilulifera+Psychotria yunnanensis+Acacia confusa communities was the lowest. The model for the within-forest landscape in the plantation was SBE=0.131 + 0.177x5-0.195x8+ 0.208x9-0.162x10-0.129x12-0.000 08x17+ 0.113x21+ 0.007x23-0.571x25. By this model, the major landscape factors affected the scenic quality of the inside forest landscapes were different between the plantation and the natural secondary forest. Within the plantation, the determinant elements mainly included understory height, abundance of interstratum plants, arrangement of trunks, the amount of fallen woods, uniformity of ground plants, stand age, branch height, coverage of ground plants and stand density. The model for the inside forest landscape in the natural secondary forests was SBE=-2.016 + 0.157x1+ 0.215x4+ 1.753x16-0.063x18+ 0.021x24. By this model, the main landscape factors affected the scenic quality of the inside forest landscapes were litter, crown density, viewable distance, bark's color and abundance of arbor.
