在分析深圳市城市森林现状的基础上,运用美景度评价法对城市人工林和天然次生林的林内景观进行景观评价,分析影响森林景观的主要因子,建立各类森林景观美景度模型,探讨主要构景要素与城市森林景观质量的关系。结果表明:深圳市人工林较天然次生林的林内景观质量高,人工林林内景观美景度平均值为0.092,天然次生林为-0.187。影响人工林和天然次生林林内景观质量的主要因子不同,人工林林内景观主要受林下层高度、层间植物丰富度、林木排列方式、枯树倒木、林下层统一度等9个因子影响,其景观模型是 SBE =0.131+0.177x5-0.195x8+0.208x9-0.162x10-0.129x12-0.00008x17+0.113x21+0.007x23-0.571x25;次生林林内景观主要受枯落物、郁闭度、通透距离等因子影响,其景观模型是 SBE =-2.016+0.157x1+0.215x4+1.753x16-0.063x18+0.021x24。
在分析深圳市城市森林現狀的基礎上,運用美景度評價法對城市人工林和天然次生林的林內景觀進行景觀評價,分析影響森林景觀的主要因子,建立各類森林景觀美景度模型,探討主要構景要素與城市森林景觀質量的關繫。結果錶明:深圳市人工林較天然次生林的林內景觀質量高,人工林林內景觀美景度平均值為0.092,天然次生林為-0.187。影響人工林和天然次生林林內景觀質量的主要因子不同,人工林林內景觀主要受林下層高度、層間植物豐富度、林木排列方式、枯樹倒木、林下層統一度等9箇因子影響,其景觀模型是 SBE =0.131+0.177x5-0.195x8+0.208x9-0.162x10-0.129x12-0.00008x17+0.113x21+0.007x23-0.571x25;次生林林內景觀主要受枯落物、鬱閉度、通透距離等因子影響,其景觀模型是 SBE =-2.016+0.157x1+0.215x4+1.753x16-0.063x18+0.021x24。

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.
