| [目的]对太白山森林公园的林内景观质量进行评价,为公园内森林景观的管理和规划提供决策依据.[方法]以太白山森林公园秋初林内景观为研究对象,运用心理物理学景观评价原理和数量化理论-Ⅰ统计学方法,对太白山森林公园林内景观的美景度进行了研究.[结果]在选取的10个评价指标中,枯枝和倒木、林下层高度、乔木枝叶整齐度、林下层整齐度、郁闭度以及树干形态6个因子对美景度的影响较大;而林下植被覆盖度、林木形态、地形变化以及胸径变异4个因子的影响较小.据此建立了林内景观评价模型,F检验证明所建立的模型是合理可行的(F=7.758>F0.05(38)=2.35).[结论]用统计学方法研究建立的太白山森林公园林内景观质量评价模型,对公园的景观质量管理,特别是制定不同林型的管理措施,以及对不同区域森林景观利用的评价具有一定的指导意义. |

| Abstract: |
| 【Objective】 The paper evaluated in-forest landscape quality of National Forest Park in Taibai Mountain to provide decision-making basis for the management and programme of the forest landscape in the park.【Method】 According to the landscape evaluation principle of mental physics and statistical methods of Quantitative Theory-I,the degree of in-forest beauty of main forest-type landscape of National Forest Park in Taibai Mountain was evaluated.【Result】 Litter and deadwood,the height of understory,uniformity of branch-leaf and understory,canopy density,and form of stem had significant effect on the degree of beauty.And the influences of coverage of undergrowth,form of forest,change of landform and variation of DBH were weaker.F test (F=7.758＞F0.05(38)=2.35) showed that the evaluation model was reasonable.【Conclusion】 The evaluation model is helpful to guide the management of landscape quality in the park,especially to draw up the management measures of different forest types and use the forest landscape in different areas. |
