以次生林为主的自然风景林林内景观质量多处于中低状态，而调整改造的主要依据是林内景观质量的评价结果。笔者以吉林市大石门沟森林公园次生风景林为例，以美景度为目的指标，采用SBE法，应用相关分析、方差分析、逐步回归、聚类分析等方法，确定了次生风景林林内景观质量的主要影响因子，建立了质量评价预测模型，并对研究对象进行了景观质量类型划分。结果表明：树木姿态（ X4）、自然程度（ X17）、透视距离（ X16）和灌木高度（ X8）是影响次生风景林林内景观质量的主导指标，并建立美景度模型：MSBE＝－128?391＋15?63X4－3?615X8＋20?379X16＋17?933X17；美景度随树木姿态、自然程度和透视距离等指标得分值的提高而显著提高（ P＜0?05），随灌木高度的提高而显著降低（ P＜0?05）。根据聚类分析结果，将林内景观分为高、中、低美景度景观3种类型。针对研究对象的3种质量类型提出了调整结构、增强自然性、优化林相、适当控制灌木密度与高度等具体林分改造建议。
以次生林為主的自然風景林林內景觀質量多處于中低狀態，而調整改造的主要依據是林內景觀質量的評價結果。筆者以吉林市大石門溝森林公園次生風景林為例，以美景度為目的指標，採用SBE法，應用相關分析、方差分析、逐步迴歸、聚類分析等方法，確定瞭次生風景林林內景觀質量的主要影響因子，建立瞭質量評價預測模型，併對研究對象進行瞭景觀質量類型劃分。結果錶明：樹木姿態（ X4）、自然程度（ X17）、透視距離（ X16）和灌木高度（ X8）是影響次生風景林林內景觀質量的主導指標，併建立美景度模型：MSBE＝－128?391＋15?63X4－3?615X8＋20?379X16＋17?933X17；美景度隨樹木姿態、自然程度和透視距離等指標得分值的提高而顯著提高（ P＜0?05），隨灌木高度的提高而顯著降低（ P＜0?05）。根據聚類分析結果，將林內景觀分為高、中、低美景度景觀3種類型。針對研究對象的3種質量類型提齣瞭調整結構、增彊自然性、優化林相、適噹控製灌木密度與高度等具體林分改造建議。

The landscape quality of natural scenic forest mainly made of secondary forest was in a state of medium or low. The main basis of adjustment and transformation was the result of quality evaluation of in?forest landscape. A sec?ondary scenic forest at Corn?growing Ditch Forest Park’ s in Jilin City, Jilin Province was taken as an example in this study. The beauty degree was objective target and the Scenic Beauty Estimation ( SBE) method was adopted in this stud?y. Main factors affecting the landscape quality of the forest were determined through correlation analysis, ANOVA analy?sis, regression analysis and cluster analysis. At the same time, a prediction model of quality evaluation was established, and the types of landscape quality were devided. The results showed that the tree form( X4 ) , naturalness degree( X17 ) , perspective distance( X16 ) and the shrub height( X8 ) were the main indicators that influenced on the landscape quality of secondary forest. The beauty degree model was built:MSBE=-128.391+15.63X4-3.615X8+20.379X16+17.933X17 . With the improvement of tree form, naturalness degree and perspective distance’ s scores, the beauty degree improved signifi?cantly ( P<0.05) , and when the height of the shrub got higher, the beauty degree’ s level reduced significantly ( P<0. 05) . According to the results of cluster analysis, the forest landscape was divided into high, medium and low beauty de?gree of landscape. On the basis of three quality types of the study objects, the forest stand transformation approach were suggested, such as structure adjust, naturalness degree enhancement, forest form optimization, proper shrub?s density and height control.
