棋盘山风景区森林林内景观质量评价研究

以沈阳棋盘山风景区主要林内景观类型为评判对象,选取了52个典型的景观样本,采用美景度评判法进行评价,每个林内景观的喜好度值以标准化公式进行处理,在此基础上,运用多元数量化理论-Ⅰ的线性模型建立了棋盘山风景区森林林内景观的数量化评价模型。建模结果显示,影响该区域林内景观质量的主要因子依次为林下植被总盖度、树干形态、郁闭度、自然整枝、坡度以及枯树倒木。同时,将所得的数量化评价模型应用于实际评价中,所有景观样本的得分值总和为12.324,表明棋盘山风景区的森林林内景观质量总体上并不高,有必要进行林相的改造和建设。

Quality Evaluation of In-forest Landscapes in Qipanshan Scenic Area in Shenyang City

Collecting 52 representative photoes of in-forest landscapes,the forest landscapes in Qipanshan scenic area in Shenyang City were evaluated by adopting the method of Scenic Beauty Estimation(SBE) to acquire the likeliness values to each in-forest landscape and the scores were standardized.Based on the evaluation results,the empirical model between likeliness values and 12 landscape elements was established by using Polybasic Mathematical Theory I.The model showed that the factors which affecting the quality of in-forest landscapes most efficiently were coverage of ground plants,form of trunks,canopy density,natural pruning,degree of slope,dead trees and falling woods.Moreover,through using the judgment modl in practical evaluation,the sum of all the 52 landscapes was got,which was 12.324.The results of this study implied that the quality of in-forest landscapes in Qipanshan scenic area was not high,reformation and construction were very necessary.
