摘要
在浙江省淳安、金华和东阳等地,采用典型选样法选取了30个生态景观林样地,调查测定森林景观效果及其构成因子。应用多元回归分析方法构建了森林景观效果与构成因子之间的相关模型,进行构成因子相关重要性排序。结果表明:树高、郁闭度、枝下高、草本层盖度、色调、树种组成、分布状况和采伐剩余物等8个因子与森林景观效果相关显著。在生态景观林发展中,应重点对这8个因子进行优化规划和经营管理。
As a special kind of the ecological public-welfare forest, ecological landscape forest plays an important role in improving ecological environment and landscape and developing forest recreation. Thirty plots of ecological landscape forest were selected in Chun＇an, Jinhua and Dongyang in Zhejiang Province by standard quadrat method, in which the forest scenery effect and their constitutive factors were measured. The linear-relation model between forest scenery effect and their constitutive factors were established. The results indicated that 8 factors exhibited clearly correlation with forest scenery effect, such as tree height, canopy density, clear bole height, cover degree of gress-vegetation layer, colour reaction of stand, species composition, distribution of trees and leavings of felling. These 8 factors in ecological landscape forest development should be emphasized.
