摘　　要：对扬州古运河风光带营建的生态保健型、生态环保型林地模式的环境效益指标进行了测定。结果表明:不同林地栽培模式在改变光照度、降低噪音、吸滞粉尘等环境效应上差异显著。林分内不同高度的光照度由林冠上层逐步向林地表面递减,林地模式的减噪功能与林冠的枝叶构成相关,林地树木的滞尘作用与叶幕的组成结构有关。Effects of forestland mode on ecological health and ecological protection along the Grand Canal in Yangzhou were studied. The results showed that there were significant differences in changing sunlight intensity, reducing noise, and accumulating dust in different forest land cultivation mode. The intensity of illumination of the different height decreased progressively from the upper strata of the crown canopy to the surface of the forestland; the function of reducing noise was combined with the branch and leaf compositions of the crown canopy; the dust accumulation function of the forestland trees was related to the composition structure of the leaf curtain.
