边缘效应(Edge effect)的优势已被人们普遍认识。根据边缘效应的原理,运用“两行一带”的造林模式,人工建立长白落叶松4m、8m、12m带效应区,对其水分、土壤温度、土壤元素及生产力情况进行分析,得出结论:8m效应带是最佳选择。原因是它既能保证保留带林木的正常生长,又能为效应带创造优良的生态条件;既符合国家资源调查的有关技术规定,认定为片林,又能使林分达到生态、社会、经济三大效益的最佳结合。
The edge effect has been widely recognized. According to the principle of edge effect, using the “two rows and one belt” afforestation model, the 4m, 8m and 12m belt of the Larix olgensis plantation was manually established to analyze the water, soil temperature, soil elements and productivity and concluded that : 8m band effect is the best choice. The reason is that it can not only ensure the normal growth of the belt trees, but also create excellent ecological conditions for the effect belt. It not only conforms to the relevant technical regulations of the national resource survey, but also identifies the forest as ecological and social and economic The best combination of the three benefits.
