通过在带岭林业实验局所做的人工林伐区生产试验,从作业成本、生态指标对5种人工林作业模式进行了分析与比较。在同等平缓坡条件下,模式Ⅱ无论是作业成本还是生态指标都明显优于模式I;在陡坡条件下,模式V比较经济。
Through the production experiment of cutting artificial forest in Zailing Forest Experimental Bureau, the operating modes of five kinds of plantations were analyzed and compared from the operating costs and ecological indicators. Under the same gentle slope conditions, Mode II is obviously superior to Mode I in terms of operating costs and ecological indicators; Mode V is more economical under steep slopes.
