| 摘 要： | 在三江平原低质次生林，应用效应带方式进行改造，并对其效果进行了分析，通过开拓效应带，营造红松人工更新层改造低质次生林，不同位置的幼树生长已呈现明显的差异：６ｍ宽效应带上栽植的３行红松功树中，中间行幼苗在高生长、地径生长等各指标上都呈现明显优势；其次是西行和东行，以保留带内栽植的红松幼树生长相对最差。效应带是改造低质次生林的有效措施。

| Abstract: | In this paper. the results of improving low-yield secondary forest in Sanjiang plain by the methods of making edge effect belt were analyzed. By making edge effect belt and afforesting Korean pine forest for reforming low-yield secondary forest. the growth of seedlings in different areas had significant difference. There are three lines Korean pine seedlings in effect belt with 6m width. Increment height and diameters of seedlings in the middle line were more dominative than those in other lines. However the growth of seedlings in the reserve belt was the most worthless. These results showed that it is significant effective measure to improve low-yield secondary forest by making edge effect belt. |
