摘要
针对洞头地区飞播造林的针叶密林,2009年采取"砍8 m、留4 m"的水平带状改造和3 m×3 m穴状改造2种方式,皆伐全部针叶、保留部分阔叶、补植乡土彩叶。结果表明:水平带状改造后,群落生物多样性、土壤理化性质都有一定的提高和改善;水平带状补植改造方式的景观改造效果快,穴状皆伐补植改造的景观改造效果自然。
Aiming at the density coniferous forest afforestated by aerial in DongTou, two improvement mode of horizontal zebraic and cave-shaped replanting were adopted in 2009. The clear-cutting belts of horizontal zebraic are 8 meters in width, which are interval arrangement in horizon with the retained belts of 4-meter-wide coniferous forest. The cave-shaped clear-cutting left a series of square shape with 3 meters side. In the two tending mode, all existing coniferous trees were chopped, part of existing broadleaf trees were reserved, and native color-leaf trees were replanted. As to the landscape improvement effect, the zebraic replanting have favorbale effect in a few years, and the effect of cave-shaped replanting was not artificial in visual sensation. After the horizontalzebraic improvement, the community biodiversity were increased, and the soil physical and chemical properties were improved.
