摘要
对１０年生和１８年生两片湿地松人工林进行不同强度的间伐试验，间伐３年后的结果表明：强度和中度间伐可明显促进１０年生林分胸径、平均单株胸高断面积和平均单株材积的生长；１８年生林分间伐效果则不明显；间伐林分每公顷胸高断面积增长量只有自然林分的７０％～８７％。
A trial with various thinning intensity was conducted in a 10 and 18yearold slash pine plantations. After 3 years, growth data showed that the effect of heavy and moderate on breastheight diameter,individual tree basal area of breastheight and individual tree volume in a 10yearold slash pine plantation was significant, but on that of 18yearold was not. The increase of basal area of breastheight in thinning stand per unit area was 70%～87% of that in no thinning stand.
