Effects of heavy thinning on ecosystem functions of mature Japanese cypress plantation

研究了重度间伐对75年古柏人工林生物多样性和生产力的影响。林下植被十分发达，净初级生产量约占人工林陆地部分的15%。然而，日本柏冠层关闭会降低林下植被的生物多样性。结果表明，重度间伐对生态系统功能的影响是暂时的，仅限15年。

We surveyed the effects of heavy thinning on biodiversity and productivity of 75 years old Japanese cypress plantations. Understory vegetation was well developed, which net primary production was estimated as 15% of terrestrial part of plantation. However, the canopy closure of Japanese cypress decreased biodiversity of understory vegetation. We concluded that the effects of heavy thinning on ecosystem function are temporal, which limited for 15 years.
