摘　　要：为研究林窗对柏木低效林林下植物和土壤动物多样性的影响,2012年3月砍伐形成4种不同面积的林窗,并设置对照CK。2012年7月、2013年7月两次采用样方调查法以林下植物和土壤动物为研究对象对不同大小林窗进行生物多样性调查和分析,共记录植物12597株,分属30科51属54种;共记录土壤动物3189头,分属4门8纲23目。分析结果表明,随着林窗面积的增加,地上灌木植物与草本植物多样性呈递增趋势,而土壤动物多样性呈递减趋势;保育柏木低效林生物多样性,维持其生态系统稳定性的最适林窗面积在50 m2到100To study the influence of gaps on the understory plant and soil animal biodiversity of low-efficiency Cypress forest, felled to form four different areas of gaps,and set the CK in March 2012. Survey and analysis on the understory plant and soil animal biodiversity of different size gaps were conducted in July 2012 and July 2013. Recorded 12597 plants belonging to 30 families,51 genera and 54 species, and recorded 3189 soil animals belonging to 4 phyla, 8 classes and 23 orders. The results showed that with the increase of gap size, the shrub and herb species diversity showed an increasing trend, while the diversity of soil animals showed a decreasing trend;and the gap area of 50 square meters to 100 square meters was optimum to protect the biodiversity of low-efficiency Cupressus funebris forest and maintain the stability of ecological system.
