| 摘要: |
| 文章基于2012年10月和2017年7月两次林分空间结构与物种多样性调查数据，研究石门国家森林公园自然保护模式下的森林蓄积量和物种多样性变化。研究结果表明：与2012年相比，石门国家森林公园森林蓄积量明显提高，3块样地蓄积量分别增加5.96、10.63、13.2 m3/hm2，平均增幅达6.64%；物种组成基本稳定，增加3科5种；物种多样性指数增加，优势度指数变化不大。 |

| Abstract: |
| The dynamic change of forest volume and species diversity was studied for providing theoreticalguidance for sustainable forest management, based on two survey data in Shimen National Forest Park from October 2012 to July 2017. The results showed that the forest quality of Shimen National Forest Park was 32 signi?cantly improved, and the volume of three plots increased by 5.96, 10.63,13.2 m/ hm, with an averageincrease of 6.64%. The species composition was basically stable, and the number of families had been increasedby 3 families compared，and the number of species had increased by 5 since 2012. The variation of speciesdiversity was increased and the change of the J index was small. |
