自然保护区森林健康评价体系的构建与应用

Establishment and application of forest health assessment system for nature reserve

自然保护区的森林健康评价有别于普通的森林健康评价,在评价中要考虑森林对自然保护区的影响。从森林对生态系统、森林社会价值、森林对珍稀保护物种影响等方面构建了自然保护区森林健康评价指标体系,得出自然保护区森林健康综合指数,从而判别自然保护区森林的健康程度,并对北京百花山国家级自然保护区的森林进行健康评价。评价结果表明,15块样地中,有8块样地处于健康以上状态,比例达到了53.3%,亚健康状态样地占到了46.7%,表明百花山保护区森林健康状况良好,与实际调查情况一致,表明指标体系有较好的适用性。

Different from the general forest health assessment,the forest health assessment of nature reserves must consider the impact of forests on nature reserves.The research established an indicator system from the perspective of impacts of forests on ecosystems,social benefits,and rare species and scored forest health of nature reserves.This indicator system was applied to assess the forest health of Baihuashan Nature Reserve in Beijing.The results indicated that 8 out of 15 sample plots in Baihuashan National Nature Reserve were healthy,accounting for 53.3 per cent.The sub-healthy plots accounted for 46.7 per cent.It showed that the overall health condition of Baihuashan Nature Reserve was good,and the indicator system presented a satisfactory applicability.[Ch,1 fig.3 tab.21 ref.]
