摘要
以葫芦岛市红螺山地区为例,运用层次分析法和熵值修正法对整个地区的森林自然度进行量化评价,从树种组成、林分结构、林分活力、树种多样性、干扰程度5个方面,选择14个指标,综合评价出不同起源的林分自然度:天然实生>天然萌生>人工实生>人工萌生。
Huludao with Red snail mountain area as an example, AHP and entropy correction method for natural forests throughout the region to quantify the degree of evaluation, From the species composition, stand structure, stand vigor, species diversity, interference degree five aspects,Using 14 indicators, Evaluation of different origins stand naturalness：Natural seed ling〉 Natural sprouted〉 artificial seedling〉 artificial initiation.
