摘要
为探讨野生植物的自然资源价值,基于能值理论估算了南岳衡山野生植物的价值,结果表明:南岳衡山野生植物由14个分布区组成,中日朝共有种种数最多,占28.90%,南岳特有种的能值-货币价值占总价值的98.53%,为最大;1422个植物基因贮藏能值-货币价值为97.399071×1013元,年贮藏97.399071×109元;单种能值-货币价值以南岳特有种最大,湖南特有种次之,依植物分布区面积的扩大而降低;生物多样性保护与管理,既要注重区域物种丰富度,更要注重生境狭窄种。
In order to study the value of natural resource of wild plants,the value of wild plants in Nanyue Mountains was estimated based on the energy theory.The results showed that：the wild plants in Nanyue Mountains were distributed into 14 areas.Among them,species distributed in China,Japan and North Korea count for 28.90%,which was the largest number of species;the energy-currency value of Nanyue endemic species was 98.53% of the total value,which was the highest one;the storage energy currency value of 1422 plant genes was 97.399071×1013 yuan with the annual value of 97.399071×109 yuan;the Nanyue endemic species had the highest energy-currency value for individual species,and Hunan endemic species were the second,the energy-currency value for individual species decreased as the distribution area increased.It was demanded to pay attention not only to the richness of local species,but also to the narrow habitat species for the conservation and management of biodiversity.
