摘    要:针对森林物种多样性保育价值评估尚缺乏逻辑推理方法的现状,提出了更为客观合理的Shannon-Wiener指数评估法.此方法通过森林生态系统的Shannon-Wiener多样性指数和林分面积,计算其物种多样性保育价值.基于此方法,利用第六次全国森林资源连续清查数据和来自中国森林生态系统定位研究网络(CFERN)所属生态站的数万个观测数据,对中国森林物种多样性保育价值进行了计算.结果表明,黑龙江和云南两省生物物种保育总价值在全国名列前茅,海南省尽管单价最高,但森林面积较小,其总价值较低.广大西北以及华北地区森林平均单位面积价值和总价值普遍较低.将全国39种林分类型归为如下几类:单价高总量少型、单价高总量大型、单价低总量少型、单价低总量大型和中间类型,针对不同的类群采取不同的保护政策,有利于推动生物多样性保护工作.与目前流行的支付意愿法(WTP)相比,Shannon-Wiener指数评估法的优越性在于:以生态系统的自然属性为基础,每个指标都具有明确的意义,评价结果更接近理论认识,且结果之间可比性强.

关 键 词:Shannon-Wiener指数  森林物种多样性保育价值  中国

Abstract:Lacking of objective and logical2inference method for assessing forest species diversity conservation valueis an international p roblem. Based on Shannon-Wiener index, a new method was recommended. It p rovided animpersonal standard for the assessment. Forest species diversity conservation value in China was analyzed using thedata of the sixth forest continuous inventory from 1999 to 2003 and Chinese forest ecosystem research net stations.Results showed Heilongjiang and Yunnan p rovinces came out top as for the total forest species diversity conservationvalue. Although Hainan was the highest one as for the average value of unit area, the total value of it was lowbecause of the smaller total area. Northwest China and north China were lack of forest resources. The 39 stand typeswere divided into five group s: high average value of unit area and low total value, high average value of unit areaand high total value, low average value of unit area and low total value, low average value of unit area and high totalvalue, medium average value of unit area and medium total value. The classification would advance the species conservation work. Compared with theW illingness to Pay (WTP) method, which was the most popular one today,the advantages of thismethod was its basing on the natural characteristics of forest ecosystems. The average value ofunit area and total value were all have their physical meanings. The results were more coincident with theunderstanding and more comparable.
Keywords:Shannon-Wiener index  forest species diversity conservation value  China
