生物多样性的保护在很大程度上取决于人类对生物多样性的重视程度，除了生态和经济价值外，生物多样性往往还具有美学价值。然而，不知道平信徒是否欣赏物种的多样性，而不仅仅是某些个别物种或整个自然。我们通过一系列的实验和实地研究，研究了人们对物种多样性的感知和欣赏。我们提出了不同的物种丰富度和均匀度，但随机的物种组成的草地状阵列奠定了人们，并要求他们估计植物物种丰富度和排名的吸引力阵列。两个较大规模的实地研究，利用天然草地的实验进行了补充。无论是在实验和实地研究的平均感知的物种丰富度的人增加了真正的物种丰富度，但略有高估在低和越来越低估在高的多样性水平。外行人对实验草地阵列和天然草地的审美欣赏随着真实物种丰富度的增加而增加。由相同数量的物种组成的社区被认为是更丰富的物种，并赞赏更多时，他们的均匀度高。我们的研究结果表明，植物多样性本身对人类具有吸引力。目前由于加强管理而导致的草原多样性的减少，可能会降低那些以草原为主要景观特征的地区的吸引力。这可能对旅游业产生不利影响，并可能为保护草原生物多样性增加一个经济理由。(C)2009爱思唯尔有限公司保留所有权利。
The conservation of biodiversity critically depends on the value that humans attach to it. Apart from an ecological and economic value, an aesthetic value has often been assigned to biodiversity. However, it is not known whether lay people appreciate the diversity of species and not just certain individual species or nature as a whole. We studied in a series of experiments and field studies people's perception and appreciation of species diversity. We presented meadow-like arrays of different species richness and evenness but random species composition to lay people and asked them to estimate plant species richness and rank the arrays by attractiveness. The experiments were complemented by two larger-scale field studies using natural meadows. Both in the experiments and the field studies the mean perception of species richness by people increased with true species richness, but was slightly overestimated at low and increasingly underestimated at high diversity levels. Lay people's aesthetic appreciation of both the experimental grassland arrays and the natural meadows increased with true species richness. Communities consisting of the same number of species were perceived to be more species-rich and were appreciated more when their evenness was high. Our results demonstrate that plant diversity in itself is attractive to humans. The current reduction of the diversity of grasslands due to intensification of management may thus reduce the attractiveness of regions where grasslands are a dominant feature of the landscape. This could have negative consequences for tourism and may add an economic argument for the conservation of biodiversity in grasslands. (C) 2009 Elsevier Ltd. All rights reserved.
