《日本维管植物红皮书》是根据它们的灭绝风险编写的。为了建立这个列表，我们使用种群数据和大约4400个网格的下降率对2000个分类群进行了评估，每个网格大约100公里。该数据库可用于估计人类活动对受威胁植物灭绝风险的影响。为了评估灭绝风险并将评估应用于保护行动，贴现平均灭绝时间被定义为灭绝风险的度量，其中物种在未来的持续性的现值呈指数下降。下降率必须大大低于经济贴现率，以实现代际可持续性。贴现平均灭绝时间的倒数和对数的增加被认为是灭绝风险的度量。我们将这些措施应用于将于2005年举行的日本世界博览会的环境影响评估。开发将对受威胁的鼠尾草物种产生更大的影响，而不是对星星木兰，木兰毛白杨，这已被保护的改变网站计划。(C)2003 Elsevier Ltd.保留所有权利。
The Red Data Book of Japanese Vascular Plants is based on their risk of extinction. In order to construct the list, 2000 taxa were evaluated using population data and rates of decline for approximate to4400 grids, each of approximate to100 km(2). This database can be used to estimate the impact of human activity on a threatened plant's risk of extinction. In order to evaluate extinction risks and apply the evaluation to conservation actions, the discount mean time to extinction is defined as a measure of extinction risk, where the present value of a species' persistence in the future decreases exponentially. The rate of decrease has to be much less than the rate of economic discounting, in order to realize intergenerational sustainability. Increases of the inverse, and logarithm, of the discount mean time to extinction are considered measures of the extinction risk. We applied these measures to an environmental impact assessment for the Japanese World Exposition that is to be held in 2005. Development will have a greater impact on threatened Salvia species than it will on star magnolia, Magnolia tomentosa, which has been conserved by changing the site plan. (C) 2003 Elsevier Ltd.
