Development of City Biodiversity Index

《生物多样性公约》第十届缔约方会议批准了城市生物多样性指数(新加坡指数，CBI)。然而，该指标有一些问题需要重新考虑，如每个城市的环境、适用性等。因此，我们从生物多样性、生态系统服务和治理的角度重新审视了评估方法，并将其应用于日本城市。此外，我们还成功致力于建立由日本国土交通省编制的日语版CBI(初版)。我们还揭示了改进评价方法的各种知识和方法，包括孤立森林植物的遗传多样性评价，以及利用密集机载激光雷达进行城市森林生境评价的方法。

The City Biodiversity Index (Singapore Index, CBI) is authorized at the COP 10 of the Convention on Biological Diversity. However, the index has issues to be reconsidered, such as the environment of each city, applicability etc. So, we re-examined the evaluation methods from the viewpoints of ‘biodiversity’, ‘ecosystem services’ and ‘governance’ to apply on Japanese cities. And, we successfully committed to establish a Japanese version of CBI (preliminary edition) compiled by the Ministry of Land, Infrastructure, Transport and Tourism of Japan. We also revealed the various knowledge and methods to improve the evaluation methods, including genetic diversity evaluation of plants in isolated forests, and urban forest habitat evaluation method using intensive airborne LiDAR.
