Before evaluating the abundance and quality of nature in a city, one must define the concept of nature according to resident experience and climatological conditions. For Los Angeles (L.A.) County, home to a sociologically diverse and highly developed city in a Mediterranean climate that experienced drought conditions for the last decade, this represents a formidable theoretical and empirical challenge. In support of an Integrated Vulnerability Assessment, we developed an index of natural resources with the aid of local partnerships. This effort required local expert participation and resulted in the creation of a large database of available regional data. This index was created to investigate the spatial footprint of natural resources in relation to predicted high risk natural hazard areas. This paper demonstrates analytical applications of this index, which consists of six component indicators: greenness, biodiversity, habitat fragmentation, significant ecological areas, tree canopy cover, and wetland cover. Data for each component were compiled into a geodatabase, scaled, aggregated to Census block group areas, and combined to create the natural resources index (the Index). The Index can then be compared with natural hazard spatial data to determine relative vulnerability to these hazards, interactions with other types of vulnerabilities, and where adaptive capacity may be lacking. Results highlight areas of opportunity for multifaceted risk mitigation and adaptation efforts.

在高度城市化和干旱的洛杉矶乡村创建基于生态系统服务的定量自然指数

在评估城市中自然的丰度和质量之前,必须根据居民的经验和气候条件定义自然的概念。对于洛杉矶(LA)县来说,这里是一个社会学多样且高度发达的城市,在地中海气候中居住,过去十年经历了干旱条件,这代表了巨大的理论和经验挑战。为了支持综合漏洞评估,我们在地方合作伙伴的帮助下制定了自然资源指数。这项工作需要当地专家的参与,并导致建立了一个庞大的可用区域数据数据库。创建该指数的目的是调查与预测的高风险自然灾害区域有关的自然资源的空间足迹。本文展示了该指数的分析应用,该指数包括六个组成指标:绿色度,生物多样性,生境破碎化,重要的生态区域,树冠覆盖和湿地覆盖。将每个组件的数据编译到地理数据库中,进行缩放,汇总到人口普查区块组区域,然后合并以创建自然资源索引(索引)。然后可以将该指数与自然灾害空间数据进行比较,以确定对这些灾害的相对脆弱性,与其他类型脆弱性的相互作用以及可能缺乏适应能力的地方。结果突出显示了进行多方面风险缓解和适应工作的机会领域。和湿地覆盖。将每个组件的数据编译到地理数据库中,进行缩放,汇总到人口普查区块组区域,然后合并以创建自然资源索引(索引)。然后可以将该指数与自然灾害空间数据进行比较,以确定对这些灾害的相对脆弱性,与其他类型脆弱性的相互作用以及可能缺乏适应能力的地方。结果突出显示了进行多方面风险缓解和适应工作的机会领域。和湿地覆盖。将每个组件的数据编译到地理数据库中,进行缩放,汇总到人口普查区块组区域,然后合并以创建自然资源索引(索引)。然后可以将该指数与自然灾害空间数据进行比较,以确定对这些灾害的相对脆弱性,与其他类型脆弱性的相互作用以及可能缺乏适应能力的地方。结果突出显示了进行多方面风险缓解和适应工作的机会领域。以及可能缺乏适应能力的地方。结果突出显示了进行多方面风险缓解和适应工作的机会领域。以及可能缺乏适应能力的地方。结果突出显示了进行多方面风险缓解和适应工作的机会领域。
