Carbon Security Management (2020)

<p>We created an index to look at carbon security in the sagebrush steppe across the Great Basin. Our index uses a fractional plant cover dataset from the Rangeland Analysis Platform (https://rangelands.app/), a fire probability model dataset created for the Great Basin (Smith et al., 2023), and the resistance and resilience categorical dataset created for the sagebrush steppe (Chambers et al., 2014, 2017). Our carbon security index (CSI) is made up of three parts as following: CSI = Preferred Rangeland Cover Index + Resistance &amp; Resilience – P(Fire) The result is an index that spans from -2 to +2 and can be used to compare carbon security in different spatial.

我们构建了一项指标，用于评估大盆地（Great Basin）范围内艾灌丛草原（sagebrush steppe）的碳安全水平。本指标依托三类数据集构建：其一为来自牧场分析平台（Rangeland Analysis Platform，https://rangelands.app/）的植被盖度分数数据集；其二为针对大盆地开发的火灾概率模型数据集（Smith等，2023）；其三为针对艾灌丛草原开发的抗性与恢复力分类数据集（Chambers等，2014、2017）。本研究中的碳安全指数（Carbon Security Index，CSI）由三部分构成，具体计算公式如下：CSI = 优先牧场覆盖指数 + 抗性与恢复力分值 – 火灾发生概率（P(Fire)）。该指数的取值范围为-2至+2，可用于对比不同空间区域的碳安全水平。如需了解方法细节与理论依据，请参阅相关研究论文。
