生物多样性生境质量模型(Habitat Risk Assessment, HRA)是InVEST模型套件中的一个重要组成部分,它用于评估生境的完整性和物种的生境风险。本案例将以全国生物多样性维持服务为例,详细说明HRA模型的实践操作过程,并列出相关公式。 步骤1:数据准备 在进行HRA模型操作之前,需要准备以下数据: 生境分布数据:包括不同物种的生...

To establish a relationship between impact risk and ecosystem service supply potential, while accounting for these two apparently conflicting assumptions, it has been proposed adding ecosystem services' abundance as a resilience descriptor to the habitat risk assessment (HRA) model from the InVEST tool,...

摘要:研究碳储量的时空分布格局,平衡土地开发利用与生态保护,促进城市低碳可持续发展,是中国“双碳战略”(碳排放稳定与自然碳吸收协调)的重要课题。然而,现有的研究很少关注不同空间政策下土地利用变化对省级生态系统碳储量的影响。在本研究中,我们建立了辽宁省碳密度数据库,并获得了过去20年碳储量的时空分布。然后,基...
