英文文献：Characterizing Spatial Pattern in Ecosystem Service Values when Distance Decay Doesn’t Apply: Choice Experiments and Local Indicators of Spatial Association-当距离衰减不适用时，生态系统服务价值的空间模式特征:空间关联的选择实验和局部指标

英文文献摘要：
Stated preference analyses commonly impose strong and unrealistic assumptions in response to spatial welfare heterogeneity. These include spatial homogeneity or continuous distance decay. Despite their ubiquity in the valuation literature, global assumptions such as these have been increasingly abandoned by non-economics disciplines in favor of approaches that allow for spatial patchiness. This paper develops parallel methods to evaluate local patchiness and hot spots in stated preference welfare estimates, characterizing relevant patterns overlooked by traditional approaches. The analysis draws from a choice experiment addressing river restoration. Results demonstrate shortcomings in standard treatments of spatial heterogeneity and insights available through alternative methods.
陈述的偏好分析通常强加强烈和不现实的假设来回应空间福利的异质性。这些包括空间同质性或连续距离衰减。尽管它们在估值文献中随处可见，但诸如此类的全球假设已被越来越多的非经济学科所抛弃，取而代之的是允许空间不完整的方法。本文开发了平行的方法来评估在陈述的偏好福利估计的地方补丁和热点，特征相关的模式被传统的方法忽略。本文的分析来自于对河流修复的选择实验。结果显示了空间异质性的标准处理和可通过其他方法获得的洞察力的缺陷。
