Urban soils exhibit a wide diversity of properties that have no equivalent in other environments but are overwhelmingly perceived as degraded by decision makers. As a result, their potential is not considered in urban planning even though they can deliver a range of ecosystem services. This paper describes a decision support tool for assessing soil ecosystem services to support urban land use planning. An overview of existing methods for assessing ecosystem services provided by urban soils has been detailed. Destisol, a model developed specifically for the urban context, is presented in detail. Destisol was then applied to 37 urban soils under various situations and pedoclimates. The main innovations of Destisol lie in the consideration of soil properties throughout the whole pedon and in the evaluation of the compatibility of the soil with different land covers. It is based on the acquisition of soil indicators, which are transformed into scores of soil functions, then into compatible land covers and finally into scores of ecosystem services. The architecture of the model is based on 20 physico‐chemical‐biological soil indicators used to score 15 soil functions, based on a detailed set of decision rules. The soil functions scores allow the calculation of a percentage of compatibility for 13 land covers. Finally, the resulting scores are used to evaluate 18 ecosystem services, as a function of land cover. The tests show a wide distribution of scores depending on the soil studied, but also depending on the soil function, land cover or ecosystem service considered. Technosols show the largest dispersion of soil function scores, and no correlation was found between the anthropization gradient and the mean soil function score. The main results of Destisol are an assessment of the soil suitability, that is the compatibility between a soil and a land cover, and an explicit assessment of the ecosystem services provided depending on the land covers.

Destisol：一种决策支持工具，用于评估城市土壤提供的生态系统服务，以实现更好的城市规划


城市土壤表现出多种特性，这些特性在其他环境中没有，但绝大多数决策者认为这些土壤已经退化。因此，即使它们可以提供一系列生态系统服务，它们的潜力也不会在城市规划中得到考虑。本文介绍了一种决策支持工具，用于评估土壤生态系统服务以支持城市土地利用规划。详细介绍了评估城市土壤提供的生态系统服务的现有方法。详细介绍了 Destisol，一种专为城市环境开发的模型。然后将 Destisol 应用于不同情况和土壤气候下的 37 种城市土壤。Destisol 的主要创新在于考虑整个土壤的土壤特性，并评估土壤与不同土地覆盖的相容性。它基于土壤指标的获取，这些指标被转化为数十种土壤功能，然后转化为兼容的土地覆盖，最后转化为数十种生态系统服务。该模型的架构基于 20 个物理-化学-生物土壤指标，这些指标用于根据一组详细的决策规则对 15 个土壤功能进行评分。土壤函数分数允许计算 13 个土地覆被的兼容性百分比。最后，所得分数用于评估 18 种生态系统服务，作为土地覆盖的函数。测试显示，根据所研究的土壤，但也取决于所考虑的土壤功能、土地覆盖或生态系统服务，分数分布广泛。Technosols 显示土壤功能评分的离散度最大，并且人类化梯度与平均土壤功能评分之间没有发现相关性。 Destisol 的主要结果是对土壤适宜性的评估，即土壤和土地覆盖之间的相容性，以及根据土地覆盖提供的生态系统服务的明确评估。
