Allotment gardens (AGs), one of the basic types of urban gardening, provide goods and services as recreation and climate regulation to the urban population beyond food supply. Ecosystem services (ES) associated with these spaces and spatial factors, such as distances and the presence of substitutes, are of great importance. These aspects, previously studied in the literature, are rarely focused on the economic valuation, through which benefits are revealed. This paper evaluates the creation of AGs in a peri-urban degraded agroecosystem in Murcia (SE-Spain). The values of ES are quantified economically, so are the influences of the socioeconomic and spatial characteristics. A survey was undertaken, from which the willingness to pay (WTP) for owning an AG and the factors influencing the valuation were determined. The results indicate that provisioning services are the ES valued most highly. The valuation of the project for the whole population is 5.4 €/household/month, with a WTP of 17.2 €/household/month for owning an AG plot. Multivariate analysis showed the importance of ES and spatial factors in this valuation. This WTP spatial study shows the existence of local patterns to be considered in the evaluation of new AGs location alternatives. These results will be useful to urban planners in their decision making.

郊区退化的农业生态系统中分配花园的经济价值:公民偏好在空间规划中的作用

分配花园(AGs)是城市园艺的基本类型之一,除了提供食物外,还为城市居民提供娱乐和气候调节等商品和服务。与这些空间和空间因素(例如距离和替代物的存在)相关的生态系统服务(ES)非常重要。以前在文献中研究过的这些方面很少集中在经济价值上,而通过经济价值来揭示收益。本文评估了穆尔西亚(西班牙)城市郊区退化的农业生态系统中AG的产生。ES的值在经济上可以量化,社会经济和空间特征的影响也可以量化。进行了一项调查,从中确定了拥有股份公司的支付意愿(WTP)和影响估值的因素。结果表明,预配服务是价值最高的ES。该项目对整个人口的估值为5.4欧元/户/月,拥有AG地块的WTP为17.2欧元/户/月。多变量分析显示了ES和空间因素在此评估中的重要性。这项WTP空间研究表明,在评估新的AG位置替代方案时要考虑本地模式的存在。这些结果将对城市规划者的决策有用。这项WTP空间研究表明,在评估新的AG位置替代方案时要考虑本地模式的存在。这些结果将对城市规划者的决策有用。这项WTP空间研究表明,在评估新的AG位置替代方案时要考虑本地模式的存在。这些结果将对城市规划者的决策有用。
