Non-Urbanised Areas (NUAs) are part of agricultural and green infrastructures that provide ecosystem services. Their role is fundamental for the minimization of urban pollution and adaptation to climate change. Like all natural ecosystems, NUAs are endangered by urban sprawl. The regulation of sprawl is a key issue for land-use planning. We propose a land use suitability strategy model to orient Land Uses of NUAs, based on integration of Land Cover Analysis (LCA) and Fragmentation Analysis (FA). With LCA the percentage of evapotranspiring surface is defined for each land use. Dimensions and densities of NUAs patches are assessed in FA. The model has been developed with Geographical Information Systems, using an extensive set of geodatabases, including orthophotos, vectorial cartographies and field surveys. The case of the municipality of Mascalucia in Catania metropolitan area (Italy), characterized by a considerable urban sprawl, is presented.
非城市化区域（NUAs）是农业和绿色基础设施的一部分，提供生态系统服务。它们在最小化城市污染和适应气候变化方面发挥着重要作用。与所有自然生态系统一样，NUAs 也受到城市扩张的威胁。因此，对城市扩张的监管是土地利用规划的关键问题。我们提出了一种土地利用适宜性策略模型，该模型基于土地覆盖分析（LCA）和破碎化分析（FA）的综合，用于指导 NUAs 的土地利用。通过 LCA 可以确定每种土地利用的蒸散表面百分比。在 FA 中评估 NUAs 斑块的维度和密度。该模型是使用地理信息系统开发的，使用了大量的地理数据库，包括正射影像、矢量制图和实地调查。以意大利卡塔尼亚大都市区马斯卡卢西亚市为例，该地区存在大量的城市扩张。
