摘要

2022年联合国气候变化大会(COP27)重申,最迫切需要采取行动,加快恢复政策,到2030年遏制和扭转自然生态系统的丧失,到2050年实现生态系统的全面恢复。土地占用是一个重要的排放源,并导致全球变暖和自然生态系统中生物多样性的丧失。因此,通过定量和正式地调查这一现象来采取行动是至关重要的,从而有助于实现零净土地占用的目标。近年来,世界范围内的土地占用变得巨大,在某些情况下导致形成紧凑、高密度的城市住区。在其他情况下,它导致了分散的、低密度的城市定居点。本研究的基本假设是紧凑的环境比分散的城市环境更具可持续性(环境、经济和社会)。因此,本研究旨在从城市住区模式及其在意大利领土上的分散的角度来调查土地的演变。通过对全球Moran指数和其他定量变量的时空分析,分析了意大利人聚落在区域和省级层面的空间格局。结果为每个地区提供了从50年代到现在的主要扩张动态:紧凑城市,城市蔓延或城市零星分布。

Urban dispersion indicator to assess the Italian settlement pattern
The 2022 United Nations Climate Change Conference (COP27) reaffirmed the most urgent need to build actions to accelerate the restoration of policies to arrest and reverse the loss of natural ecosystems by 2030 and move towards full ecosystem recovery by 2050. Land take is a significant source of emissions and contributes to global warming and biodiversity loss in natural ecosystems. Consequently, it is crucial to act on it by investigating the phenomenon quantitatively and formally, thus contributing to the goal of zero net land take. In recent years, land take worldwide has become massive, leading in some cases to forming compact, high-density urban settlements. In other cases, it has led to dispersed, low-density urban settlements. The basic assumption underlying this research is that a compact context is more sustainable (environmentally, economically, and socially) than a dispersed urban one. Consequently, this research aims to investigate the evolution of land take from the point of view of the pattern of urban settlements and their dispersion over the Italian territory. The spatial configuration of the Italian settlement pattern at the regional and provincial level was analyzed through a Spatio-temporal analysis of the global Moran index and other quantitative variables. The results provide, for each territory, a reading of the main expansion dynamics that occurred from the ‘50s to nowadays: compact city, urban sprawl, or urban sprinkling.
