城市规模分布遵循“齐普夫定律”吗？
Does city-size distribution follow “Zipf’s law”?
齐普夫定律指出城市人口排序与规模近似成反比（第2大城市约为第1大的一半）。许多国家大致符合，反映集聚与迁移的均衡机制。
Zipf’s law: a city’s rank times its size is roughly constant (2nd city ≈ half the 1st). Many countries roughly fit it, reflecting equilibrium in agglomeration and migration.

城市更新中的“绅士化”如何导致 displacement？
How does “gentrification” cause displacement in urban renewal?
中产迁入改善老旧街区会推高房价与租金，原低收居民被迫迁出（绅士化），带来空间不平等与文化置换，需以可负担住房政策缓冲。
Inflow of middle-class residents upgrades old neighborhoods and raises housing costs, displacing low-income residents (gentrification), demanding affordable-housing policies.

Sprawl is low-density, car-dependent expansion raising commuting and energy use; compact cities use dense mixed-use land to improve transit efficiency and sustainability.

城市热岛效应会带来哪些健康与能源影响？
What health and energy impacts does the urban heat island have?
城市因混凝土、沥青吸热且绿地少，气温常高于周边郊区（热岛效应）。它加剧中暑与心脑血管风险、推高空调能耗，可通过增加绿地、反光屋顶与通风廊道缓解。
Cities are warmer than suburbs (the urban heat island) due to heat-absorbing surfaces and less greenery. It raises heat-illness and cooling energy use, mitigated by green space, reflective roofs, and ventilation corridors.
