“城市等级体系”指什么？
What does the “urban hierarchy” refer to?
城市等级体系指区域内城市按人口规模、经济功能和辐射范围呈金字塔分布：少数大城市居顶，众多小城镇居底。中心地理论解释了为何每级城市服务半径与数量有规律。它帮助理解资源与人口的宏观布局。
The urban hierarchy describes cities in a region arranged like a pyramid by population, economic function, and sphere of influence: a few large cities at the top, many small towns at the bottom. Central-place theory explains why each level's service radius and number follow patterns. It helps understand the macro layout of resources and population.

什么是“城市群”？
What is a “city cluster”?
城市群是若干相邻、经济联系紧密并共享基础设施的城市组成的集合体，如长三角、珠三角。它突破单一城市边界，形成分工协作的区域网络。城市群已成为国家参与全球竞争的重要空间单元。
A city cluster is a group of neighboring cities with close economic ties and shared infrastructure, such as the Yangtze Delta or Pearl River Delta. It breaks single-city boundaries to form a regionally networked division of labor. City clusters have become key spatial units for national competition globally.

霍华德的“花园城市”理念想解决什么？
What did Howard's “garden city” idea aim to solve?
19世纪末霍华德提出花园城市：在限制规模的小城中平衡住宅、工厂与农田，用绿带分隔，避免伦敦式的拥挤与污染。它影响了现代卫星城与新城规划。核心是用规划兼顾效率与生活品质。
At the end of the 19th century Howard proposed the garden city: small towns of limited size balancing homes, factories, and farmland, separated by green belts to avoid London-style crowding and pollution. It influenced modern satellite and new-town planning. Its core was using planning to balance efficiency and quality of life.

工业革命为什么让城市快速膨胀？
Why did the Industrial Revolution make cities swell rapidly?
工厂集中建在城市周边，需要大量劳动力，农民离开土地进城务工，城市人口短期内激增。铁路与蒸汽动力又强化了城市的集聚效应。这造成了住房拥挤、卫生恶化等早期“城市病”。
Factories clustered around cities and needed large labor forces, so peasants left the land for urban work and city populations surged in a short time. Railways and steam power reinforced the agglomeration effect of cities. This produced early “urban diseases” like crowded housing and poor sanitation.

“城中村”是怎么形成的？
How do “urban villages” form?
城中村是城市扩张吞并原有村庄后，土地被包围却仍保留集体户籍与自建低层住宅的区域。因租金低廉，它们成为外来务工者的主要落脚点。它反映了快速城市化中规划与现实的错位。
Urban villages are former villages engulfed by city expansion, where land is enclosed but collective household registration and self-built low-rise housing remain. Because rents are low, they become main foothold for migrant workers. They reflect the mismatch between planning and reality in rapid urbanization.

城市化早期为什么常伴随传染病流行？
Why did early urbanization often coincide with epidemics?
人口骤然密集、饮水与排污系统跟不上，使霍乱、鼠疫等传染病在城市中极易传播。19世纪欧洲城市就曾因卫生落后爆发多次瘟疫。现代下水道与公共卫生体系正是为应对这一问题而建。
Sudden population density with lagging water and sewage systems made cities ideal for spreading cholera, plague, and similar diseases. 19th-century European cities saw repeated outbreaks due to poor sanitation. Modern sewers and public health systems were built precisely to address this.

“紧凑城市”理念主张什么？
What does the “compact city” concept advocate?
紧凑城市主张高密度、混合用地和优先公共交通，以缩短出行距离、节约土地并减少碳排放。它反对无序蔓延，强调步行可达的生活圈。许多欧洲城市以此作为可持续发展方向。
The compact city advocates high density, mixed land use, and priority public transit to shorten travel, save land, and cut emissions. It opposes disorderly sprawl and emphasizes walkable living circles. Many European cities adopt it as a sustainable development direction.

为什么东京能容纳如此庞大的人口？
Why can Tokyo hold such a huge population?
东京都市圈依靠密集的轨道交通网、分层级的城市分工和高度集约的土地利用，把数千万人口高效组织起来。高效的通勤系统让远郊居民也能便捷进城工作。它是巨型城市管理的典型案例。
The Tokyo metropolis organizes tens of millions through a dense rail network, tiered urban division of labor, and highly intensive land use. An efficient commute lets far-suburban residents work in the city center easily. It is a classic case of managing a megacity.

“逆城市化”是什么意思？
What does “counter-urbanization” mean?
逆城市化指城市人口向郊区或小城镇回流，城市中心增长放缓甚至减少的现象。它常见于发达国家，因交通改善、中心城区成本高和生活偏好变化而出现。与城市化相反，它是城市扩散的下一阶段。
Counter-urbanization means population flowing back from cities to suburbs or small towns, with city-center growth slowing or even shrinking. It is common in developed countries, driven by better transport, high central-city costs, and changing lifestyle preferences. Opposite to urbanization, it is the next phase of city dispersal.

什么是贫民窟？
What is a slum?
贫民窟是城市中住房简陋、基础设施匮乏、人口密集的低收入聚居区，常出现在快速城市化而住房供给不足的地方。居民多从事非正式工作，缺乏稳定产权。改善贫民窟是全球城市发展的重要议题。
A slum is a low-income settlement in a city with crude housing, poor infrastructure, and high density, often appearing where rapid urbanization outpaces housing supply. Residents usually do informal work and lack secure property rights. Upgrading slums is a major issue in global urban development.

地铁最早出现在哪座城市？
In which city did the metro first appear?
世界上第一条地铁是1863年通车的伦敦大都会铁路，用蒸汽机车在地下运行以缓解地面拥堵。它开创了以轨道交通疏解城市交通的先河。如今地铁成为许多大都市的骨干公交。
The world's first metro was London's Metropolitan Railway, opened in 1863 with steam locomotives running underground to ease surface congestion. It pioneered using rail transit to relieve city traffic. Today the metro is the backbone of public transport in many metropolises.
