城市周边地区是城市和农村活动并列的过渡区或相互作用区，景观特征受到人类活动的影响而迅速改变。这些土地覆盖变化的关键领域。导致水文、生态、地貌1和社会经济系统发生变化的问题往往被农村和城市管理部门所忽视。然而，随着城市的发展，它们的大部分增长都位于这些地区。随着城市的发展，许多城市周边的活动向外迁移;其他活动和土地使用与城市结构相结合。城市周边地区是临时的、新的居民和活动与长期土地使用的混合体，包括农场、村庄、采石场和森林斑块。城市周边地区有两股移民潮，造成了财富和社会地位的巨大差异：城市人寻求更简朴的生活方式或更便宜的住宿，而较贫穷的农村人则寻求工作和保健机会。许多城市的郊区拥有高价值的中产阶级财产和贫穷的移民棚户区，少数几个城市位于这些用途之间，这些用途将是商品园艺，砂和砾石工作和砖日坑，炼油厂，石油化工厂，发电站，制革厂，机场和出租车。城乡结合部在不同的群体中受到不同的评价。这些价值观因大陆、国家和地区而异。它们包括：
Peri-urban areas are the transition zone, or interaction zone, where urban and rural activities are juxtaposed, and landscape features are subject to rapid modifications, induced by human activities. These critical areas of land cover change. leading to uansformations in the hydrological, ecological, geomorphoIogica1 and socio-economic systems, are often neglected by both rural and urban administrations. However, as cities d e d o p , much of their growth is located in such areas. Many peri-urban activities move outwards as the c i~y grows; other activities and land uses become incorporated w i t h the urban 1 fabric. Peri-urban areas are mosaics of temporary, new residents and activities mingled with longstandmg land uses, incIuding farms, villages, quarries and / forest patches. Peri-urban areas receive two flows of migrants creating wide variations in wealth and social status: urban people seelung a more rurd lifestyle or cheawer accommodation, and poorer rurd people searching for woik and heher chances for their chrldren.
