What happens to the land cover within the hinterland's altitudinal belts while Central Andean cities are undergoing globalization and urban restructuring? What conclusions can be drawn about changes in human land use? By incorporating a regional altitudinal zonation model, direct field observations and GIS analyses of remotely sensed long term data, the present study examines these questions using the example of Huancayo Metropolitano – an emerging Peruvian mountain city of 420,000 inhabitants, situated at 3260 m asl in the Mantaro Valley. The study's results indicate that rapid urban growth during the late 1980s and early 1990s was followed by the agricultural intensification and peri-urban condominization at the valley floor (quechua) – since the beginning of Peru's neoliberal era. Moreover, regarding the adjoining steep slopes (suni) and subsequent grassland ecosystems (puna), the research output presents land cover change trajectories that clearly show an expansion of human land use, such as reforestation for wood production and range burning for livestock grazing, even at high altitudes – despite rural–urban migration trends and contrary to several results of extra-Andean studies. Consequently, rural–urban planners and policy makers are challenged to focus on the manifold impacts of globalization on human land use – at all altitudinal belts of the Andean city's hinterland: toward sustainable mountain development that bridges the social and physical gaps – from the bottom up.

生机勃勃的山谷,苍白的山峰?秘鲁中部安第斯山脉的测压变化和城乡土地变化

当安第斯中部城市正在经历全球化和城市重组时,腹地海拔带内的土地覆盖会发生什么变化?关于人类土地利用的变化,可以得出什么结论?通过结合区域海拔分区模型、直接实地观察和遥感长期数据的 GIS 分析,本研究以万卡约大都会(Huancayo Metropolitano)为例来研究这些问题,这是一个新兴的秘鲁山城,拥有 420,000 名居民,位于海拔 3260 米处。曼塔罗谷。该研究的结果表明,自秘鲁新自由主义时代开始以来,在 1980 年代末和 1990 年代初的快速城市发展之后,谷底(克丘亚)的农业集约化和城郊共管化。而且,关于相邻的陡坡 (suni) 和随后的草原生态系统 (puna),研究成果展示了土地覆盖变化轨迹,清楚地显示了人类土地利用的扩大,例如重新造林用于木材生产和放牧放牧,即使在高海拔地区海拔高度——尽管有农村-城市迁移趋势,并且与安第斯以外地区的一些研究结果相反。因此,城乡规划者和政策制定者面临的挑战是要关注全球化对人类土地利用的多方面影响——在安第斯城市腹地的所有海拔带:实现可持续的山区发展,以自下而上地弥合社会和自然差距. 例如重新造林用于木材生产和放牧放牧,即使在高海拔地区也是如此——尽管有农村向城市迁移的趋势,并且与安第斯以外地区的一些研究结果相反。因此,城乡规划者和政策制定者面临的挑战是关注全球化对人类土地利用的多方面影响——在安第斯城市腹地的所有海拔带:实现可持续的山区发展,弥合社会和自然差距——自下而上. 例如重新造林用于木材生产和放牧放牧,即使在高海拔地区也是如此——尽管有农村向城市迁移的趋势,并且与安第斯以外地区的一些研究结果相反。因此,城乡规划者和政策制定者面临的挑战是要关注全球化对人类土地利用的多方面影响——在安第斯城市腹地的所有海拔带:实现可持续的山区发展,以自下而上地弥合社会和自然差距.
