城市化正在改变生态系统服务的使用，特别是在亚洲、非洲和南美洲以前偏远的山区，现在更容易到达。环境服务使用的变化在整个社会并不一致，但受到收入等社会经济因素的影响。我们试图了解ES使用的变化沿着梯度的城市化，以及相关的收入差异沿着这一梯度。我们的研究是在Spiti山谷进行的，Spiti山谷以前是印度喜马拉雅山脉的一个偏远地区，正在经历城市化。我们采用家庭调查和货币估值来评估当地（野生植物，粪便，木材，饲料，水，肥料，大麦）和进口（木柴和肥料）供应服务的使用。我们使用ANOVA和ANCOVA来检验ES使用与城市化和收入的差异。我们发现，随着城市化的发展，当地供应服务的使用减少，而进口供应服务的使用增加。在农村地区，使用当地供应服务的情况不随收入的增加而改变，而在小城市中心，则随收入的增加而增加。在各种结算类型中，进口ES的使用随着收入的增加而增加。我们的研究结果强调了ES使用如何随着相对少量的城市化而变化。它们还表明，不仅需要使农村人口，而且也需要使城市人口能够获得当地供应服务。
Urbanization is changing the use of ecosystem services, especially in previously remote mountain areas in Asia, Africa, and South America that are now more accessible. Change in ES use is not uniform across society, but is impacted by socio-economic factors like income. We sought to understand changes in ES use along a gradient of urbanization, and as related to income differences along this gradient. Our study was conducted in Spiti Valley, a formerly remote region in the Indian trans-Himalayas that is undergoing urbanization. We employed household surveys and monetary valuation to assess use of local (wild plants, dung, wood, forage, water, fertilizer, barley) and imported (firewood and fertilizers) provisioning services. We used ANOVAs and ANCOVAs to test for differences in ES use with urbanization and income. We found that the use of local provisioning services decreased with urbanization, while that of imported provisioning services increased. In rural spaces, the use of local provisioning services did not change with income, while in small urban centres it increased with income. Across settlement types, imported ES use increased with income. Our findings highlight how ES use can change with relatively small amounts of urbanization. They also indicate that local provisioning services need to be made accessible not only to rural populations but also to those in relatively more urban areas.
