摘要

全球气候变化和人为干扰严重影响了干旱地区的可持续发展,而协调城市与水的关系(CWR)是干旱地区可持续发展的基础。塔里木河流域(TRB)是中国西北地区最大的旱地,面临着严峻的可持续发展挑战;然而,由于文献和记录稀少,人们对其长期的城市水关系知之甚少。本研究利用历史遗址重建城市数据,并确定塔里木河流域城市水系统在过去 2000 年中的演变情况。研究提出了旱地驱动机制框架,以解释城市水系演变机制。研究结果表明:1)城市在 "沙漠-平原-山地 "的连续过程中呈现出 "由外而内 "的运动趋势;城市首先在沙漠中部附近殖民,随后向周围平原撤退,再向外围山地撤退,最后返回平原。2) 城市数量与河流长度的总体相关系数为 0.734(P 值为 0.001),且随时间变化而波动。3)此外,气候变化、水利工程、人口和耕地增长以及战争也对演变过程产生了重大影响。TRB 的经验和方法有助于分析类似地区的城市与水的关系,促进全球旱地的可持续发展。

Colonize the desert vs. retreat to the mountains: The evolution of city-water relationships in the Tarim river basin over the past 2000 years

Global climate change and anthropogenic disturbances have seriously affected sustainable development in drylands, where coordinated city-water relationships (CWRs) are foundational. The largest dryland in Northwest China, the Tarim River Basin (TRB) faces severe sustainability challenges; however, its long-term CWRs are poorly understood due to the scarcity of literature and records. This study utilized historical ruin sites to reconstruct city data and determine the evolution of the TRB city-water system over the past 2000 years. A driving mechanism framework for drylands was proposed to explain the CWR evolution mechanisms. The results revealed that 1) the cities exhibited an “outward-inward” movement trend in the “desert-plain-mountain” continuum; they first colonized near the central desert, subsequently retreated to the surrounding plains and then to the peripheral mountains, and finally returned to the plains. 2) The overall correlation coefficient between the number of cities and the length of rivers was 0.734 (p value < 0.001), which fluctuated over time. 3) Furthermore, climate change, water conservancy projects, population and arable land growth and wars exerted significant effects on the evolutionary process. The TRB's experiences and methods could help analyze city-water relationships in similar regions and promote sustainable development of drylands worldwide.

期刊介绍: Applied Geography is a journal devoted to the publication of research which utilizes geographic approaches (human, physical, nature-society and GIScience) to resolve human problems that have a spatial dimension. These problems may be related to the assessment, management and allocation of the world physical and/or human resources. The underlying rationale of the journal is that only through a clear understanding of the relevant societal, physical, and coupled natural-humans systems can we resolve such problems. Papers are invited on any theme involving the application of geographical theory and methodology in the resolution of human problems.
