coupling Relationship between Transport Superiority degree and Urbanization in Sichuan,China

Relationship between transport superiority degree and urbanization is not quantified enough in recent researches.Combined with coupling model and coupling coordination model,the spatial analysis technique was applied to quantitatively analyzing the relationship between transport superiority degree and comprehensive urbanization in eighteen prefecture-level cities in Sichuan from 2000 to 2011. An evaluation index system was constructed,and index weights were obtained using the variation coefficient method. The traffic volume was found to be the main factor contributing to transport superiority degree, and space urbanization was the primary factor influencing comprehensive urbanization. The coupling degree between transport superiority degree and urbanization( CU) was generally higher than the coupling coordination degree( DU) in 2000-2011. DUvaried more significantly than CU. In 2011, Sichuan was divided into five regional types. Based on the above observations, targeted recommendations were developed.

Quantifying the spatiotemporal characteristics of ecosystem services and livelihoods in China’s poverty-stricken counties

Understanding the coupling relationship between ecosystem services and poverty livelihoods is a prerequisite for poverty eradication and ecological protection in China.In this paper,we intended to quantify the coupling relationship between ecosystem services and poverty livelihoods in 717 poverty-stricken counties in China.First,we identified distinct levels of ecosystem services and poverty respectively in the poverty-stricken areas based on the ecosystem services subsystem index and poverty livelihoods subsystem index.Then,we calculated the coupling degree and coupling coordination degree between the ecosystem services and the poverty livelihoods in China^poverty-stricken counties from 2000 to 2015.Finally,we analyzed the temporal and spatial evolution of the coupling between ecosystem services and poverty livelihoods.The results indicate that the ecosystem services showed a trend of first decreasing and then increasing,while the poverty level showed an increased trend.In addition,the coupling relationship between ecosystem services and poverty livelihoods in poverty-stricken counties was also improved from 2000 to 2015.However,the coupling degree value or coupling coordination degree values in some counties or contiguous impoverished areas showed a decreased trend,the coupling relationship between ecosystem services and poverty livelihoods in those counties or areas was higher conflict.Future more,the coupling relationship in China's poverty-stricken counties was mainly intermediate conflict and low conflict,which need to improve in the future.Thus,it is suggested that effective measures are required to lift ecosystem services out of the poverty trap and into sustainable livelihoods.

Interactions between water-land resources and oasis urban development at the northern slopes of the Tianshan Mountains,Xinjiang,China

Journal of Arid Land 2012年第2期4卷 221-229页

Urban development in arid and semi-arid regions is largely constrained by fragile physical environ- ments. The characteristics of an urban settlement are different from those in other regions of China. This paper analyses the coupling characteristics and spatio-temporal variations for oasis urban development and water-land resources at the northern slopes of the Tianshan Mountains by principal component analysis and a coupling degree model. The result shows that the degree and change in regional use of water and land resources are different among the studied cities/counties during their development. The built-up areas of these cities/counties have changed little with increasing populations and urbanization levels, which well reflects that the urban development in arid and semi-arid regions is limited by oasis areas. Per capita amount of water supplied, however, presented a trend of slowed growth with increasing levels of urbanization. Water consumption gradually increased with urban development and the improvement of people＇s living standards, accompanied by enhanced water use efficiency. The level of urbanization can be assessed through the coupling degree between oasis urban development and the use of water and land resources. A high coupling degree represents a high level of comprehensive urban devel- opment and use of water-land resources. Alternatively, a low coupling degree denotes a low level of urban devel- opment and water-land resource use.

A Study on the coupling Relationship between Low Carbon Economy and Environmental Resources in Jilin Province

引用

Journal of Landscape Research 2021年第4期13卷 62-66页

作者： GAO Hewen Changchun Humanities and Sciences Collage ChangchunJilin 130117China

In Jilin Province,China,economic development,high output and rational use of resources have become a pair of unrelieved contradictions.The coupling of eco-environmental and socioeconomic systems is not a simple linear addition of these two systems to form an advanced composite system.Therefore,the analysis of the coupling degree between ecological environment and socioeconomic system from the perspective of dissociative structure can be expressed through the establishment of a system coupling model to express the relationship between the two systems.On this basis,a series of analytical indicators are constructed to quantitatively evaluate and qualitatively analyse the coupling between ecological environment and socioeconomy.

在对城镇化驱动因素的相关研究进行回顾和灰色关联分析基础上，从经济系统的视角构建了中国城镇化驱动机制的理论模型，建立了省区城镇化核心驱动力计量模型。实证结果表明：城镇化与经济发展水平逐步协调；服务业的驱动作用已超过第二产业，但工业仍是中西部省区城镇化的核心驱动力；乡村工业化短期内对城镇化有延滞作用，但对城镇化的平稳推进和大中小城市协调发展具有长期效应；笔者更倾向于用内生的观点看待中国城镇化。文章建立了基于驱动力演变的城镇化四阶段模型，并提出应以科学的区域定位为基础培育区域城镇化的核心驱动力。
