Construction Strategies of Social Security System for Wan-jiang Urban Belt's Migrant Workers

Theoretical debate and practice exploration on social security of migrant workers were introduced.The political direction and security layer on social security for migrant workers in Wan-jiang urban belt were analyzed:the first layer is to implement wage payment guarantee and employment injury insurance;the second layer is to emphasize serious disease insurance and endowment insurance;the third layer is unemployed insurance and social assistance.The primary strategy of building a social security system for migrant workers in Wan-jiang urban belt was put up:wage payment guarantee system that is united in certain regions should be promoted;employment injury insurance system that is undertaken by enterprises should be built;a social health care system for serious diseases should be set up;multi-layers endowment insurance system for migrant workers should be created;vocational training and training in how to start a business should be built as well as the unemployment insurance system;social assistant system based on the basic cost of living allowances should be set up.

Spatio-temporal evolution and factor explanatory power analysis of urban resilience in the Yangtze River Economic Belt

Urban resilience assesses a city’s ability to withstand unknown risks.Scholars are not comprehensive in assessing urban resilience,and they lack consideration of population resilience.This study investigated 110 prefecturelevel cities in the Yangtze River Economic Belt(YREB)as study areas.We calculated the YREB’s level of urban resilience based on the aspects of“economy-society-population-ecology-infrastructure”,which ensured that the comprehensive evaluation of urban resilience is complete and sufficient.The spatio-temporal evolution of urban resilience was analyzed using exploratory spatial data.Geodetectors were used to investigate the impact of several indicators,focusing on economic,social,population,ecological,and infrastructure factors,on urban resilience.The results showed that the urban resilience of the YREB has maintained a slow upward trend from 2005 to 2018,and the average urban resilience of the YREB has risen from 0.2442 to 0.2560.The resilience gap between cities in the study region increased initially and then decreased.The dominant factor in the spatial differentiation of urban resilience was the economic factors,followed by the population factors.Urban resilience has been clarified and an evaluation index system is constructed,which can provide an effective reference for the evaluation of urban resilience among countries around the world.Based on this,factors that optimize urban resilience are configured,and the regional and national sustainable development can be promoted.

数字经济与新型城镇化的耦合协调关系及空间效应——以长江经济带为例

文章以长江经济带11个省份为研究对象,构建数字经济发展指数和新型城镇化指数指标体系,利用熵权-TOPSIS法、耦合协调度模型、空间杜宾模型等,对长江经济带两系统耦合协调关系及空间效应进行分析。结果表明:长江经济带两系统为“新型城镇化建设主导、数字经济发展滞后”发展模式,数字经济发展与新型城镇化建设均面临突出的不平衡问题,极化现象较为明显。两系统的耦合协调状态由轻度失调状态发展为勉强协调状态,在空间上呈现“下游>中游>上游”的发展格局,且具有显著的空间相关性。增强技术创新能力、优化产业结构、完善交通基础设施、提高对外开放水平和提升政府能力对两系统耦合协调发展具有显著的正向驱动作用。其中,优化产业结构、完善交通基础设施和提高对外开放水平会对邻近地区的两系统耦合协调发展产生正向空间溢出效应。

基于GTWR模型的长江经济带城市群减污降碳及其影响因素分析

以长江经济带三大城市群71个城市为研究对象,使用耦合协调度模型测度2011—2020年三大城市群减污降碳协调度,使用时空地理加权回归(GTWR)模型探究各城市群减污降碳影响因素的时空异质性。结果表明,研究期内长江经济带三大城市群减污降碳协调度整体呈上升趋势,截至2020年,三大城市群减污降碳均达到协调状态,其协调度由高到低依次为成渝城市群、长江中游城市群、长三角城市群;影响因素回归结果显示,城镇化、科技创新和环境规制能够促进减污降碳协同,人口集聚、产业结构则会抑制减污降碳,而经济发展水平、对外开放在三大城市群间表现出明显的时空异质性。基于此,从经济发展、社会进步、科技创新以及政策规制层面提出差异化的减污降碳协同治理策略,助力各城市群乃至长江经济带减污降碳目标的实现。

Impact of economic development on wetlands in Hangzhou Bay Industrial Belt

Based on Landsat TM images in 2005 and urban planning data of 2005-2020 in Hangzhou Bay Industrial Belt, this paper studied the potential risk of the planned urban construction land extension to the wetlands by employing a GIS spatial analysis method. The results show that： （1） The wetland resources are widely distributed and diverse, with a proximal distribution to present urban construction lands spatially. （2） From 2005 to 2020, the urban construction lands will expand vastly and rapidly, and will take over large areas of wetlands that are mostly the ponds and the aquiculture water areas in the reclamation areas of Hangzhou Bay south coast. Moreover, this change will be spatially uneven obviously, e.g., the most serious recessions of the wetlands are concentrated in Ningbo city, Hangzhou city and Cixi city. （3） Overall, the potential risk to wetlands is very high, and will keep increasing with the trend of urbanization. （4） The quantity and spatial pattern of the planning urban construction land have substantial impacts on the wetland loss. Therefore, some policies and regulations are suggested to coordinate the relationship between urban economic development and wetland resource protection such as adjusting the construction land planning, compensating for wetland occupation as well as constructing wetland parks.

Response of ecosystem service value to land use/cover change in the northern slope economic belt of the Tianshan Mountains, Xinjiang, China

Land use/cover change(LUCC)is becoming more and more frequent and extensive as a result of human activities,and is expected to have a major impact on human welfare by altering ecosystem service value(ESV).In this study,we utilized remote sensing images and statistical data to explore the spatial-temporal changes of land use/cover types and ESV in the northern slope economic belt of the Tianshan Mountains in Xinjiang Uygur Autonomous Region,China from 1975 to 2018.During the study period,LUCC in the study region varied significantly.Except grassland and unused land,all the other land use/cover types(cultivated land,forestland,waterbody,and construction land)increased in areas.From 1975 to 2018,the spatial-temporal variations in ESV were also pronounced.The total ESV decreased by 4.00×10^(8) CNY,which was primarily due to the reductions in the areas of grassland and unused land.Waterbody had a much higher ESV than the other land use/cover types.Ultimately,understanding the impact of LUCC on ESV and the interactions among ESV of different land use/cover types will help improve existing land use policies and provide scientific basis for developing new conservation strategies for ecologically fragile areas.

This paper analyzed landscapes of urban riverfront environment, embankment landscape engineering, and waterfront plant cultivation, so as to further explore landscape construction of urban waterfront environment.

The Coupling of Landscape Pattern and Landscape Esthetics of Urban Traditional Cultural Tourism Destination: A Case Study of Confucius Temple-Qinhuai River Scenic Area in Nanjing City

Study on the relationship between landscape beauty and ecological beauty is an important scientifi c problem that refl ects the nature of man-land relation, and current academic researches on this topic are most based on a single perspective. Therefore, this paper took the Confucius Temple–Qinhuai River Scenic Area in Nanjing City as a typical case of urban traditional cultural tourism destination, adopted landscape pattern indexes and balanced incomplete block comparison and evaluation method as the evaluation standards of ecological beauty and landscape beauty, and analyzed the coupling characteristics and rules of landscape pattern and landscape aesthetics. The results showed that(a) The overall landscape of the study area had higher fragmentation degree, but different landscape groups were infl uenced by different human interventions, landscape patches showed moderate diversity and heterogeneity, patch area, spatial distribution and spatial aggregation degree showed structural differences.(b) The locals and visitors had aesthetic perception of the study area, but preferred the beautiful natural scenery of the Qinhuai River, as well as the historical buildings and cultural landscapes that contain rich memories of the city.(c) Landscape pattern and landscape aesthetics showed coupled complementation and harmonious coexistence. The Confucius Temple–Qinhuai River Scenic Area has profound historical and cultural background, but it has witnessed gradual loss of cultural characteristics and fast "delocalization" against the background of rapid urbanization. As an urban traditional cultural tourism destination, it carries the responsibility of protecting city memories and inheriting regional cultures.
