Since 2001, the French and Chinese researchers have done a cooperative research on the comparison of integrated development of large fiver basins. The Yangtze River was chosen as a crux of this research and linked with other older river experiments like the Rhone, the Nile and the Mississippi. This research includes not only the environmental issues but also economic and social issues. One special issue journal has been published in French for our research results. Other two collective and comparative books in French and Chinese will be finished at the end of this year. In the future, the comparison should be widened to Italy (the Po), Egypt (the Nile development planning) and the United States (the Mississippi Basin) and we would like to enlarge our research group and want to link up different teams and research projects, in order to get a global understanding of large fiver regions phenomenon. 展开更多

Where the river is abundant, the trade and regional centres could be formed. However, along with the prosperity of the water-cities, massive urban construction and environmental issues are enormous challenges in human process. A “scientific” urban planning, “Sponge City”, “Resilient City”, regional and urban culture and characteristics get more and more attention. The theme of “water and city” is clearly of great historical value and practical significance for the new resilient urban and water management strategies. The paper will summarize characteristics of geographical, historical, socio-cultural and political realms in metropolitan deltas and the historical governance as well as the recent developments in the Yangtze River Delta. It will introduce urban development and water management in four water cities: the canal and the city-Yangzhou, the river and the city-Nanjing, the lake and the city-Suzhou and the sea and the city-Shanghai. And then it will analyze the inner motivation of the interaction between water and cities in Yangtze River Delta. Furthermore, learning from successful historical experiences, the paper will provide suggestions for future sustainable urban development. 展开更多

Coordinated development is a major concern in the construction strategy of the Yangtze River Economic Belt (YREB).However,there were few studies which have quantitatively measured the level of coordinated development in the YREB.This paper aimed to propose an comprehensive index system of coordinated development based on the theories of growth pole and complex ecosystem and new guidelines of development from the central government.The index system was composed by 18 indicators within 4 domains including economic development,technology & innovation,communication & transportation,and ecological protection.The scores of coordinated development capability of the 110 prefecture-level cities in the YREB were calculated and examined using natural break point analysis,spatial autocorrelation analysis and rank-size analysis.It was shown that Shanghai,Nanjing and Wuhan were leading the coordinated development in the YREB.Generally,the scores of coordinated development capability were higher in the eastern region of the YREB,in which the cities performed well in the domains of economic development,technology & innovation and communication & transportation yet showed poor performance in ecological protection.Most cities in the middle reaches of Yangtze river ranked in the middle in the YREB in all the domains,except the provincial capitals.The western region of the YREB got the lowest score in the coordinated development capability besides the largest cities such as Chongqing,Chengdu,Kunming and Guiyang.The correlation coefficients between ecological protection and other domains were very low,suggesting that few cities have achieved a win-win situation between environment protection and socio-economic development.We suggested 3 ways to promote coordinated development in the YREB:establish multi-level institutional designs;enhance the innovation in green industries;and strengthen the joint prevention and control of ecological risks. 展开更多

The Yangtze River Economic Belt is a key development project in China,and financial development is the core driving force for economic growth in the Yangtze River Economic Belt.At present,the financial development of the Yangtze River Economic Belt is not balanced,and there is an urgent need to quantify the differences in financial development.Drawing on the research of"maturity model"at home and abroad,from the two new perspectives of subjective and objective,the financial development difference is introduced into the maturity model as an organic whole,forming financial maturity and its indicator system,then taking the Yangtze River Economic Belt as the research object,the principal component analysis method is used to calculate the maturity.The results show that the financial development of the middle and lower reaches of the Yangtze River Economic Belt has obvious gradient differences both subjectively and objectively.The financial acceptance of the lower reaches of the Yangtze River and the total financial structure and structure are significantly higher than the middle and upper reaches,while financial efficiency is lower than the middle and upper reaches due to factors such as financial costs.Therefore,the financial development of the Yangtze River Economic Belt needs to improve the systematicness of finance,coordinate the growth of financial volume and structural adjustment,and improve the overall financial operation efficiency. 展开更多

In this paper, the effect of the mediation effect is mainly used to test and analyze the regression model, and most scholars have studied the impact of the modernization of the industrial structure on the income gap. However, this paper is from another perspective, based on the social background of high-quality development, the main study is the impact mechanism of urban and rural income gap on the industrial structure, taking the Yangtze River Delta as the main research object, and specifically selecting 22 central cities in the Yangtze River Delta region, which is also one of the highlights of this study. The regression model is constructed by using the intermediary effect, and the four intermediary variables of fiscal expenditure (M<sub>1</sub>), fixed asset investment (M<sub>2</sub>), number of patent applications (M<sub>3</sub>), and total import and export (M<sub>4</sub>) are selected, which represent the role of the government, fixed asset investment, scientific and technological level and opening-up level, and study and analyze the inherent influence mechanism between each variable. Before doing specific research, I consulted the papers and literature of many other outstanding scholars, among which Cheng Yuhong and Cheng Chi’s “The Influence Mechanism of industrial structure of urban and rural income gap” [1] has great reference value for this paper. According to the research results, under the background of high-quality development in the Yangtze River Delta region, the expansion of the income gap between urban and rural areas will inhibit the upgrading of the industrial structure, so it is necessary to focus on building a new type of urbanization, accelerating the construction of an urban innovation system, optimizing the rural employment structure to narrow the income gap between urban and rural areas, and providing impetus for the continuous upgrading of the industrial structure. 展开更多

As a priority of China’s regional development strategy in recent years, promoting the ecological protection and high-quality development of the Yellow River Basin is one of the important tasks to boost the country’s economy and also the key to the development strategy in the central region at this stage. High-quality development of the Yellow River Basin based on the perspective of culture, sports, and tourism integration is significant for the regional ecological protection and economic revitalization. In order to measure the development of culture, sports, and tourism resources in the basin, the study applied the CRITIC model in Mathematical Statistics, the fuzzy comprehensive evaluation model, and the entropy weight TOPSIS analysis model. The results indicated that the development of the three resources in the basin varies from region to region, among which Shaanxi, Shandong, and Henan provinces have developed outstandingly while western provinces in China haven’t. In addition, this study identified the spatial geographic extent and analyzed the POI (points of interest) of culture, sports, tourism, and mixed resource based on the data analysis to explore the spatial distribution characteristics and trend of changes in the Yellow River Basin. The study also made suggestions for the development of culture, sports, and tourism resources in the basin from different perspectives based on the developed theoretical model, aiming to promote high-quality development of the area. 展开更多

The rapid increase in the proportion of cash crops and livestock production in the Yangtze River Basin has led to commensurate increases in fertilizer and pesticide inputs. Excessive application of chemical fertilizer, organophosphorus pesticides and inappropriate disposal of agricultural waste induced water pollution and potentially threaten Agriculture Green Development(AGD). To ensure food security and the food supply capacity of the Yangtze River Basin, it is important to balance green and development, while ensuring the quality of water bodies. Multiple pollutants affect the transfer, adsorption, photolysis and degradation of each other throughout the soil-plant-water system. This paper considers the impact of multi-pollutants on the nitrogen and phosphorus cycles especially for crops, which are related to achieving food security and AGD. It presents prospective on theory, modeling and multi-pollutant control in the Yangtze River Basin for AGD that are of potential value for other developing regions. 展开更多

Territorial development suitability (TDS) distribution and policy implications in the Yangtze River Basin are investigated through the use of statistical and spatial data, using the Delphi method, the analytic hierarchy process method and the comprehensive evaluation model. The distribution pattern and characteristics of TDS in the Yangtze River Basin are studied, providing a scientific basis and a decision-making reference for sustainable development of the whole basin, and promoting reasonable implementation of the Yangtze River economic belt development strategy. The results show that the overall level of development constraint is relatively high, and that high-value regions (grades V-VIII) are mainly distributed in the upper and middle reaches of the basin. The suitable development regions account for 22.95% of the total basin area, mainly including the Yangtze River Delta region, the provincial capitals, the urban agglomerations and most prefecture-level cities. The variation of TDS is significant among the upper, middle and lower reaches of the basin, and the high-value areas account for 8.24%, 35.70% and 82.97% of the total areas of the upper, middle and lower reaches, respectively. Three policy suggestions are proposed: (1) strict control of the basin development intensity, setting up an efficient and well-organized spatial development pattern, (2) implementation of different regional policies according to different functional orientations, and (3) strengthening of communication and cooperation between different regions, thus promoting integrated basin protection and development. 展开更多

Over the past 20 years,China has experienced multiple economic transitions characterized by marketization,globalization,decentralization,and urbanization;as a result,urban land development intensity(ULDI)has become a significant issue for sustainable development.As China’s largest globalized urban area,the rapid socio-economic development of the Yangtze River Delta has created a huge demand for urban land.We apply a theoretical framework for a four-dimensional analysis tool to understand the dynamic evolution of the ULDI in the context of economic transition.It reveals that marketization,globalization,decentralization,and urbanization affect the ULDI in the economic transition of Yangtze River Delta.Marketization,especially the continuous improvement of land marketization,optimizes the spatial allocation of land resources and encourages urban land users to improve ULDI.Globalization promotes the rapid growth of economy and population through an increase in foreign direct investment.In the process of decentralization,local governments rely on developing a mode of land finance,resulting in a disordered urban space and low ULDI.Population growth and agglomeration during urbanization stimulates residents’consumption capacity and promotes economic growth,thus creating a greater demand for urban land.However,a low level of development and utilization restricts the improvement of development intensity.Economic development can improve the level of land-intensive use by promoting the adjustment,optimization,and upgrade of urban industrial structures. 展开更多

The Yangtze finless porpoise(YFP)is an endemic freshwater cetacean species that exclusively inhabits the middle and lower reaches of the Yangtze River basin.Since the late 1970s,the YFP has experienced a drastic population decline and was classified as critically endangered by the IUCN in 2013.To save this unique species,a range of integrated conservation measures have been implemented,including strengthening natural habitat protection(in-situ),enhancing insurance populations(ex-situ),and advancing captive breeding and research initiatives.These efforts have yielded significant progress in the conservation of the YFP.The natural population has been starting to increase after a sharp decline,and the establishment of three insurance populations has provided a solid foundation for recovery.Additionally,advancement in captive breeding and research has delivered crucial technical support for population conservation.As a flagship species of Yangtze River biodiversity and an indicator of the river’s ecosystem health,the YFP’s integrated conservation strategy not only benefits its own population but also offers valuable insights for the protection of other endangered aquatic spe­cies in the Yangtze River and other threatened small cetaceans worldwide. 展开更多

Land spaces function in capacities of urban development,agricultural production,and ecological conservation,among many others.Research of land space utilization efficiency(LSUE)and coupling coordination relationships among its subsystems are significant for sustainable land space development.In this study,taking the Urban Agglomeration in the Middle Reaches of the Yangtze River(UAMRYR)as the study area,we establish a measurement index system to evaluate the LSUE(2000–2018)and analyze its coupling coordination degree by utilizing an improved coupling coordination model.The main results include the following.(1)The average efficiency levels of urban space and agricultural space in the UAMRYR increased 2000–2018,while the average efficiency of ecological space declined.(2)The spatial pattern of the LSUE values varied greatly,with the distributions of high-efficiency and low-efficiency levels significantly different.(3)The coupling degree of LSUE includes three types,i.e.,high-level coupling,break-in,and antagonism.Each coupling degree type was characterized by change over time.(4)The proportion of areas with high coupling coordination and moderate coupling coordination increased from 2000 to 2018,while the proportion of areas with basic coupling coordination,moderate imbalance,and serious imbalance declined during this period.Given that the spatial differentiation of the LSUE and its coupling coordination,it is necessary to implement a differential land space development strategy in the UAMRYR.This study is helpful to promote the efficient utilization and coordinated development of land space utilization systems. 展开更多
