Abstract The coordinated development of land and water resources and the ecological environment is essential to regional sustainable development. In view of the current rapid development of information science, the coordination degree of eco-environmental systems has been evaluated from the perspective of development rate. Taking the major grain-producing areas in China as an example, this study used information entropy to determine the weights of various indicators and introduced the average annual growth rate to characterize the development rates of indicators. Through an improved dynamic coupling and coordination model, the coupling and coordination indices of the system and subsystems of land and water resources with the ecological environment were obtained. These indices were analyzed and compared with those generated from raw data. The results showed that during the study period, the land and water resources and the ecological-environmental system had a relatively low coupling, with reluctant coordination, and had a relatively low level of coordinated development. Compared with the results based on raw data, the development rate method yielded similar results on the coupling of subsystems. For the analysis of trends, the method using development rate characteristics better reflected the overall coupling of the system, as well as the coordination of the system when considering the range of relative changes. Therefore, evaluation results based on development rate characteristics can, to a certain degree, better help decision-makers timely understand the coordinated development of the land and water resources and the ecological-environmental system.

With the rapid development of economy, the scale of the logistics industry is also expanding rapidly, which brings great convenience to economy and trade, and becomes one of the pillar industries of national economy. However, with the development of economy and logistics, the problem of ecological environment is becoming more and more prominent. Through the design of economic development, logistics development, and the ecological environment index system, the economic development, logistics development and eco-environment development level of 30 provinces and cities in China from 2008 to 2017 are analyzed by using the entropy method and coupling coordination degree model, and the spatial characteristics of regional economic development, logistics development, and ecological environment are analyzed by using ArcGIS software. The results show that the coupling coordination of economic development, logistics development and ecological environment in most provinces and cities in China is at the mediate coupling level, and only Shanghai, Anhui, and Fujian in the Eastern region have reached the high-quality coupling level; there are significant temporal and spatial differences in the coupling and coordinated development between economic development, logistics development and ecological environment. The level of coupling coordination in the western region has always been at a low level, while the level of coupling coordination in most of the central and eastern regions is relatively high. There are situations where the level of coupling coordination is not high; the coordinated growth of economic development, logistics development, and ecological environment is mainly driven by economic development and logistics development. However, the level of ecological environment has been lagging behind the level of economic and logistics development. In the future development, it is necessary to give full play to the role of the logistics industry in economic development, weigh the relationship between the development of the logistics industry and ecological environmental protection, actively develop green logistics, and the level of coordinated development among economic development, logistics development and ecological environment.

Abstract Coupling and coordination analyses of regional water resource systems (WRS) play an important role in promoting the sustainable and coordinated development of those systems. In this paper, a dynamic coupling coordination model is introduced to study the coordinated development of WRS. The weight of each index is obtained using an improved entropy weight method. The coupling and coordination degrees between resource subsystems and other subsystems and an entire system of water resources can be obtained using this model. Taking Heilongjiang, China, as an example, the results show that in 2005–2014, the WRS exhibited low coupling and low coordination characteristics due to a substantial contradiction between the resource subsystem and the social and economic and ecological subsystems. Therefore, strengthening the overall development of water resources, society, economy and ecology and improving the coupling abilities between resource subsystems and each of the other subsystems are effective strategies for promoting the coordinated development of WRS.

Coordinated Development Degree

Water resources utilization, social economy development, and ecological environment protection are key factors in regional sustainable development. Scientific evaluation of regional coordinated development status and diagnosis of regional uncoordinated development constraints will improve the management level of decision-makers. At present, most developing countries have the problem of unbalanced regional development caused by the one-sided pursuit of a certain system. Taking 14 prefecture-level cities in Hunan Province as cases, this paper analyzed the spatial and temporal distribution characteristics of the carrying capacity level of the water resources system, the development level of the social economy system and the protection level of the ecological environment system in each evaluation unit based on entropy weight method and order parameter analysis. Based on the theory of coordinated development, a calculation model of a coordinated development degree was constructed, and the corresponding evaluation criteria were formulated. The spatial and temporal distribution characteristics of a coordinated development degree in each research unit were analyzed and evaluated. The results showed that the average coordinated development degree of Hunan Province from 2004 to 2016 evolved from “Light disorder recession” to “Nearly disorder recession”, then to “Reluctance coordinated development”. Restricted by different systems, the coordinated development degree in each research unit presented spatial and temporal differences. According to different development stages and the characteristics of different regions, corresponding development strategies can be formulated to provide the guidance for coordinated the development of regions.

China is a country where the levels of water resources per capita are extremely low. With the rapid development of urbanization, water resource shortages have become a bottleneck existing in more and more cities. This study considers the comprehensive management of urban flood control, water supply, water and the ecological environment, catches the main contradiction between “water deficient” and “water rich” in cities, puts forward a comprehensive utilization pattern for urban water resources by emphasizing the utilization of rain–flood resources. After a simulation study, a better regulation pattern is brought out and achieve multiple benefits based on the river system of Gucheng Lake, which is located in Nanjing, Gaochun district, by optimizing conventional regulation. The results show that two parameters, the low water level (LWL) below which Gucheng Lake stops supplying ecological water, and the high water level (HWL) where Gucheng Lake stops importing water from rivers, are the key parameters to decide the regulation benefits, and the LWL of 9 m and HWL of 12 m is the best combination in river network regulation, the annual potential utilizable of rain–flood resources of Gucheng Lake river system can reach 57 million m3 per year, through the comprehensive utilization of the rain–flood resources, the negative effect of flood is effectively reduced and the disaster is controlled on one hand; and the water demand of urban and rural water supply, 100,000 m3/day, is effectively guaranteed as well as the regional ecological environment is improved on the other hand.

Due to the rapid development of the modern chemical industry, a large amount of chlorophenol pollutants remain in the environment. It poses a serious threat to the ecological environment and human health. Advanced oxidation technologies (AOPs) have the characteristics of mild reaction conditions and strong oxidation capacity, and are currently recognized as safe and effective pollutant treatment technologies. In this study, natural lead-rich biochar materials were used to activate sodium persulfate to degrade 2,4-dichlorophenol, and natural lead-rich biochar modified TiO2 photocatalytically degraded 2,4-dichlorophenol. Then, using natural lead-rich metal biochar/TiO2 material, photocatalysis combined with active sodium persulfate to degrade 2,4-dichlorophenol. The experimental results show that the combination of photocatalysis and activated sodium persulfate reaction can completely degrade 100 mg/L 2,4-dichlorophenol under UV light for 3 h, and the degradation efficiency is much higher than the sum of the two separate reactions. Quenching experiments show that SO4- • radicals play the most important role in the three free radicals (SO4- •, •OH and •O2- ) in the advanced oxidation combination system. Finally, the reaction mechanism of the two advanced oxidation combined systems are speculated.
