摘要：
This study uses Exploratory Spatial Data Analysis (ESDA) method and Logarithmic Mean Divisia Index (LMDI) model to analyze and discuss the Spatial-temporal pattern as well as the dominant driving factors of wastewater discharge in Yangtze River Economic Zone from 2002 to 2015. The paper indicates that: (1) In terms of the spatial-temporal pattern, the amount of wastewater discharge in Yangtze River Economic Zone shows an increase trend from 2002 to 2005, and then put up a decline trend between 2005 and 2015. Referring to the spatial characteristics, firstly, the amount of wastewater discharge increases from upstream to downstream. There are few high discharge cities whereas more low and middle discharge cities. Secondly, a certain amount of wastewater discharge transfers from the downstream to the midstream and upstream, and the wastewater discharge in mountainous area is lower than other regions. (2) In terms of the change of spatial relationship among cities in the research area, the wastewater discharge shows a significant spatial agglomeration. High discharge cities are concentrated in the Yangtze river delta and low discharge cities are distributed in underdeveloped areas in the western part of China, especially the tourism-oriented cities. (3) In terms of the driving factors, the technical improvement effect did a negative contribution and controlled the amount of wastewater discharge, whereas the industrial structure effect did a positive or a negative contribution depend on the policy and market. The economy development effect, which was one of the dominant factors, did a positive contribution to the amount of wastewater discharge. Moreover, the population scale effect did a positive contribution to the wastewater discharge, but the impact is not significant.

摘要：
Dramatically increased societal demands on the municipal services that contradict environmental protection and information processing capability oriented to resource utilization efficiency suffer from opposing simultaneous requirements. The smart city provides better solutions for urban areas which are increasing at an unprecedented speed. This paper presents an empirical study carried out to assess and analyze the development pattern of 35 smart cities in China using the principal component analysis (PCA) and back propagation (BP) neural network techniques. The proposed PCA-BP neural network assessment processing model is applied with six dimensional factors and twenty-two operating indices. With the feature extraction and performance score calculated via PCA, BP neural network is adopted for city classification to recognize the development differences in smart cities. The results indicate that the factor-driven impetus evolves into innovation-driven impetus, narrowing the gap from the holistic perspective between the first and middle-ranking groups, while two middle-ranking groups show a similar upward trend in terms of developing a smart economy through sustainable productivity in innovative enterprises and high-tech industry. To some extent, in response to a similar improving trend in the application of smart services, a distinct advantage of an individual index can be a complementary offset to unapparent holistic highlighting the reception of the lowest average points. Unbalanced development exists in two subaverage groups that are deficient in the initial inventory of smart infrastructure and demands. A relatively large difference exists in the smart mobility index among cities, whereas the opposite case is found concerning the smart environment index. Finally, corresponding optimized development pattern are recommended for building a sustainable smart city. (C) 2019 Elsevier Ltd. All rights reserved.

摘要：
In a city, housing price varies with location. Thus, housing price plays an important role in detecting the spatial pattern of the city. Spatial interpolation methods have been widely used for simulating and predicting urban housing prices. In this paper, the Ordinary Kriging interpolation method is used for producing the digital elevation model (DEM) of urban housing prices. Based on the three-dimensional DEM of urban housing price, this paper develops a novel approach for geo-visual analytics of urban housing prices. To investigate and visualize the spatial morphology of housing price, we design the Water-flooding, Section-cutting and Belt-floating methods, and implement these methods with the 3D-analyst module in GIS environment. Then, we take Wuhan City as a case, apply this approach to analyze the complex spatial morphologic characteristics of the DEM for housing price and visualize the results from the multidimensional perspectives. The results show that the Water-flooding method effectively supports the investigation of the top areas of surface changes; Section-cutting method performs well in examining the profile or cross-section of the urban housing surface; and Belt-floating method is helpful for detecting the spatial variance of the urban housing surface through the routes of specific lines. The results demonstrate that the proposed approach works better than traditional methods in describing the complex spatial morphology of urban housing prices, and has an advantage in visualizing the analysis results.
摘要：
Economic growth and eco-environmental protection are largely incompatible in the optimization of the urban land-use structure (ULUS) in rapidly developing regions. Here, we attempted to construct a model for optimizing ULUS with the inclusion of uncertain interval values, simultaneously considering the economic growth and eco-environmental protection in rapidly developing regions so as to estimate the elastic interval value of ULUS. The corresponding urban economic and environmental benefits were analyzed. Furthermore, an empirical study of Wuhan city revealed that there are certain counterbalance relationships among commercial land, industrial land and green land: the area of residential land, green land and public land is increasing year by year, and that of industrial land remains basically unchanged, while that of commercial land is decreasing gradually. Therefore, in rapidly developing regions, greater economic benefits from the ULUS are usually obtained at the cost of environmental and ecological benefits.

摘要：
Noise pollution poses negative impacts on public health particularly for urban dwellers as the land use of cities is prone to producing more road traffic and various human activities. Among the existing literature, the pathways linking built environment characteristics and noise level are not sufficiently addressed owing to a variety of complex factors affecting noise in urban areas. This study aims to examine the relationships of urban built environment and noise, using Pearson correlations and multiple linear regressions. Built environmental factors considered for this study consist of land cover, land use, and urban form. Results reveal a significant association between three aspects of urban built environment and noise level. In terms of land cover, forest alleviates noise effectively, while the effect of grassland on noise is far less impactful than forest. High-density and high-rise building areas (HHBA) are two contributors to noise pollution. The spatial layout of residential buildings is more effective in reducing noise level, as compared to the size of the residential lands. In terms of land use, the area proportion of business, open space with hard pavement, industrial, and residential land uses positively influence noise level. In terms of urban form, controlling building density is a key measure in noise reduction. Buildings with larger site coverage and complex shapes are effective in noise reduction. Findings from this study would be very helpful to formulate and implement effective measures for noise pollution mitigation, and ensure sustainable development of urban environment.
摘要：
Finding ways to identify the coupled relationship between changes in the quantity and quality of ecologically functional land (EFL) is essential for sustainable ecosystem management. However, this coupled relationship has been ignored in the literature. This paper proposes a quality-based quantity (QBQ) method to evaluate the spatiotemporal change in EFL in China. Three Landsat images spanning 20 years were used to investigate the gains and losses of EFL. We compared the differences and linkages between the net change and QBQ change of EFL at the county scale. Continuous EFL loss and growing fragmentation were observed in China. From 1995 to 2015, the main cause of EFL loss was desertification, followed by farmland occupation and construction land consolidation. It should be noted that the EFL loss from 2005 to 2015 was much higher than that from 1995 to 2005. The main gain in EFL was from desert land exploitation, followed by farmland return and construction land consolidation. In particular, grassland degradation was the most severe ecological problem in western China. The QBQ change in EFL showed a more severe situation than did the quantity change. The dynamic processes associated with quantity change and their effects on landscape were well reflected in the QBQ change. These results indicated that the EFL degraded in both quantity and quality in China between 1995 and 2015. EFL conservation policies should focus not only on the dynamic losses and gains in quantity but also on the changes in quality linked to landscape patterns. (C) 2019 Elsevier Ltd.

摘要：
OBJECTIVE: To assess the joint cumulative effects of medical insurance and family health financial risk on healthcare utilisation among patients with chronic conditions in China. DESIGN: A nationwide population-based case-control study with multinomial logistic regression was conducted and used to estimate the ORs of healthcare utilisation against type of medical insurance and family health financial risk using the Anderson model as a theoretical framework. SETTING: China Family Panel Studies (CFPS) database. PARTICIPANTS: The study sample included 5260 patients with chronic conditions identified from the 2014 CFPS database. MAIN OUTCOME MEASURES: The participants were classified by their health insurance coverage: urban employee basic medical insurance (UEBMI), Gong Fei Medical Insurance (GFMI), new rural cooperative medical scheme (NCMS) and urban residents basic medical insurance. Healthcare utilisation was measured by assessing the care level provided by the health institutions selected by patients when they were sick. Health financial risk was measured using the cost of medical expenditures and annual family income over the past year. RESULTS: Patients were more likely to choose hospital care than care from primary health centres. Patients with NCMS preferred primary healthcare, compared with patients with no medical insurance (OR 1.852, 95% CI 1.458 to 2.352). Patients with UEBMI and GFMI made use of hospital healthcare services (OR 2.654, 95% CI 1.85 to 3.81; OR 1.629, 95% CI 1.15 to 2.30, respectively). Patients who had medium or high financial risk were more likely to choose tertiary/specialised hospital care, compared with those at low financial risk (OR 1.629, 95% CI 1.15 to 2.30; OR 1.220, 95% CI 1.04 to 1.43, respectively). CONCLUSIONS: The majority of patients chose hospital care in our sample. There was a joint effect and relationship between degree of family health financial risk and medical insurance on healthcare utilisation.

摘要：
Based on Theory of Evidence and reviewing research papers concerned, a concept model of knowledge sharing network among industrial cluster firms, which can be applied to assess knowledge sharing capacity, has been built. Next, the authors create a set of assessment index systems including twelve subindexes under four principle indexes. In this study, ten experts in the same field were invited to score all the indexes of knowledge sharing capacity concerning one certain industrial cluster. The research result shows relatively high knowledge network sharing capacity among the certain industrial cluster firms. Another conclusion is that the assessment method with Theory of Evidence is feasible to conduct such a research.
