In tourism studies, new means of data collection are opening up opportunities for disclosing hidden mobility patterns. This paper aims to analyze and model the tourist flow networks different lengths trip on urban scale, using user generated content (UGC) collated from an open web service. The textual UGC data, with high spatial temporal resolution, is utilized construct three in response length trips. Social network analysis a revised interaction deployed exploring heterogeneity movements....

The inequities in healthcare services between regions, urban and rural, age groups diverse income have been growing rapidly China. Equal access to basic medical has recognized as "a right of the people" by Chinese government. Spatial accessibility facilities received huge attention case studies but less studied particularly at a county level due limited availability high-resolution spatial data. This study is focused on measuring Deqing County. inequity (town) rural assessed three scenarios...

Implementation of the Healthy China Strategy and hierarchical diagnosis treatment system has injected new vitality into medical services. Given insufficient supply services increasing demand for treatment, exploring supply-demand pattern become an urgent theoretical practical problem to be solved. The equity healthcare facilities received widespread attention, but due limited data, there is little research on This study focuses evaluating matching at different levels in Haikou City with big...

Abstract The source region of the Yellow River is an important ecological barrier Qinghai-Tibet Plateau in China. In recent decades, environment has been deteriorating continuously, which not only endangers living region, but also seriously hinders sustainable development regional ecology, society and economy. At present, interaction mechanism among land use, landscape pattern driving factors revealed. Based on remote sensing image data past 30 years, evolution law was analyzed by transfer...

Due to the emergence of new big data technology, mobility such as flows between origin and destination areas have increasingly become more available, cheaper, faster. These improvements infrastructure boosted spatial temporal modeling OD (origin-destination) flows, which require consideration dependence heterogeneity. Both ordinary least square (OLS) negative binomial (NB) regression methods been used extensively calibrate flow models by processing different types dependent variables. This...

The tourism efficiency in scenic areas is influenced by multi-factor joined effects, presenting multi-scale fluctuation characteristics temporal terms and regional differences spatial terms. This paper, adopting the data envelopment analysis (DEA) method Bootstrap-DEA model, calculates their decomposition efficiency. Then, based on methods of empirical mode decomposition, wavelet Morlet paper reveals characteristics, process its differentiation change from perspective time–frequency domain,...

This article measures and calculates tourism efficiency in Chinese national scenic areas. In order to analyse the characteristics of multi-scale fluctuations, empirical mode decomposition (EMD) wavelet methods are adopted. Specific areas divided into several zones, with conclusions provided about impact economic fluctuations on their efficiency. The results as follows. overall is not high; most have yet reached data envelopment analysis (DEA) optimization; quasiperiodicity areas’ mainly...

Objective: To investigate the role of "Hong's single-stitch duct to mucosa pancreaticojejunostomy(HSDMP)" in laparoscopic pancreaticoduodenectomy (LPD). Methods: The clinical data including perioperative and short-term outcomes 51 cases LPD with HSDMP which performed Zhejiang Provincial People's Hospital(33 cases) Frist Clinical Hospital Jilin University(18 between April October 2016 were reviewed retrospectively. There 31 male patients 20 female patients. mean age was(59±11)years. Body mass...

Consensus filtering is an effective method for distributed state estimation of sensor networks and the assumption white measurement noise widely used. However, when colored, traditional consensus filter cannot work well. In this paper, we first propose a consensus-based colored by augmenting to include noise. To improve efficiency filter, only local integrated into augmented each filter. Furthermore, another based on differencing scheme developed eliminate ill-conditioned computations...

With sea level predicted to rise and the frequency intensity of coastal flooding expected increase due climate change, high-resolution gridded population datasets have been extensively used estimate size vulnerable populations in low-elevation zones (LECZ). China is most populous country, its LECZ grew rapidly urbanization remarkable economic growth areas. In assessing potential impacts hazards, spatial distribution exposure China’s should be examined. this study, we propose a combination...

Producing gridded electric power consumption (EPC) maps at a fine geographic scale is critical for rational deployment and effective utilization of resources. Brightness nighttime light (NTL) has been extensively adopted to evaluate the spatial patterns EPC multiple geographical scales. However, blooming effect saturation issue NTL imagery limit its ability accurately map EPC. Moreover, limited sectoral separation in applying leads inaccurate distribution EPC, particularly case industrial...

The data regarding resources and environmental carrying capacities (RECC) are not only the basis for realizing regional sustainable development, but also core links major function-oriented zoning practices, which include specific partitioning schemes of spatial units with various geographical functions. Previously, relevant studies were mainly based on evaluations single factors. However, realization practices comprehensive assessments RECC has been neglected. This study presented an...

Scale is a fundamental geographical concept and its role in different contexts has been widely documented. The increasing availability of transport mobility data, the form big datasets, enables further incorporation spatial dependencies non-stationarity into interaction modeling flows. In this paper newly developed multiscale flow-focused geographically weighted regression (MFGWR) approach applied, addition to global local Moran I indices flow model socio-economic determinants regional flows...

Based on the road network in Yangtze River Delta (YRD), and using geography information system technology, this article quantitatively evaluates travel convenience for residents with regard to accessibility of scenic spots, both inside outside Delta. It shows that tourist attractions reflects centricity their location, score figure YRD presents a circular structure Taihu Lake at center. Furthermore, outward indicates is high west low east, best areas distributed along Nanjing–Hangzhou...

In this paper, we develop a new method to calculate regional accessibility with geography information system (GIS), using the Shanghai–Nanjing high-speed rail (SNHR) as an example. We calculated indexes of normal accessibility, average and weighted before after SNHR was put into service. also changes indexes. The results showed that values all decreased improved by SNHR. But, reduction degrees were not same in different places. addition, discussed potential impact changes. Accessibility will...

Social vulnerability assessment has been recognized as a reliable and effective measure for informing coastal hazard management. Although significant advances have made in the study of social over two decades, China’s profiles are mainly based on administrative unit. Consequently, no detailed distribution is provided, capability to diagnose human risks hindered. In this study, we established index (SoVI) 2000 2010 at spatial resolution 250 m zone by combining potential exposure (PEI)...
