Yet, systematic research on spatio-temporal urbanization patterns and drivers along the urban–rural gradient is rarely reported for northwest China. Here, we use land-use data from 1980 to 2015 to explore land-use change, urbanization intensity, and drivers in northwest China. Our results display direct and indirect effects of urban expansion on farmland loss, but also spatio-temporal heterogeneity in the urbanization patterns. While the earlier years were dominated by infill and land conversion close to city centers, the later years displayed sprawling urbanization following the constraints of terrain and administrative boundaries at the cost of farmland. Our regression analysis of spatial variables found a strong relationship with urban planning factors. The spatial analysis of urbanization patterns revealed indirect land-use change on former farmland. Furthermore, we found that regional geography and historic sites considerably influenced land conversion. Overall, our findings indicate the need for sustainable planning strategies that synthesize approaches to farmland and historic site protection and consideration of regionally specific landscape characteristics.

First, we digitized the topography map, vegetation map, river map, road map and villages/ towns map by ArcInfo, and gave each map layer a suitability index based on our perceptions of the needs of crested ibis. Second, we overlayed these maps to obtain an integrated map of habitat quality. Finally, we compared the calculated habitat quality with the actual distribution of crested ibis. We found that the birds were almost always located at the site of high quality (habitat suitability index [HSI] > 0.6), which indicated that the factors we selected were important for crested ibis. We also found that crested ibis were never located at some sites of high quality, thus, we assume that other factors not considered in this study limit the distribution of crested ibis. Regression analysis indicated that crested ibis preferred lower elevation habitats and tolerated higher levels of human disturbance in recent years than previously reported.

  • 1 China Xi'an-Ankang Railway Construction Project
    China Xi’an-Ankang Railway Construction Project (1)-(3) (CXVII-P73, CXVIII-P73, CXIX-P73) External Evaluator: Mitsue Mishima (OPMAC) Field Survey: October 2004 1. Project Profile and Japan’s ODA Loan Mongolia Beijing North Korea China South Korea Project site Xian Nepal Ankang Bhutan India Taiwan Myanmar Vietnam Laos Project site location map (Xian-Ankang, Shannxi Province) Qingcha Tunnel 1.1 Background The project site (Xian- Ankang) is located in the southern part of Shaanxi Province where the 3000-meter high Qinling Mountains extend over 1500 kilometers, and was therefore undeveloped due to difficulties in transportation and remoteness from cities. Southwest of the project site is Sichuan Province, the largest province with a population of 110 million accounting for 10% of the population of China. However, as there is no other transport route to Sichuan Province than taking a detour around the Qinling Mountains, there were only limited routes to transport energy and everyday commodities from the north. Railway transport from other regions to Sichuan Province depended on Baoching Line (Baoji-Chengdu) from the north and Xiangyu Line (Xiangfan-Ankang-Chongquing) from the east, and both lines were operating to full capacity. It was particularly difficult to double-track Baoching Line, which takes a detour to avoid the Qinling Mountains because of 1) long distance of transport, 2) large cost to transport on a gradient at an angel of 3%, and 3) the topographical problem. The opening of the electrified single track of Xian-Ankang Line not only helped increase the transport capacity within Shaanxi Province but also shortened the traveling distance to Chongquing and eased the transportation load on Baoching Line.

  • Third Party Evaluator's Opinion on Xi'an-Ankang Railway Construction
    Third Party Evaluator’s Opinion on Xi’an-Ankang Railway Construction Project (1)-(3) Qunren Li Research Professor China Academy of Railway Sciences Impact As has expounded upon in the Ex-post Evaluation Report, the construction and operation of the Xi’an-Ankang railway has helped push economic development in the zone of impact by increasing the freight transportation volume, those of ores of various kinds in particular. In a similar manner, the increased passenger transportation volume with the construction of the line has also brought economic benefits to the region. Apart from Xi'an and Ankang, major cities at the two ends, an important administrative district that the Xi'an-Ankang railway passing through is Shangluo (consisting of Zhashui county and Zhen'an county), a city located in the Qinling mountainous area which, before the construction of the Xi'an-Ankang railway, suffered slow economy development and urban construction due to poor communication. The city enjoys many natual advantages for development: close to provincial capital Xi'an city, with a climate of pleasant cool in summer, little air pollution and nice scenery, which makes it a nature summer resort and offers a prospect of turning into the "back garden" of Xi'an city. Yet the handicapped traffic to Xi’an before the construction of the Xi’an-Ankang railway, taking more than more than 5 hours, made its advantages unable to be brought into play . Now the communication has become a lot convenient with the travel time between Xi'an and Shangluo shortened to a little more than 1 hour.

  • Analysis of Rural Women's Economic Participation in Shaanxi Province, China: Preliminary Results and Insights Mei Yang Allan R
    Analysis of Rural Women’s Economic Participation in Shaanxi Province, China: Preliminary Results and Insights Mei Yang Allan Rae David Tripe Martin Young Huiyan Zhao School of Economics and Finance, Massey University ABSTRACT China has made significant progress in economic reform. This has entailed large scale migration and urbanization, but there is an accompanying problem of position of women in agricultural production in rural areas. To explore this, the study examines rural women’s barriers and potential in economic participation in Shaanxi province through a survey of 356 rural women including both those engaging in farming and off-farming activities from three regions of Shaanxi with different developing characteristics. We use a mixed research methodology with both qualitative and quantitative elements. Unlike a handful of previous relevant studies, the collection of primary data allows a more in depth and systematic analysis of the current situation of rural women and the barriers they are facing. Preliminary results indicate that the situation of rural women in China presents a range of characteristics due to political factors, geographical location, low education attainment, and their role as care-providers. The results presented here here is mainly concerning the part of rural women engaging in farming. 1. Introduction Over the last three decades, China’s industrialization and urbanization have been on an unprecedented scale(Bank, 2014): Around 250 million migrants have moved to cities from rural areas (NBSC, 2012) in supporting the country’s rapid economic growth which has averaged around 10% annually. Meanwhile, starting from 2000, the number of left-behind rural women1 or using a specific term in Chinese, Liushou women has increased sharply and it still increases each year.

  • A Case Study on COVID-19 Infections in Shaanxi Province, China
    www.nature.com/scientificreports OPEN Health‑seeking and diagnosis delay and its associated factors: a case study on COVID‑19 infections in Shaanxi Province, China Wenyuan Zheng1, Fabrice Kämpfen2 & Zhiyong Huang3* This time‑to‑event study examines social factors associated with health‑seeking and diagnosis of 165 COVID‑19 cases in response to the pandemic spread in Shaanxi Province, China. In particular, we investigate the diferential access to healthcare in terms of delayed time from symptom onset to frst medical visit and subsequently to diagnosis by factors such as sex, age, travel history, and type of healthcare utilization. We show that it takes more time for patients older than 60 (against those under 30) to seek healthcare after developing symptoms (+ 2.5 days, p < 0.01 ), surveillance on people with living or travel history to Wuhan helps shorten the time to the frst doctor visit (− 0.8 days) and diagnosis (− 2.2 days, p < 0.01 ). A delay cut is associated with the adoption of intermediary and large hospitals rather than community‑based care as primary care choices (− 1.6 days, p < 0.1 and − 2.2 days, p < 0.05 ). One unit increase of healthcare workers per 1000 people saves patients 0.5 days ( p < 0.1 ) for diagnosis from the frst doctor visit and 0.6 days ( p < 0.05 ) in total. Our analysis of factors associated with the time delay for diagnosis may provide a better understanding of the health‑ seeking behaviors of patients and the diagnosis capacity of healthcare providers during the COVID‑19 pandemic. In December 2019, a series of unknown-cause pneumonia cases, later named COVID-19 by the World Health Organization (WHO), were reported in Wuhan, China, and has since spread rapidly, becoming a global pan- demic within months.
