“…Thus, more attention should be paid to the drastic expansion of urbanization. Many studies have been conducted worldwide [1], including in regions of Africa [10], Europe [11], Latin America [12], North America [13], and Asia [14][15][16]. Previous studies have also explored the mechanisms of many cities, population and income related to urban and transforming in the process of modernization.…”

Urbanization challenges regional sustainable development, but a slight expansion mechanism was revealed in a plateau city. We have integrated the urban expansion process and analyzed its determinants in Lhasa (Tibet), and we provide insightful suggestions for urban management and planning for Lhasa. The full continuum of the urban expansion process has been captured using time-series of high-resolution remote sensing data . Four categories of potential determinants involved in economic, demographic, social, and government policy factors were selected, and redundancy analysis was employed to define the contribution rates of these determinants. The results illustrate that considerable urban expansion occurred from 1990 to 2015 in Lhasa, with the area of construction land and transportation land increasing at rates of 117.2% and 564.7%, respectively. The urban expansion in the center of Lhasa can be characterized as temperate sprawl from 1990 through 2008, primarily explained by governmental policies and investment, economic development, tourist growth, and increased governmental investment resulting in faster urban expansion from 2008 to 2015, mainly occurring in the east, south, and west of Lhasa. In contrast with other cities of China, central government investment and "pairing-up support" projects have played an important role in infrastructure construction in Lhasa. The miraculous development of the tourism industry had prominent effects on this economic development and urbanization after 2006, due to the running of the Tibetan Railway. An integrative and proactive policy framework, the "Lhasa development model", having important theoretical, methodological, and management implications for urban planning and development, has been proposed.

“…The high risk areas correspond to high hazard and vulnerability which are extremely prone to flood and also vulnerable to these hazards from point of socio-economic (Pandey et al, 2010). Land use transformation is very useful using satellite data in GIS environment in order to monitor land consumption rate (Kumar et al, 2011). Very significant studies on Kashmir valley lakes (Hamilton and Schaldow, 1997;Subramanium, 2000;Bhatt, 2004;Agarwal et al, 2012) indicated the aspects of high altitude lakes in India.…”

ABSTRACT:Wular lake, located at an elevation of 1520 m above sea level in Kashmir valley, India. In the present study, the immediate and long term impact of flood (2014) over the Wular lake environs was analyzed by using satellite images and employing supervised classification technique in GIS environment. The LULC classification was performed on the images of 25 th August 2014 (pre flood) and 13th September 2015 (post flood) and was compared, which indicated marked decrease in terrestrial vegetation (23.7%), agriculture (43.7%) and water bodies (39.9%). Overlaying analysis was performed with pre and post flood classified images with reference to the satellite image of 10 th September 2014(during flood) which indicated total area inundated during flood was 88.77 km 2 . With the preflood situation, the aquatic vegetation of 34.06 km 2 , 13.89 km 2 of agriculture land and terrestrial vegetation of 3.13 km 2 was inundated. In the post flood situation, it was also came into focus that more than the half of the area under water bodies was converted into sand deposits (22.76 km 2 ) due to anomalous increase in siltation. The overlay analysis on post flood classified image indicated that aquatic vegetation followed by agriculture and sand deposits lie within the flood inundated area. Further spatial analysis was performed within the flood inundated area (88.77 km 2 ) with pre and post classified image to understand the situation before and after the flood and to calculate the changes. These land use-land cover transformations signifies the ill effect of flooding on the biodiversity of Wular Lake.

“…They mainly focus on the following several aspects. (1) GIS technology and spatial modeling have been widely introduced to investigate landscape change and the spatial patterns of urban expansion (Verburg et al, 1999;Xiao et al, 2006;Liu and Zhang, 2008;Kumar et al, 2011;Wang et al, 2012a;Gao et al, 2013;Mondal et al, 2015;Zeng et al, 2015;Zhao et al, 2015). For example, Xiao et al (2006) categorized spatial patterns into special objectives, social-political intervention, and normal urban growth.…”

a b s t r a c tChina has been experiencing rapid urbanization, with a large amount of rural land converted into urban land, leading to debate by researchers and governments. This study investigates the endogenous factors influencing urban expansion and quantifies their effects to promote intensive and sustainable urban land use in order to realize new-type urbanization, by employing GIS technology and an endogenous growth model. The simulation results explain the expansion of urban land in the case of Baotou city, China. The result shows that the land management institution(LMI) has played a critical role in urban land expansion in Baotou city. Its multiplier effect reaches 0.166, which means a one percentage point increase in the strength of LMI leads to a 0.166% increase in urban land area. The presented analysis reveals four main findings. Firstly, the major factors influencing urban expansion are (LMI), urban disposable income per capita, the secondary and tertiary industry, technological progress, and population density. Secondly, LMI has a critical influence on urban expansion. Thirdly, technological progress has a positive effect on urban expansion by merging into the secondary and tertiary industry. Finally, population density and the tertiary industry have a dampening effect on urban expansion. According to the analysis, we suggest that the central government in China should regulate the behavior of local governments to reduce principal-agent risk, as they hold the state land property rights as the trustee of the public. Meanwhile, the government should pay more attention to guiding technological progress by promoting industrial transformation and economic quality, not just focusing on economic quantity, especially for resource-based cities.
