  • Analyzing Ecological Functions in Coal Mining Cities Based on RS and GIS
    Pol. J. Environ. Stud. Vol. 27, No. 3 (2018), 1165-1174 DOI: 10.15244/pjoes/75190 ONLINE PUBLICATION DATE: 2017-12-13 Original Research Analyzing Ecological Functions in Coal Mining Cities Based on RS and GIS Ling Liu1, 2, Jinsheng Zhou1, 2* 1School of Humanities and Economic Management, China University of Geosciences, P. R. China 2Key Laboratory of Carrying Capacity Assessment for Resource and Environment, Ministry of Land and Resources, Beijing 100083, China Received: 16 March 2017 Accepted: 21 June 2017 Abstract Ecological problems have long been a hard issue in mining cities. This paper tried to present ecological functions in mining cities from two aspects: landscape ecology and ecological carrying capacity. The city of Qitaihe, one of the coal cities in Heilongjiang Province in northeastern China, was chosen as a typical study area. Remote sensing data from 1957, 1985, 2000, and 2015, and geographic information system (GIS) techniques were employed to obtain land use and cover information. Methods of landscape pattern indexes and a modified model of ecological carrying capacity which added social and economy index were used to study the spatial and temporal variation of the ecological condition. Results showed that the landscape pattern changed tremendously during the study period due to interference from human activity. The degree of aggregation, dominance, and fragmentation of mining land showed an increasing trend. On the other hand, the ecological carrying capacity per capita declined by 37.4% from 1985 to 2000. Except for the growth of population, the dim social and economic conditions had an impact on this decline too. In addition, spatial distribution of land types and ecological carrying capacity also had some correlation with the city’s overall planning.

Financial projections and analysis have been prepared in accordance with the 2005 edition of the Guidelines for the Financial Governance and Management of Investment Projects Financed by the Asian Development Bank. The Guidelines cover both revenue earning and non revenue earning projects. Project roads include expressways, Class I and Class II roads. All will be built by the Heilongjiang Provincial Communications Department (HPCD). When the project started it was assumed that all project roads would be revenue earning. It was then discovered that national guidance was that Class 2 roads should be toll free. The ADB agreed that the DFR should concentrate on the revenue earning Expressway and Class I roads, 2.

    Advances in Social Science, Education and Humanities Research, volume 194 4th International Conference on Education Technology, Management and Humanities Science (ETMHS 2018) Estimation of Ecological Compensation Rates for Transboundary Watershed Based on Emissions Trading ——A Case of Songhua River Basin Li Wanhong1, a, Wang Fuyao1, b, * 1School of Economics and Management, Harbin Engineering University, Harbin 150001, China [email protected], [email protected] Keywords: Songhua River basin, emission rights, ecological compensation standard Abstract: Based on the theory of emissions trading, this paper constructs a panel data model based on Kuznets curve (EKC) and ecological compensation standard calculation model. Taking data of seven cities from Songhua River basin such as Jilin, Changchun, Songyuan, Qiqihar, Harbin, Qitaihe, Jiamusi, the paper also calculates their ecological compensation rates in 2004 and 2015 based on the trading of emission rights, and does longitudinal analysis of the ecological compensation standards of Changchun and Harbin. The results show that cities with transboundary basins should follow the principle of "who pollutes who pays", and cities that overuse the right to emit pollutants should pay more ecological compensation, while the economically viable cities will receive corresponding ecological compensation, which will help clear cross-border river basin water pollution control responsibilities, and improve pollution control efficiency. 1. Literature Review Due to the fluidity of water resources and the characteristics of public resources, watershed management involves the vertical affiliation between the upper and lower levels of government and the horizontal parallel relationship between governments at the same level. This complex multi-tiered relationship leads to controversy over water quality issues in the upper and lower reaches of the basin.

As the widespread cascading failure may cause serious damage, factor identification is necessary to improve the security level of highway system. In this paper, the Dematel method is applied to identify the vulnerability priorities of important factors, and a new assessment method for highway system vulnerability is presented by considering system cascading failure. The traffic allocation and reallocation are then optimized under user equilibrium assignment model in different scenarios. Finally, the methodology is applied to the Heilongjiang highway network and the results shows that vulnerable sections in highway networks can be determined efficiently in our proposed process. Keywords: highway traffic system; vulnerability; cascading failure 1. Introduction In China, the highway traffic system provides a comfortable and speedy transport function to all citizens, trade and industry nationwide. However, incidents, such as vehicle crashes, road construction, lane blockages, and extreme weather, can make parts of the highway traffic system impassable and thus lead to widespread cascading failure. Taking the low-temperature frost and snow disaster in southern China in 2008 as an example, highway traffic was hindered in many provinces and direct losses of up to 159.5 billion yuan and 162 lifelines were resulted [1].

With the change of the elderly's demand for pension, Kangyang has become a new way of providing for the aged. In order to study the suitability of Kangyang various cities in Heilongjiang Province, based on the relevant scholars’ research on different types of Kangyang, the basic framework of evaluation system was established by combing the four elements of ecology, humanity, people’s livelihood and medical treatment. 25 indexes were selected as evaluation indexes, and the evaluation was conducted by entropy weight - TOPSIS method. The results show that Yichun is the most suitable city for health care, Qiqihar and Suihua need to strengthen construction in all aspects, and other cities have their own advantages. Therefore, the city needs to strengthen different aspects of construction according to its own actual situation, so as to enhance the comprehensive strength of the suitability of health care. perspective of life, Kanyang should take into account the three dimensions of life: the length of life; the abundance 1 Introduction of spiritual level; the degree of freedom of life, which is Since the 1990s, China’s aging problem has been the international index system used to describe the quality increasing, and the related pension issues have been of life. The core function of Kangyang is to maximize the constantly explored and discussed. By the end of 2019, length, abundance and freedom of life.Kangyang originated in Germany and prevail in the United States, there are 253.88 million people aged 60 and above, [1] accounting for 18.1% of the total population in China.

  • Natural City Growth in the People's
    Natural City Growth in the People’s Republic of China Peter H. Egger,Gabriel Loumeau, and Nicole Püschel∗ This paper analyzes the growth of Metropolitan Statistical Areas in the PRC between 1992 and 2013 by focusing on the night-light radiance—a measure of economic activity—of connected subcity places that we refer to as a natural city. This paper documents the rapid growth of natural cities in the PRC between 1992 and 2009 that was followed by a slight reduction in the size of some natural cities between 2010 and 2013 in the aftermath of the recent global financial crisis. Institutional factors—such as the location of places near Special Economic Zones, the ramifications of legal migration from rural to urban areas following reforms to the hukou (household registration) system, and infrastructure accessibility—are found to be important drivers of the integration of peripheral places into natural cities.

Introduction With the increase in global population, the change in urbanization rates around the world is a dynamic phenomenon. While in 1994 only about 30% of the world’s population lived in cities, as defined by national statistical offices, about 54% did in 2014.1 In the People’s Republic of China (PRC), which has been among the most dynamic economies in the world over the last quarter of a century, almost 25% of the population has moved to urban areas during the past 2 decades. The PRC’s National New-Type Urbanization Plan, 2014–2020 targets an urbanization rate of 60% by 2020.
