Critical Region Identification of Land Use/Land Cover based on typical ecosystem services - a case study of Beijing-Tianjin-Hebei Urban Agglomeration Yinglu Liu Peking University, Beijing, China ([email protected]) Contradictions between population, economic development, land and ecological environment occur frequently in the Beijing-Tianjin-Hebei urban agglomeration, forming a complex problem of "population - land - social economy - ecological environment" at a regional level. This study considers seven indicators, including LUCC and three typical ecosystem services, to recognize the critical regions. Through continuous experiments and adjustments of parameters, we finally determine the building methods of overlaying in a equal power, and quantificationally evaluate the land use dynamic degrees, land use extents, diversity of land use types, ecological land use ratio, carbon sequestration service, soil conservation and water production services, integrated identify critical areas of the Beijing-Tianjin-Hebei urban agglomeration. We aim at realizing the coordinated sustainable development of Beijing-Tianjin-Hebei region as soon as possible, and providing the basis for land planning. The results show that the critical regions of the Beijing- Tianjin-Hebei urban agglomeration are mainly distributed in the Yanshan and Taihang mountain regions and the surrounding towns. On the scale of county level, the first-level critical regions are mainly located in Beijing, Qinhuangdao and Chengde, and the second-level critical regions are mainly located in Chengde, Beijing, Qinhuangdao and Baoding.

UNIVERSITY OF CALIFORNIA Los Angeles The How and Why of Urban Preservation: Protecting Historic Neighborhoods in China A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Urban Planning by Jonathan Stanhope Bell 2014 © Copyright by Jonathan Stanhope Bell 2014 ABSTRACT OF THE DISSERTATION The How and Why of Preservation: Protecting Historic Neighborhoods in China by Jonathan Stanhope Bell Doctor of Philosophy in Urban Planning University of California, Los Angeles, 2014 Professor Anastasia Loukaitou-Sideris, Chair China’s urban landscape has changed rapidly since political and economic reforms were first adopted at the end of the 1970s. Redevelopment of historic city centers that characterized this change has been rampant and resulted in the loss of significant historic resources. Despite these losses, substantial historic neighborhoods survive and even thrive with some degree of integrity. This dissertation identifies the multiple social, political, and economic factors that contribute to the protection and preservation of these neighborhoods by examining neighborhoods in the cities of Beijing and Pingyao as case studies. One focus of the study is capturing the perspective of residential communities on the value of their neighborhoods and their capacity and willingness to become involved in preservation decision-making. The findings indicate the presence of a complex interplay of public and private interests overlaid by changing policy and economic limitations that are creating new opportunities for public involvement. Although the Pingyao case study represents a largely intact historic city that is also a World Heritage Site, the local ii focus on tourism has disenfranchised residents in order to focus on the perceived needs of tourists.

According to Hebei Province's actual situation, we choose 6 important variables, which reflect the regional economies level of development. By analysing the data collected, the 11 regions of Hebei Province are divided into fourtypes: the developed, the more developed, the medium and the backward. And there is large differ-ence between the four types of regions. To further promote and realize coordinated development of theHebei Province economy, we should take measures to narrow the gap including making distinctive economic zone and business circle, promoting the regional harmonious development, developing the coastal economic belt and improving the underdeveloped region self-development capabilities.

As a result, the land price in an urban area is not only aﬀected by the city’s own factors, but also by its interaction with nearby cities. Understanding the characteristics, types, and patterns of urban interaction is of critical importance in regulating the land market and promoting coordinated regional development. In this study, we integrated a gravity model with an improved Voronoi diagram model to investigate the gravitational characteristics, types of action, gravitational patterns, and problems of land market development in the Beijing-Tianjin-Hebei urban agglomeration region based on social, economic, transportation, and comprehensive land-price data from 2017. The results showed that the gravitational value of land prices for Beijing, Tianjin, Langfang, and Tangshan cities (11.24–63.35) is signiﬁcantly higher than that for other cities (0–6.09). The gravitational structures are closely connected for cities around Beijing and Tianjin, but loosely connected for peripheral cities.

Different personal and public products and services are offered by various land use types, meaning their functionality varies. Lack of judgment on temporal trends, turning points, or consideration of multi-source indicators like the ecological and air quality index leads to uncertainties in urban multifunctionality evaluation and functional orientation. In this study, the production-living-ecology land use function index system and evaluation process was improved using an entropy weight, triangle model, and coupling coordination degree. The production-living-ecology land use function (PLELUF) is defined from land use multi-functions. The Beijing-Tianjin-Hebei urban agglomeration was the representative area. The model was applied to quantify land use functions and measure spatio-temporal coordination and conflict from 1990 to 2015. Results found that the production and living functions displayed an overall upward trend and the growth rate of production function is larger, doubling from 1990 to 1995, while living function increases steadily.

49232-001: Beijing-Tianjin-Hebei Air Quality Improvement Program
Beijing–Tianjin–Hebei Air Quality Improvement–Hebei Policy Reforms Program (RRP PRC 49232) SECTOR ASSESSMENT: ENERGY Sector Road Map 1. Sector Performance, Problems, and Opportunities 1. In 2009, the People’s Republic of China (PRC) became the world’s largest energy consumer. In 2014, the PRC consumed 4.26 billion tons of standard coal equivalent (tce), which accounted for 23% of the global energy consumption. As the national government’s effort on improving energy efficiency progresses, the PRC’s energy consumption has grown at a slower rate than the overall economy since 2006. Energy intensity has improved by 13.4% in 2011– 2014 with reduction of 4.9% in 2014 compared to 2013.1 The government launched various command and control measures to address energy conservation, especially in energy intensive secondary industry. A distinctive characteristic of the PRC’s energy sector is its heavy reliance to coal. The share of coal in PRC’s primary energy consumption remained over 70% although the 2014 annual coal consumption declined for the first time in the last 2 decades by 2.9% compared to 2013.2 However the figure is much higher than the global average. The PRC government has set a target to reduce the share of coal in primary energy consumption to 62% by 2020. In parallel, although slowly, the PRC makes gradual progress in increasing the share of renewable energy generation in its energy mix. The PRC became a world leader in wind power, hydropower generation, and in solar photovoltaic manufacturing. The share of non-fossil fuel sources in the PRC’s energy consumption has increased from 7.8% in 2009 to 11.3% in 2014.
