Taking Tangshan city, a heavy industry base in Hebei Province of China, as the research area, this study carried out a multi-scale analysis on the GHG emissions in terms of final demand, final consumption and trade balance. The main results are as follows: (1) The average embodied intensity of GHG emissions in Tangshan was 27.6 tons/10,000 CNY, of which 66.2% was caused by local inputs; (2) The secondary industry was the main source for the relatively high GHG emissions in Tangshan; (3) The GHG emissions embodied in final demand were 201.6 million tons, within which the proportion of fixed capital formation reached 59.4%; (4) As for the trade balance, Tangshan was a net exporter of embodied GHG emissions, with the total net outflows of 411.6 million tons. Depicting the GHG emission flows and sorting out the multiple GHG emission inventory would be helpful to identify the transformation pressure of resource-based heavy industry cities, which would be significant for the adjustments in industrial structures and policy optimization of energy saving and emissions reduction.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47943162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, through estimating the energy intensity per unit of labor embodied in final products in each region, this study examines whether the empirical results are consistent with the theoretical hypothesis and provides relevant explanations and industrial development suggestions. Results show that east coastal region and central region are the two main participants in interregional trade. As for the labor embodied in trade, east coastal region is the largest exporter of embodied labor, though it has the highest wage among eight regions; in contrast, north coastal and southwestern region, with relatively low wage, are the two largest importer of embodied labor. As for the energy embodied in trade, northwestern region is the largest exporter of embodied energy. Further analysis indicates that the energy intensity per unit of labor in region with relatively low GRP (such as northwestern region) is the highest, whereas those in Beijing-Tianjin Region and south coastal region (with relatively high GRP) are the lowest. By analyzing the Revealed Comparative Advantage in each region, the paper finds that the main reason for this inconsistency lies in the industrial structure in northwestern and north coastal region, which are highly dependent in primary industries. Improving the infrastructure and upgrading industrial structure are important steps for these regions to transform the extensive growth mode.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42691164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key goal is to maximizing the value of ecosystem services. This paper establishes a framework for optimizing the spatial structure and layout of the protected area based on ecosystem services. With the objective of maximizing the value of ecosystem services, it uses the CoMOLA (Constrained Multi-objective Optimization of Land-use Allocation) model for multi-objective optimization under the constraints of area and conversion rules. Taking the Yellow River’s headwaters region in the Three-River-Source (Sanjiangyuan) National Park as the study area, this paper uses the data of the year 2015 as a benchmark, and obtains the optimization results of the study area by 2035. The results show that the total value of ecosystem services of the Yellow River’s headwaters region after optimization will reach RMB [Formula: see text], with a total increase of RMB [Formula: see text] (8.47%). The land covers that contribute most to the value of ecosystem services are rivers, lakes and wetlands (51.55%), and grasslands (40.71%). Among the various types of ecosystem services, the value of provisioning services will increase by RMB [Formula: see text], regulating services by RMB [Formula: see text], supporting services by RMB [Formula: see text], and cultural services by RMB [Formula: see text]. The research results can provide a scientific basis for the spatial optimization of protected areas and the management of national parks.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47153659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a strategic decision made after deliberate consideration by the Central Government. Such goals reflect China’s responsibility as a major country in responding to global climate change, its vision of the future world development, and its commitment to green transformation. After the 18th CPC National Congress, China has undergone a fundamental change in its development philosophy. Protecting the environment is no longer regarded as a burden upon economic growth, but as a driving force for high-quality development. Emissions reduction has also changed from a task inflicted upon local governments to a goal people identify with. More than 120 countries have proposed carbon neutrality targets in different ways by now. The global consensus on carbon neutrality marks the end of the traditional industrial era and the start of a new development era. The concept of carbon neutrality redefines and reshapes the entire development paradigm. It is a self-revolution of the mode of production and life. It not only poses an unprecedented challenge but also provides a strategic opportunity for China. China is likely to lead the world in future green transformation and global climate governance.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42535954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many urban scenarios are being developed to mitigate potential risks and threats. One branch of these scenarios is built upon the concept of sustainability, for which the notion of “resilience” is of utmost importance. It is this notion of resilience that was examined in this study, based on the case of socio-ecological system features of Edremit, Van, Turkey. These features were evaluated in terms of changes that will potentially take place, and the analysis for this was performed using the Green Infrastructure Spatial Planning (GISP) method. In this approach, green infrastructure benefit criteria are mapped in the Geographic Information System (GIS) environment and various conclusions are drawn from the evaluation of these maps. The results of the study show that the green infrastructure systems of Edremit play an important role in providing a certain degree of resilience. It was, therefore, revealed as part of this study that measuring and evaluating the resilience properties of different cities is important. Also, urban policies and spatial strategies should be defined considering local characteristics and values as there is no one-size-fits-all solution in this regard.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47338917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
