In recent years, with rapid urbanization, the underlying urban surface has changed dramatically. Various urban eco-environmental problems have emerged globally, among which the urban heat island effect has become one of the most obvious urban eco-environmental problems. In this study, Nanjing, China, was chosen as the study area. Based on Landsat 8 remote sensing image data collected in Nanjing from 2014 to 2018, land surface temperatures were retrieved, the spatiotemporal variation track and characteristics of the thermal environment pattern were systematically depicted, and the driving factors of these variations were revealed. The results show that over the past five years, the spatial pattern of the heat field in Nanjing changed from a scattered distribution in the periphery of the city to a centralized distribution in the centre of the city, and the heat island intensity increased annually. Changes in administrative divisions, changes in the layout of the transportation trunk lines, transfer of industrial centres, and ecological construction projects are important driving factors for the evolution of the land surface thermal environment patterns of these regions. These research results will provide scientific and technological support for similar cities with typical heat island effects elsewhere in the world to formulate urban development plan, and to improve the urban ecological environment.

The advantages of a quantitative assessment of the spatial and temporal variability of the boundaries and volumes of ravines using modern means and methods of aerial photography from an unmanned aerial vehicle (UAV) are substantiated, in contrast to traditional survey methods (linear method of benchmarks, tacheometric, aerial and space photography, laser scanning). The erosion zoning and mapping of linear and gully formations on the territory of the Kuitunka, Tarbagataika, and Kunaleika river basins (Selenga middle mountains) are carried out. The reanalysis data were used to assess extreme meteorological events leading to the acceleration of erosion processes. Paleontological material confirms the long duration of erosive-accumulative processes in the Nizhnyaya Bulanka depression. High-accuracy multi-temporal orthophotomaps and digital elevation models of Bulanka gully using unmanned aerial vehicles were produced. The method of quantitative estimation of gully formation rates is offered, which allows estimating with high accuracy the change of area and volume characteristics of erosive forms.

Due to interregional carbon emission (CE) transfer, the CE reduction allocation approach is crucial to the overall CE reduction effect. The prevalent allocation mode applies the production-based principle (PBP) and causes equity and efficiency losses of CE reduction. The exploration of a CE reduction policy under the consumption-based principle (CBP) is highly demanded. In this article, by studying the transfer of CEs embodied in interprovincial trade (CEs-PT) in 1997–2007 within China, we propose a CE reduction allocation approach under the CBP. We found that net CEs-PT were huge and had increased from 172.22 million tons (Mts.) to 425.94 Mts. The main transfer flow was from the resource-based provinces to the economically developed provinces, from North China to South China. Under the PBP, the transfer of CEs-PT caused serious equity and efficiency losses of CE reduction in China. Then, we propose a CE reduction allocation approach under the CBP that considers the long-term dynamic change of regional CEs. The approach can eliminate equity loss, improve CE reduction efficiency, and avoid the impact of short-term fluctuations of regional CEs. Based on this approach, we calculated China’s provincial CE reduction responsibility and found that compared with the allocation approach under the PBP, the CE reduction responsibility of most net exporters of CEs-PT decreased, while that of most net importers increased. To accomplish CE reduction efficiently and economically, we propose a CE reduction trading system. The research can provide support for CE reduction allocation policy and CE reduction trading system for China and other countries.

In nowadays, there are a large number of regions in the world facing with double pressures of ecological fragility and economic poverty. In these regions, if human choose traditional development mode to constantly exploited natural resources for developing economy, the environment will be hardly destroyed or polluted, and finally cause larger economic loss and make poverty more serious. It formed a development dilemma of environmental fragility-economic poverty vicious circle (FPVC). How to break FPVC has been the goal being pursued in the literature worldwide. In this study, we constructed a Circular-Economy-Effect-and-Policy-Simulation-System-Dynamics (CEEPS-SD) model, evaluated the ecological economic comprehensive effects and simulated the future development trends of the circular economy system (CES) which we have planned, constantly tracked and improved in Anding District of Northwest China for 16 years, that is a typical FPVC area. The evaluation and simulation results notably evidenced that the CES had four ecological economic benefits: livestock faeces pollution elimination, water saving, agricultural waste recycling, as well as energy conservation and emission reduction. Through long-term and stable operation, the CES can expand its ecological economic comprehensive benefits constantly and finally eliminate the double pressures of ecological fragility and economic poverty. This study could help large number similar FPVC areas in the world to scientifically build, manage, evaluate, simulate and optimize CES for getting rid of FPVC and achieving sustainable development, which has important theoretical significance and practical value.

The construction of China-Mongolia-Russia high-speed railways is a strategic move to promote transportation infrastructure inter-connectivity between these countries, which will accelerate the implementation of the China-Mongolia-Russia Economic Corridor. However, well-planned China-Mongolia-Russia high-speed railways demand accurately identifying construction risks, scientifically evaluating risk levels, and mapping the spatial distribution of these risks. Therefore, this study established the integrated risk evaluation model (IREM) to scientifically evaluate the economic, social, and ecological risks of China-Mongolia-Russia high-speed railway construction and determine their magnitude and spatial distribution pattern. Based on this analysis, we propose designs for the east and west China-Mongolia-Russia high-speed railways and policy suggestions to mitigate construction risks. Suggestions include developing innovative cooperation of the "high-speed railway for resources and market", strengthening communication and technology dissemination, and applying innovative engineering techniques and setting buffers; establishing collaborative prevention and control systems to mitigate the three major ecological risks in the China, Mongolia, and Russia trans-border areas; and promoting economic integration by improving strategic coordination. In summary, this study provides scientific support for designing the China-Mongolia-Russia high-speed railways minimizing construction risks.
