Aiming at China’s “2030 target,” and given the key role of industrial sectors in CO₂ emission reduction, this paper selects the path of allocating carbon emission allowance among different industrial sectors. By selecting CO₂ accumulation emissions, the industry-added value and the CO₂ emission efficiency which is calculated by the super-SBM model, a carbon intensity distribution model has been established...
Nowadays, with the depletion of fossil energy and deterioration of environmental quality, solar energy is perceived to be a renewable and clean energy. While developing rapidly all over the world, solar energy is also faced with many challenges resulting from its inherent properties. In order to reduce the impact on the grid and facilitate scheduling, it is a growing problem to build a feasible model...
The response of leaf functional traits to the shift in environmental variables can raise plant adaptiveness in a wide variety of habitats and subsequently broaden their ecological niche. This study aims to determine the differences in leaf functional traits between simple and compound leaves of Canavalia maritime to illuminate the mechanisms underlying the ecological strategy of plant species with...
This research investigates the spatial and temporal trend analysis of precipitation time series. Precise predictions of precipitation trends can play an imperative role in economic growth of a country. This study examined precipitation inconsistency for 23 stations at Dongting Lake, China, over a 52-year study period (1961-2012). Statistical, nonparametric Mann- Kendall (MK) and Spearman’s rho tests...
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...
With the effect of CO₂ emissions being the primary cause of the greenhouse effect, a selection and analysis study of driving factors of CO₂ emissions is vital to controlling growth from the source. This paper decomposes CO₂ emissions based on the logarithmic mean division index (LMDI) from three industries and residential consumption in China during the period 2000-14. A genetic algorithm-support...
The power industry, as the primary source of carbon emissions across China, should take more responsibility to effectively reduce carbon emissions. Affected by various factors, carbon emissions from the power industry show non-linear and non-stationary characteristics. To forecast carbon emissions precisely and efficiently, this paper proposes an improved particle swarm optimization (IPSO)-support...
This in-depth paper studies the issue of energy-related CO₂ emissions of China using sample data from 1980 to 2015. Due to the lack of official data, CO₂ emissions are first calculated by the recommended IPCC method. It shows that CO₂ emissions in China present an “S” type in shape. Then the Tapio decoupling index is applied to investigate the relationship between CO₂ emissions and economic growth...
The power industry is the leading source of man-made carbon emissions in China, and it is supposed to assume most of the responsibility for reducing carbon emissions. To study the decoupling status between carbon emissions and economic growth in China’s power industry, a new OECD decoupling analysis with LMDI model is employed in this paper. The results are as follows: 1. Growth and volatility are...
Rapid economic growth in the Beijing-Tianjin-Hebei region has been accompanied by a dramatic increase in carbon emissions. Therefore, a precise study of forecasting carbon emissions is important as regards curbing them. To identify the influence factors of carbon emissions and effectively predict carbon emissions under the three different GDP growth rate scenarios in the Beijing-Tianjin-Hebei thermal...
The Shiyang River Basin has been regarded as an important ecological protective area in the Hexi corridor in northwest China. Landsat TM, ETM+, and OLI images in 1986, 2000, 2006, and 2015 were selected as basic data resources, and the circle layers and fan-shaped analysis were applied to extract change information and the characteristics of land use pattern change by a set of transfer and dynamic...
This study aims to determine the functional traits and reproductive allocation (RA) strategy of the invasive plant Conyza canadensis across different invasion degrees along a latitude gradient in China. Invasion degree did not affect the functional traits and RA strategy of C. canadensis significantly. The high proportion of reproductive biomass (allocating approximately 20% of total biomass into...
Plant invasion succeeds because of such invader characteristics as fecundity and high-efficiency multiple reproduction modes. The acquisition of individual resources and the benefits of individual fitness are driven by optimum patterns of life history and trade-offs of reproductive allocation (RA) in plants, and variations in RA strategy play an key role in plant adaptation to environmental changes...
The effects of anthropogenic nitrogen (N) deposition on successful plant invaders, particularly potential effects on their leaf functional traits, have stimulated considerable research interest. This study aims to gain insights into the leaf functional traits of the controversial invader Rhus typhina in the presence of a gradient of simulated N deposition (control, 0 g L⁻¹; low N, 5 g L⁻¹; medium...
Vehicle and industrial emissions are responsible for a considerable share of urban air pollution concentrations. We conducted a comparative study in Dalian, China and Faisalabad, Pakistan to reevaluate NO₂, SO₂, and CO concentrations. Our study was conducted over the course of one year at different stations in both cities, and measured values were compared with ambient air quality standards such as...
