In recent years, urban and rural industrial parks have been constructed and widely operated. With the development of intensive agricultural production and accelerated urbanization progress, heavy metals enter rural soil through sewage irrigation, sedimentation of atmospheric soot, and landfill treatment. Heavy metals are not easily degraded and transferred by microorganisms. Restoration and renovation of heavy metal-contaminated rural soil have been difficult. Controlling measures of governing soil heavy metal pollution were proposed to analyse causes of rural soil heavy metal pollution in Hunan Province, China. Based on time series data in Hunan during 2000-2014, this study combined features and analysed causes of rural soil heavy metal pollution in Hunan. The main causes of rural soil heavy metal pollution in Hunan are long-term use of sewage irrigation, stacking of solid waste, large discharge of industrial and traffic waste gases, and great application of chemical fertilizers and pesticides. Rural soil heavy metal pollution in Hunan can be effectively controlled by (1) establishing legislative system for soil heavy metal pollution control, (2) perfecting legal institutions of soil heavy metal pollution, (3) completing supporting law-making stipulations for heavy metal pollution control, (4) optimizing accountability mechanism, and (5) innovating environmental supervisory mechanism of heavy metal pollution control. This study is of positive significance to further and sufficiently recognize causes of rural soil heavy metal pollution. This work is also important in establishing and perfecting laws and regulation system for rural soil environment and resource protection in Hunan Province.

To govern environmental pollution by mandatory means, like administrative policies plus laws and regulations, can effectively curb the blind development of resources and ensure the sustainable development of the rural environment. Taking new countryside construction in the Dongting Lake area, Hunan Province, this paper discusses main environmental pollutions and related legal situation by use of literature and logic analysis. As is revealed in the paper, environmental protection laws are already in place during the new countryside construction in the Dongting Lake area, but there is lack of relevant regulatory bodies, with unclear assignment of responsibilities, thus, the environmental pollution remains grave in this area. Given this, the paper puts forward some countermeasures and suggestions on the environmental pollution laws pertaining to the new countryside construction in the Dongting Lake area, with a view to pressing ahead with the new countryside construction in the region.

Analysis of volatile components in herbal pair Ramulus Cinnamomi-Herba Schizonepetae (RC-HS), single herb RC and HS was performed with two-dimensional gas chromatography-mass spectrometry (GC/MS) data coupled with alternative moving window factor analysis (AMWFA) and heuristic evolving latent projections (HELP). The results show that by means of these methods of two-dimensional data,50,53 and 49 volatile chemical components in essential oil of HP RC-HS, RC and HS were determined qualitatively and quantitatively, accounting for 91.87%, 86.25% and 92.86% total volume fraction of essential oil of HP RC-HS, RC and HS, respectively. There are 26 common active constituents between HP RC-HS and single herb RC, and 22 common active constituents between HP RC-HS and single herb HS. The number of volatile chemical components in RC-HS is the result of synthesis effect from the two single herbs. Analysis of the complicated system of Chinese medicine can be performed with alternative moving window factor analysis and heuristic evolving latent projections. © 2017, Central South University Press.

Water pollution in the Xiang River Basin of China is exacerbated by continuous population growth, rapid economic development, and accelerating urbanization. Abundant pollutants from various sources significantly degrade the basin/s water quality. The degradation of water quality influences the economic and social development in urban agglomeration along the basin. To analyse the current status and explore appropriate regulatory measures of water pollution in the Xiang River Basin of China, this paper discusses causes, current status and variations of water pollution in the Xiang River Basin based on the 2002-2015 statistical data of urban agglomeration and environmental pollution in the basin. Results demonstrated that the Xiang River basin is moderately polluted. The majority of the basin/s water bodies are polluted at the III-level. Approximately 70% of total pollution in the basin is contributed by III-level, IV-level, V-level, and inferior V-level pollution. Large-scale industrial wastewater drainage, extensive pesticide use, urban sewage pollution, and ineffective government control measures are the main causes of water pollution in the Xiang River basin. Water pollution in the basin has the following characteristics: 1) water pollution is becoming increasingly complicated; 2) industrial waste gas and atmospheric pollution intensify water pollution; 3) degradation of ecological and environmental functions causes abnormal self-recovery of the water body; 4) large-scale exploitation of mineral resources intensifies water pollution. Water pollution in the Xiang River basin can be effectively improved by perfecting the legal constructions of scientific decision, administrative organization, and public participation. Results in this paper can provide scientific and accurate references to understand causes and current status of water pollution in the Xiang River basin, to continuously increase the regulation level of water resource management, and to help related departments in the continuous utilization and optimal configuration of water resources in Xiang River.

Coherent control of quantum tunnelling is investigated analytically for two bosons held in a driven triple-well potential. In the high-frequency region within resonance, the non-Floquet states with slowly varying populations are constructed by the linear superposition of Floquet solutions. For the non-resonance case with appropriate reduced parameters, we obtain another set of analytical solutions and their numerical correspondences, which exhibits the selective tunnelling effect of atoms. Applying the presented analytical results, a scheme to transport two bosons from the first well to the third is suggested by adjusting the driving parameters. © 2013 IOP Publishing Ltd.

Dopamine, a sustainable and cheap raw material, was selected as the carbon and nitrogen sources to synthesize hollow nitrogen-doped carbon microspheres (HNCMS). The obtained HNCMS were used as a non-noble-metal electrocatalyst for oxygen reduction in alkaline solution and show high electrocatalytic activity, excellent long-term stability, and tolerance to crossover effect of methanol.

Linear feature detection in digital images is an important low-level operation in computer vision that has many applications. In remote sensing tasks, it can be used to extract roads, railroads, and rivers from satellite or low-resolution aerialimages, which can be used for the capture or update of data for geographic information and navigation systems. In addition, it is useful in medical imaging for the extraction of blood vessels from an X-ray angiography or the bones in the skull from a CT or MRimage. It also can be applied in horticulture for underground plant root detection in minirhizotron images.In this dissertation, a fast and automatic algorithm for linear feature extraction from images is presented. Under the assumption that linear feature is a sequence ofcontiguous pixels where the image intensity is locally maximal in the direction of thegradient, linear features are extracted as non-overlapping connected line segmentsconsisting of these contiguous pixels. © (2014) Trans Tech Publications, Switzerland.
