Aiming at the problems of long monitoring time, low sensitivity and low precision of traditional methods, a nano sensor for near zero emission monitoring of sulfur hexafluoride (SF6) was proposed. The characteristics of SF6 gas were analyzed. The infrared spectrum of SF6 gas was obtained by spectral...

With the increasing demand for marine resources, the marine ecological environment system is gradually destroyed. The traditional allocation of marine resources has been unable to meet the global resource search, resulting in poor distribution uniformity of marine resources and high packet loss rate...

The reductive gas composition produced by the reburning of sludge can reduce NOx in flue gases to N2, which provides a new idea for the study of gas denitration, and at the same time makes denitration by sludge reburning become an important part of gas denitration research. However, due to the...

High-speed railway (HSR) is severely affected by precipitation disasters. There are many studies on precipitation and precipitation disasters, most of which are precipitation and analysis of disasters caused by precipitation, and few explain climate changes caused by precipitation. This paper uses...

To find out the relationship between industrial agglomeration and environmental pollution, this paper carried out empirical research on the panel data collected from 271 prefecture-level cities in China from 2004 to 2017 through a spatial panel econometric model. It reviewed the influence of...

An experimental study was carried out to investigate the energy dissipation characteristics of sea grass in a dam break flume. Dam break flows were generated in a flume. A steel ball was subjected to the dam break flow, and then climbed on a slope. Artificial sea grass was used as the energy...

In order to solve the problems of poor accuracy and long time-consuming of traditional methods in the assessment of sudden oil spill pollution from ships, this paper takes the navigation area in the South China Sea as the research object and proposes to build the assessment model of ship oil spill...

Wind erosion is mainly a phenomenon of arid and semiarid areas, and the porosity of shelterbelts is an important quantitative index for estimating windbreak structure. However, there appears to be considerable variation in the optimal degree of porosity. With the example of an oasis–desert ecotone...

Objective: To obtain the characteristics analysis results of aronia melanocarpa leaves under saline alkali stress state and improve yield and quality of aronia melanocarpa. Methods: Using hyper spectral imaging system to obtain hyper spectral images of aronia melanocarpa leaves under saline alkali...

Purpose: To research the influence of different densities of Platycladus orientalis plantation on the allocation characteristics of carbon storage in the ecosystem, the density regulation experiment on the Pinus massoniana plantation with different densities was carried out to discuss the change of...

In this study, an ecological awareness rating scale and an eco-product purchase decision-making rating scale were developed based on literature and interviews with experts. The ecological awareness variables were subdivided into three aspects: ecological knowledge, ecological emotion, and ecological...

Urban household waste causes serious pollution of the urban ecological environment. Waste separation and processing is an effective approach to reduce the ecological environment damage caused by household waste. From the perspective of the source of urban household waste separation, this paper...

Solid wastes and acid wastewater lead to the enrichment of heavy metals in the soil of mining area. Heavy metal pollution causes the decline of soil quality, ecosystem degradation, crop yield reduction, and even threatens human health. For this reason, the real-time detection method for heavy metal...

The long-term forecasting of the energy demand is an important issue of an area’s sustainable development, especially for mega cities such as Beijing. Beijing is changing its energy supply strategy to depend on energy imports from other provinces due to the city’s long-term low carbon sustainable...

In order to effectively analyze the optimal allocation mode of plant community in the process of slope ecological restoration, 15 plants were selected and 10 plant community combinations were designed. The experiment lasted for 90 days, and the optimal allocation model of plant community was...

When studying the dynamic monitoring method of forest coverage based on GIS technology, a dynamic monitoring system of forest coverage based on GIS technology was constructed, and forest coverage was dynamically monitored by means of the system. The system constructs attribute database and spatial...

Because the traditional remote sensing image monitoring method has the problem of poor ability of capturing vegetation destruction, an ecological remote sensing image method for vegetation destruction in waterfront greenway based on genetic algorithm is proposed. The vegetation index data of...

Innate immune system is the first line response against environmental changes in invertebrate. It protects the animal from environmental changes such as temperature change, PH and salinity as well as pathogens such as bacteria and viruses through different biochemical pathways. In fact, the innate...

On the Basis of Relevant Theory and Literature Research, analyze the development of forestry enterprises in northeast China, and establish the evaluation index system of the ecological situation of forestry enterprises in northeast China. Based on the composite weights of objective and subjective...

Renewable energy has two environmental externalities: one is the positive externality as an alternative to fossil energy consumption; the other is the negative externality with its production process consuming fossil energy. If the domestic renewable energy products export to foreign country with...

With the increasingly prominent problem of agricultural non-point source pollution, the process of Rural Revitalization Strategy has been seriously affected. Studying the relationship between rural human capital and agricultural non-point source pollution is helpful to form talent bonus, improve...

With the emphasis on environment and health, the environmental protection, quality and safety of historical building’s fire-retardant coating has gradually become the focus of attention. There are a lot of volatile substances in the fire-retardant coating, which volatilize continuously for a long...
