Authors: Fu Guanjun , Xu Zhicheng 
Published: August 2020

Abstract
In the new era, China’s energy development is facing a series of new propositions. The formulation of energy strategy needs to adapt to the changes of the internal and external environments. Based on the analysis of energy strategy evolution for China and different countries in the world, this paper proposes the influence mechanism of the internal and external environments to energy development based on the driver-state-response model, and draws on the PEST model to construct a three-level evaluation index system for energy strategic environment, in which the external environment includes four first-level indicators of international environment, political environment, economic environment as well as social environment, and the internal environment includes five first-level indicators of energy resources, energy supply and demand status, energy infrastructure, energy technology and energy market environment. The index system of energy strategic environment assessment constructed in this paper can provide a reference for China’s energy strategic analysis.

Published: August 2020

Abstract
As one of the five major transportation industries, pipeline transportation is an essential energy-transportation tool. China is in an earthquake-prone area. Earthquake is a vital factor for pipeline damage. For this reason, FLAC3D numerical simulation is used to study the dynamic response of pipelines under earthquake wave loads. The dynamic response can be mastered by analyzing the changes in acceleration, velocity, and displacement. The research results show that the destruction of the underground pipeline is mainly due to the earthquake wave effect and the displacement of the surrounding rock of the pipeline. The pipeline has the effects of increasing the earthquake wave acceleration and amplifying the earthquake stress, and it also causes the loosening of the surrounding rock of the pipeline. The pipeline after the earthquake is challenging to repair quickly, and it causes more secondary earthquake disasters. The research results are of great significance for reducing the damage caused by earthquakes to pipeline transportation projects and guiding the earthquake design of underground pipelines.

Abstract
The work of comprehensive improvement for urban rivers has been put on the daily agenda. This paper introduces in detail a comprehensive treatment scheme integrating anti-pollution, treating-pollution and monitoring maintenance in views of both the perspective of technological process and the analysis of pollutant causes. The most important thing of pollution prevention is to prevent pollutants from entering the river again. Means such as low impact development technology and laying pipelines to collect wastewater for intercepting can be adopted. The most important process of pollution treatment is dredging sludge of rivers in time and repairing water body by using ecological principles. The process of monitoring and maintenance includes monitoring of water quality in real time, regular monitoring of water ecosystem, monitoring of normalized pollutants and timely cleaning of garbage and removal of various pollution sources, which could guarantee and maintain the river’s healthy state. The three steps of river improvement promote each other and form a circular relationship. According to this scheme, the comprehensive improvement for urban rivers needs the participation of government, enterprises, society and residents, which may achieve the ultimate goal of sound ecological balance of the ecosystem. In addition, this paper gives the simple operation process of river improvement and the simple idea of sludge treatment, which provides valuable reference for improving the water treatment system.

Abstract
In order to explore the application effect of excess sludge extract from sewage treatment plant in garden flower planting, the extracts prepared from excess sludge and its fertilizer efficiency were evaluated and its effects on plant height, stem diameter, flower yield and diameter and plant weight of Impatiens balsamina were studied by pot experiments, which provided reference for the resource utilization of excess sludge. The results showed that the initial solution content of amino acid in excess sludge extract was 3.6%, and the total amount of microelement was 66.46 ppm. It was fully soluble, slightly alkaline, and the harmful elements As, Cd, and Pb did not exceed the content of the standard. Although the total amount of amino acids and microelement was lower than the standards of amino acid-containing foliar fertilizers in China, it can meet the requirement of foliar fertilizer dilution in the market and can be used as amino acid foliar fertilizer after dilution. The appropriate concentration of excess sludge extract can promote the growth of Impatiens balsamina significantly, and the application effect was close to or better than some foliar fertilizer products in the market. The best concentration was 600 times diluted excess sludge extract. If the excess sludge extract is further prepared into amino acid foliar fertilizer, the effect will be better, it can be applied in garden flower planting, and can provide a new way for the resource utilization of excess sludge in sewage treatment plant.

Published: August 2020

Abstract
An overview of the impact of climate change on vegetation is presented in this paper. With the rapid development of industries and technologies around the world, the concentration of carbon dioxide and other contaminants in the atmosphere has increased significantly. CO2 is one of the main gases responsible for global warming. Data show the global mean temperature rose by 1.15 Celsius degree in 2019 compared with the period of pre-industrial average (1800-1900). Air warmed faster than sea water based on historical data. According to the existing reseach, the Northern Hemisphere is warming faster than the Southern Hemisphere, and the warming speed of the entire Arctic is the most in the world. As a result, vegetation has to adapt to the change in temperature by its phenology. Temperature stress, water stress, phenological changes, and changes in sunshine and light intensity are the main factors that impact distribution and combination of forests.

Abstract
The bioretention pond plays an important role in controlling stormwater runoff pollution. However, the removal efficiency of the traditional bioretention pond is unstable. In this study, we used NaOH (2 mol′L−1) to modify Enteromorpha prolifera biochar (BC), preparing alkali-modified biochar (KBC). We tried to study the removal capacity of biochar as a kind of bioretention filter and optimization of operating conditions of the bioretention pond. The results showed that: (1) When modified biochar was used as the filler medium, the maximum removal rate of TN, NH4
+-N, NO3
--N, NO2
--N in effluent were 59.1%, 79.0%, 54.3%, and 76.7%, respectively; In short, the average removal rate of experimental columns added with primitive biochar increased by 1%-12%. (2) The hydraulic retention time and setting of the saturation region had a clear influence on removing nitrogen from rainwater runoff in the bioretention pond. When TL=2 h, Ds=10 cm, the average removal rates of NH4
+-N, NO3
--N, NO2
--N in effluent reached 80%, 60%, and 70%, respectively.

Authors: Chang Liuyong , Cao Zhang , Xu Lijun 
Published: August 2020

Abstract
Flashback is a critical issue for premixed flame, because it can result in increased pollutant emissions and serious mechanical damage. In this study, the sound wave is used to induce velocity fluctuation which further induces the flashback. The structure of the dynamic flashback induced by sound wave in a premixed bluff-body flame is studied using a high-speed camera. The sound pressure level is fixed at 94 dB and the sound frequency is set at 10 Hz, 30 Hz and 60 Hz, respectively. The flame images show that the transient structure of flashback can be obtained clearly by the high speed camera and the structure of flashback at different sound frequency is different. This indicates that the oscillation frequency of the instable flame affects the structure of flashback seriously.
