Analysis of Climate Characteristics of Sunshine Hours in Dalian City in Recent 59 Years

[Objective] The aim was to analyze the changes characteristics of sunshine hours of Dalian City. [Method] Based on the data of sunshine hours of Dalian City during 1951 to 2009 and by dint of linear estimation and accumulation anomaly, the change characteristics of decade, annual, seasonal, monthly sunshine hours in Dalian City were analyzed. [Result] The change characteristics of decade, annual, seasonal, monthly sunshine hours in Dalian City were in a decrease trend since recent 59 years. The average sunshine hour in 1950s was the maximum one. Since 21st century, the annual sunshine hour was the lowest one. Annual average sunshine hours were the highest in 1978, and lowest in 2003. There were more sunshine hours before 1989 and later less. Among the four seasons, the sunshine hours in autumn decreased fastest and slowest in spring. The monthly average sunshine hours were the most in May and least in December; the sunshine hours in each month decreased fastest in July. It showed increasing tendency only in March. [Conclusion] The study supplied scientific reference for the reasonable utilization of light energy, agricultural production structure and sustainable development of agricultural economy.

Use of QSAR and SSD methods on deriving predicted no-effect concentrations in seawater and sediment for ten individual parent-and alkyl-PAHs and a case study on the assessment of their ecological risks from the Dalian Bay, China

Parent and alkylated polycyclic aromatic hydrocarbons(alkyl-PAHs),which are a class of important toxic components of crude oil especially in the marine environment,exhibit adverse effects on aquatic life and potentially pose a human health risk.However,the lack of chronic toxicity data is one of the hindrances for alkylPAHs when assessing their ecological risks.In this study,predicted no-effect concentrations(PNECs)in seawater and marine sediment for ten parent-and alkyl-PAHs were derived by applying species sensitivity distributions(SSDs)and quantitative structure-activity relationships(QSARs).The local area,Dalian Bay,where an oil-spilled accident happened in 2010,was chosen as a case site to assess ecological risks for ten PAHs in surface seawaters and marine sediments.Their PNECs in seawater and sediment for protecting aquatic organisms in marine ecosystems were calculated and recommended in the range of 0.012-2.79μg/L and 48.2-1337 ng/g(dry weight),respectively.Overall,the derived PNECs for the studied PAHs in seawater and marine sediment were comparable to those obtained by classical methods.Risk quotient results indicate low ecological risks to ecosystems for ten parent-and alkyl-PAHs in surface seawaters and surface sediments from the Dalian Bay.These findings provide a first insight into the PNECs and ecological risks of alkyl-PAHs,emphasizing the role of the computational toxicology in ecological risk assessments.The use of QSARs has been identified as a valuable tool for preliminarily assessing ecological risks of emerging pollutants,being more predictable of real exposure scenarios for risk assessment purposes.

Clostridium Butyricum with High Yield of 1,3-Propanediol Developed by Dalian University of Technology

The Dalian University of Technology(DUT)has disclosed a strain with high yield of 1,3-propanediol coupled with a sequencial inoculation fermentation process.This strain is called Clostridium butyricum DL07,which can produce 104.78 g/L or 94.23 g/L of 1,3-propanediol,respectively,by fermenting pure glycerol or crude glycerol,respectively,to set a highest yield of 1,3-propanediol obtained via fermentation of pure/crude glycerol by using natural micoorganisms reported so far.

Precipitation Variation during the Crop Growing Season and Analysis of the Trend of Agricultural Drought and Flood in Dalian City in Recent 60 Years

[Objective] The aim was to study the precipitation changes and agricultural flood and drought degree of crops in Dalian City in recent 60 years. [Method] The monthly precipitation and average temperature data from April to October during 1951-2010 in Dalian observation station were selected. By dint of linear regression, climate tendency rate and humidity index, the growth changes and agricultural flood and drought degree of crops in recent 60 years in Dalian City were expounded from the aspects of natural precipitation tendency changes and agricultural water satisfaction degree of crops in growth period. [Result] In recent 60 years, the precipitation of crops during growth period in Dalian City had decreasing tendency. The inclination rate was -15.888 m/10 a. Precipitation decreased 95.3 mm in recent 60 years; precipitation increased a little in spring and decreased a lot in summer, then decreased in autumn. The monthly precipitation in each month distributed unevenly. Precipitation in July and August increased, taking account of 53.8% of the total precipitation during the growth period of crops. The K value of humidity index during the growth period of crops in Dalian in recent 60 years was 0.90 in general. It was light drought climate. The humidity index was decreasing. Climate developed toward drought direction; the drought occurrence frequency was 59%. It was mild drought climate in spring and autumn. The climate was generally wet in summer. Seen from the yearly means, besides of July and August, it reached mild drought degree in other months. [Conclusion] The study provided reference for the regional agricultural production, agricultural structure adjustment and drought and flood disaster prevention.
