摘要： In Liaoning Province,there are 30-plus ski resorts and more than 100 ice&snow theme parks covering all the 14 cities of the province.The people can experience the high speed and excitement of skiing as much as they like,while enjoying the in finite fun of ice&snow games including skating,ice gyro,bumper car on ice,ice slide,sleigh,and interesting sports such as ice dragon boat,ice spike crossing,iceboating,etc.

摘要： Based on the monthly precipitation data in Fuxin from 1951 to 2019,the M-K and Pettitt mutation test,Morlet wavelet analysis,CWT,XWT and WTC methods were used to study the correlation between precipitation and sunspots in Fuxin in the past 69 years.The results show that from 1951 to 2019,only the spring precipitation in Fuxin showed an upward trend,and annual precipitation,the precipitation in the other three seasons and the annual number of sunspots all showed a relatively obvious downward trend.The first main cycles of annual precipitation,the annual number of sunspots,spring,summer,autumn and winter precipitation were quasi-28,quasi-16,quasi-51,quasi-51,quasi-27 and quasi-11 years,respectively.Annual precipitation,the annual number of sunspots,spring,summer,autumn and winter precipitation changed suddenly in 1980,2005,2005,1980,1992 and 1980,respectively.Both annual precipitation and seasonal precipitation had a relatively obvious resonance cycle of 5-15 years with sunspots,indicating that there was a good correlation between the annual number of sunspots and annual precipitation on an interannual scale.

摘要： [Objectives]To study the temporal and spatial variation of SOC content in cultivated land in black soil region in Liaoning Province.[Methods]Through the evaluation and analysis of the research data of this project and the data of the second national soil census,and using GIS technology,this paper studied the temporal and spatial variation characteristics of SOC in the black soil region of Liaoning Province,and provided a basis for improving cultivated land carbon storage and soil organic matter content.[Results]Since 1980,the SOC content in cultivated land in the black soil region in Liaoning Province has generally declined,and the spatial distribution difference has gradually decreased.From 1980 to 2018,the homogeneity of SOC distribution weakened,and the variation in a small range strengthened.The SOC content generally showed the characteristics of increase and decrease,and the changes in the area were scattered.[Conclusions]This study is of great significance to the sustainable utilization of land resources.

摘要： BACKGROUND Coronavirus disease 2019(COVID-19)has spread rapidly to multiple countries through its infectious agent severe acute respiratory syndrome coronavirus 2.The severity,atypical clinical presentation,and lack of specific anti-viral treatments have posed a challenge for the diagnosis and treatment of COVID-19.Understanding the epidemiological and clinical characteristics of COVID-19 cases in different geographical areas is essential to improve the prognosis of COVID-19 patients and slow the spread of the disease.AIM To investigate the epidemiological and clinical characteristics and main therapeutic strategy for confirmed COVID-19 patients hospitalized in Liaoning Province,China.METHODS Adult patients(n=65)with confirmed COVID-19 were enrolled in this retrospective study from January 20 to February 29,2020 in Liaoning Province,China.Pharyngeal swabs and sputum specimens were collected from the patients for the detection of severe acute respiratory syndrome coronavirus 2 nucleic acid.Patient demographic information and clinical data were collected from the medical records.Based on the severity of COVID-19,the patients were divided into nonsevere and severe groups. All patients were followed until March 20,2020.RESULTSThe mean age of 65 COVID-19 patients was 45.5 ± 14.4 years, 56.9% were men,and 24.6% were severe cases. During the 14 d before symptom onset, 25 (38.5%)patients lived or stayed in Wuhan, whereas 8 (12.3%) had no clear history ofexposure. Twenty-nine (44.6%) patients had at least one comorbidity;hypertension and diabetes were the most common comorbidities. Compared withnonsevere patients, severe patients had significantly lower lymphocyte counts[median value 1.3 × 109/L (interquartile range 0.9-1.95) vs 0.82 × 109/L (0.44-1.08),P < 0.001], elevated levels of lactate dehydrogenase [450 U/L (386-476) vs 707 U/L(592-980), P < 0.001] and C-reactive protein [6.1 mg/L (1.5-7.2) vs 52 mg/L (12.7-100.8), P < 0.001], and a prolonged median duration of viral shedding [19.5 d (16-21) vs 23.5 d (19.6-30.3), P = 0.001]. The overall median viral shedding time was19.5 d, and the longest was 53 d. Severe patients were more frequently treatedwith lopinavir/ritonavir, antibiotics, glucocorticoid therapy, immunoglobulin,thymosin, and oxygen support. All patients were discharged following treatmentin quarantine.CONCLUSIONOur findings may facilitate the identification of severe cases and inform clinicaltreatment and quarantine decisions regarding COVID-19.

摘要： Student volunteers from Dalian Ocean University push a tricycle loaded with daily necessities for delivery to dormitories of the university in Dalian, northeast China’s Liaoning Province, on January 6.On December 21, 2020, the university decided to close the campus in response to the resurgence of COVID-19.

摘要： The Lower Cretaceous Jiufotang Formation in western Liaoning is the most important fossil production horizon of the Jehol Biota, which is widely distributed in the Mesozoic basins of western Liaoning. Due to the influence of historical data, previous scholars believed that there was no volcanic activity in the Jiufotang Formation in western Liaoning. In a field investigation in western Liaoning, the authors discovered basalt and andesite in the Hujiayingzi bed. In addition, a conformable boundary was found between the Yixian and the Jiufotang formations. It indicates that both the Jiufotang Formation and the Yixian Formation are strata containing volcanic-sedimentary rocks, only differing in strength of volcanic activity.

摘要： Liaoning Province,uniquely endowed with magnesite resources,is the most concentrated area of magnesite reserves in China.The magnesite resources in Liaoning Province mainly distribute in Haicheng,Dashiqiao,Xiuyan,Fengcheng,Kuandian,Fushun areas with reserves of 2.5 billion tons,accounting for 85.8%of China,s reserves and 20%of the global reserves.Affected by the safe production and environmental protection management of mining enterprises and processing enterprises,in 2017,7.056 million tons of magnesite was mined in Liaoning Province,down by 58.1%year-on-year(YOY),as shown in Fig.1;11.511 million tons of magnesia refractory products were produced,down by 16.7%YOY.Due to the shutdown tide,there were no official statistics for year 2018.
