| 1 | Microscopic and Fractal Characterization of Organic Matter within Lacustrine Shale Reservoirs in the First Member of Cretaceous Qingshankou Formation,Songliao Basin,Northeast China显示文摘Understanding the occurrences of different fractions of organic matter in shale reservoirs is very important for the evaluation of shale oil.Lacustrine organic-rich shale samples from the first member of the Cretaceous Qingshankou Formation in the Songliao Basin were analyzed with confocal laser scanning microscopy(CLSM)and fluorescence spectral analysis.The results show that the occurrences of different organic components are related to the fabric of samples and vary with depth.The bulk content of light components is significantly higher than heavy components and exhibits a positive relationship with quartz and feldspar contents.Both light and heavy components are distributed parallel with the lamination in microscopic view in laminated samples,and randomly in massive samples.The maximum radius of light components in most of the samples is larger than 20μm,while it is smaller for heavy components,indicating the micro fractionation from clay/organic lamina to quartz/feldspar lamina.The depth of enrichment of light components corresponds to the oil maturity of organic matter.Both the distribution of light and heavy components fits the same fractal model,with fractal dimensions ranging between 2.2 and 2.5.The CLSM results confirm that it can be a reliable tool for the'sweet spot'exploration. | Bo Liu Meng Yan Xianda Sun Yunfeng Bai Longhui Bai Xiaofei Fu | 2020 | Journal of Earth Science2020，31，6： | 2 |
| 2 | Study on Prediction of the First Flowering Date of Osmanthus fragrans显示文摘[Objective]The study aimed to forecast the first flowering date of Osmanthus fragrans. [Method] Based on the data about flowering stage of O. fragrans in Guilin City from 1999-2012,the correlation between meteorological factors and the first flowering date of O. fragrans was analyzed,and a forecast model for the first flowering date of O. fragrans was established. [Result] Among meteorological factors,precipitation, humidity,temperature and sunshine hours could obviously affect the first flowering date of O. fragrans,especially humidity in August,temperature and sunshine hours in September. The forecast model could exactly forecast the first flowering date in the partial early or too late year,and the average error of date was 6 days. The factors influencing the first flowering date of O. fragrans are complex,and there is an artificial error in record data of the flowering stage,so using a single model to forecast the first flowering date have some disadvantages. When forecasting the first flowering date,we should consider all influencing factors to get a good forecast result. [Conclusion]The research could provide a new method to forecast the first flowering date of O. fragrans. | Lihong Yao Cunzhen Wang Xianda Bai Yaxin Zhang | 2013 | Meteorological and Environmental Research2013，4，5： | 1 |

| 4 | Analysis on the Impact of Mountain Climate on Tourism Development of Ziyuan County,Guangxi显示文摘Ziyuan County is in the northeast mountainous area of Guangxi,with rich tourism resources. The research on tourism climate resources of Ziyuan County could provide reference for rational development of mountain tourism in the county. Through on-the-spot investigation,the local tourism and climate data were collected,and the evolution of climate data was analyzed,and the influence of climate on tourism development was studied. It can see snow in winter of Ziyuan County,and there is not high temperature in summer,where is the best place for summer vacation.Due to typical Danxia landform,beautiful mountain ecology and comfortable climate condition,Ziyuan has become the preferred leisure vacation destination of Guilin. It should rationally utilize meteorological service information to effectively avoid the meteorological disasters,and use the climate resource advantage of mountainous area to develop Ziyuan County's tourism. | Huang Ziqin Liu Dongzhang Bai Xianda | 2017 | Meteorological and Environmental Research2017，8，3： | 0 |
| 5 | Analysis on Meteorological Conditions of Winter Cold Injury of Sugar Orange Industry in Guilin显示文摘Yield and quality of sugar orange are closely related to meteorological conditions,especially the low temperature and cold injury in mature period of fruit. To study the influence of winter cold injury on sugar orange industry of Guilin,the chilling injury weather in each county of Guilin planting sugar orange is analyzed,and the disastrous cold weather and its defense measures are studied. Frost,freezing and cold wave happen in Guilin winter sometimes,and the disastrous weather could seriously harm maturing sugar orange or that in the tree,causing peel coke,dehiscent fruit,fruit drop and quality decline. It can effectively reduce the loss by chilling injury and guarantee excellent quantity and high yield of sugar orange by timely understanding weather change information,scientifically managing water and fertilizer,and doing film cover well. | Liao Rongshun Wu Xiulian Li Zhongbo Wang Ling Su Hangzhou Bai Xianda | 2017 | Meteorological and Environmental Research2017，8，3： | 0 |
| 6 | Research on Influence of Guilin Topography on Haze显示文摘This paper analyzed space-time distribution features of haze at different topographical representative stations using haze days observation data of 50 years in different meteorological observatories of Guilin to study the topography influence on haze. Different topographical representative stations were classified into four types of mountain,hill,river and city. Mountain stations were classified into two types,surrounded by mountains and faced with mountains on two sides. Under parallel comparison method,change features of wind direction,wind speed,temperature and haze days at different meteorological observatories were analyzed to investigate the topography influence on haze with pollution increase factors excluded. The study found that the city station had the biggest haze occurrence rate,followed by the mountain station surrounded by the mountains,and the river station had the smallest haze occurrence rate. Urban heat island wind can easily cause urban pollutants concentration around the city center,and the terrain blocking to the wind is not conducive to the spread of pollutants,but the water vapor over the river can reduce the haze. | Long Fengxiang Bai Xianda Zhang Yulin | 2017 | Meteorological and Environmental Research2017，8，4： | 0 |
| 7 | Study on the Features and Risk Assessment of Drought in Guilin显示文摘Based on the precipitation data of all counties in Guilin from 1957 to 2010, the analysis has been made on the features of spatial and temporal distribution, the probability of occurrence and the periodic change of drought in Guilin.
