Study on Design Rainstorm Profile in Liuzhou City Based on Pilgrim &Cordery Method

Liuzhou City is located in Guangxi Zhuang Autonomous Region of China. It has a warm and rainy climate and belongs to the middle subtropical monsoon climate. It is a rainstorm and flood-prone area. The work of flood drainage and waterlogging prevention is very important. The “minute to minute” rainfall process data of Liuzhou National Meteorological Observation Station from 1975 to 2014 and the Pilgrim & Cordery method were used to estimate the short-time design rainstorm profile of Liuzhou City, and the profiles of the rainfall lasting for 30, 60, 90, 120, 150, and 180 min were obtained. The research shows that the same rain duration and different recurrence period conditions are consistent with the rainstorm profile. The rainfall duration of 30, 60, 90, 120, and 180 min generally shows single-peak rainstorm profile, and the rainfall duration of 150 min shows double-peak rainstorm profile. Most peaks of each short-time design rainstorm profile are at or ahead of the 1/3 part of the entire rainfall process. During the same recurrence period, the rainfall in peak period fluctuated with the increase of the duration, and the intensity of rainfall increased with the prolonging of the recurrence period.

Study on Revision and Compilation of Rainstorm Intensity Formula in Liuzhou City and County

Rainstorm intensity formula,main basis of solving urban waterlogging,is the basis of scientifically and rationally making urban drainage professional planning and drainage engineering design. In this paper,compilation of rainstorm intensity formula in Luzhai County was taken as the case,revision and compilation techniques and research methods of rainstorm intensity formulas in municipal district and administrated county of Liuzhou were introduced. According to the Design Specification for Outdoor Drainage（ GB 50014-2006,2016） and the Technical Guidelines for Establishment of Intensity-Duration-Frequency Curve Design Rainstorm Profile,historical rainfall data at Luzhai National Weather Station were sampled by using annual maximum method,and sampling time was from1980 to 2016. The period with the maximum rainfall was divided into 11 time intervals： 5,10,15,20,30,45,60,90,120,150 and 180 min. Fitting adjust of rainstorm sample data was conducted by using Pearson-III distribution curve,rainstorm intensity formula was fitted by the least square method,and calculation accuracy test corresponded with the requirement of Design Specification for Outdoor Drainage（ GB 50014-2006,2016）. Conclusions and suggestions were as below： firstly,rainstorm intensity formula was compiled and calculated according to the recommended methods of the Design Specification for Outdoor Drainage（ GB 50014-2006,2016） and the Technical Guidelines for Establishment of Intensity-Duration-Frequency Curve Design Rainstorm Profile,calculation process was normative,and calculation result error met the requirement of the specification. Secondly,sampling by annual maximum method was more suitable for the expression of periodic hydrometeorological law by taking year as reappearance period,and could cause better randomness and independence of statistical sample,and the method was scientific and reliable. Thirdly,rainstorm intensity formula compiled by taking rainfall data in national weather stations of Liuzhou and its administrated counties as the sample could be used in the scope of the local jurisdiction.

Study on Design Rainstorm Profile in Liuzhou City：Chicago Method

The design rainstorm profile is the basis of scientifically and rationally planning and designing urban drainage system, which can provide scientific theoretical basis and accurate design parameters for municipal construction, water and planning departments. In this paper, the minute-minute rainfall process data at Liuzhou National Meteorological Observation Station from 1975 to 2014 were used. Chicago method was used to analyze and study design rainstorm profile in urban district of Liuzhou, and the profiles of the rainfalls lasting for 30 , 60 , 90, 120, 150, and 180 min were obtained. The results showed that the design rainstorm profile with the same duration in each reappearance period was consistent in Liuzhou, and short-time rainfall profile roughly showed single-peak shape. The peak of each short-time design rainstorm profile was almost in 1/3 part of the whole rainfall process, and the intensity of rainfall increased with the prolonging of the recurrence period. The rainfall intensity at the peak in the same reproducing period showed 11 decrease - increase -decrease＂ as the duration increased, and the peak value of rainfall lasting for 120 min was the maximum.

Social Security of Land-losing Farmers in Urban Demolition——A Case of Hedong Village, Chengzhong District,Liuzhou City

Based on the survey of peasants from 40 households who are chosen at random and have lost their land in the Hedong Village of Liuzhou, the status quo of land expropriation and social security of land-losing peasants are expounded. The social security problems of peasants in urban demolition and peasantsh desperate demands are analyzed as follows. For example, the Main problems after the peasants losing their lands cover the substandard of resettlement, which can not maintain the former living standard; the source of income has changed and the relevant security mechanism has not been established; the peasants who have lost their land are in desperate need of more stable jobs and stable income. In view of the current situation, the countermeasures and suggestions for establishing social security mechanism for peasants who have lost their land are put forward. The measures cover establishing the subsistence allowances for land-losing peasants; establishing the guarantee system for aged people; building medical care system; providing employment and training opportunity, trying to increase the channels of employment for farmers and fostering the employment security system for peasants who have lost their land.

目的 分析广西柳州市某三甲综合医院在疾病诊断相关分组(diagnosisrelatedgroups,DRG)付费下执行中医优势病种按病种点数法付费的实践情况,为优化医院付费管理和完善付费改革提供建议。方法 以2022年7月—2023年12月柳州市某三甲综合医院实行中医优势病种按病种点数法付费的病例及相同诊断按DRG付费的病例为样本,采用SPSS24.0统计学软件进行分析和描述统计。比较柳州市某三甲综合医院中医优势病种点数法付费申报及通过例数、中医治疗腰椎间盘突出2种付费方式均次费用和住院天数、中医治疗腰椎间盘突出2种付费方式结算盈亏。结果 2022年7月—2023年12月每月中医优势病种付费的申报例数、申报病种、申报科室和成功结算病例数呈递增趋势;筛选中医治疗“腰椎间盘突出”的非手术病例按DRG付费和中医优势病种付费分2组对比分析,2组均次费用比较,差异无统计学意义(P>0.05);而中医优势病种付费组的住院天数为(8.81±2.72)d,结余例数占比为60.42%,高于DRG付费中医治疗组的(6.77±2.86)d、34.62%(P<0.05)。结论 某三甲综合医院应充分利用中医药服务支付方式改革的机遇,发展中医科室及中医治疗项目,做好中医人才培养,顺应多元化付费方式改革。建议医保部门完善中医优势病种遴选和准入标准,强化信息建设,及时反馈中医优势病种付费数据,进一步提高中医优势病种付费的精细化管理。

我国中医医保支付方式改革的典型模式比较研究

从比较研究视角出发,对国内三种中医医保支付方式改革的典型模式进行分析,为后续优化中医医保支付方式提供依据与参考。南京市推行中医按疾病诊断相关分组(Diagnosis Related Groups,DRG)付费,柳州市推行中医优势病种按疗效价值付费,杭州市推行基于“中治率”的中医医疗服务支付倾斜政策。三地先行先试,做法各异,形成不同的中医医保支付改革模式,在促进中医药事业发展中发挥先锋模范作用。通过比较得出,中医医保支付方式改革需要抓住中医“优势”本质,结合各地实际推出体现中医元素、多路径结合的付费方式,促进中医药事业发展和中医医院高质量发展。

柳宗元柳州事迹的历史叙述——以韩愈为中心

柳宗元去世后,韩愈先后写了3篇纪念文章,对柳宗元柳州事迹进行了相关描述,涉及三个方面:一是柳宗元为官柳州时期的政绩;二是“死后为神”,柳州民众为其建庙祭祀;三是作为著名文学家来指导后学,对岭南文化的发展作出了贡献。后世文人对柳宗元在柳州事迹的叙述有所增加,但仍以韩愈的叙述为基础。韩愈对柳宗元柳州事迹的历史叙述,在一定程度上确立了柳宗元的历史地位。

柳州螺蛳粉辣度分级研究

参照GB/T 21266—2007检测柳州螺蛳粉汤料、辣椒油及二者混合后的辣椒素类物质含量,结果表明辣椒素类物质基本存在于辣椒油中,汤料中辣椒素类物质含量较低。为贴近GB/T 21265—2007,优化了使用乙醇作为提取溶剂检测辣椒油中辣椒素类物质的方法;比较直接品尝、热水混合、螺蛳粉混合辣椒油3种条件下的感官辣度,并使用电子舌区分不同辣度样品,结果表明和螺蛳粉共同品尝才能体现实际辣感;通过计算食用螺蛳粉时摄入的油量,结合辣椒素类物质检测结果,并对比其他辣度分级,得到螺蛳粉辣度分级方法:随螺蛳粉单次摄入辣椒素类物质0.00009 g、0.00015~0.00020 g、0.00018~0.00025 g及以上,可分别获得微辣、中辣、特辣的感官;依此,结合油量,可算得辣椒素类物质含量-油量-辣感的组合,为螺蛳粉标准化生产、消费者选购及其他样品的感官评价提供参考。
