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.

城市公园繁殖鸟类生态位与种间关系

探究城市鸟类的生态位和种间关系有助于正确认识城市鸟类的共存机制。2021年4—8月,利用样线法对广西柳州12个城市公园进行鸟类调查,采用Levins生态位宽度指数、Pianka生态位重叠度指数、Spearman秩相关性系数等分析14种繁殖鸟类的生态位特征与种间关系。结果表明:柳州城市公园暗绿绣眼鸟的生态位宽度值最高,白头鹎和鹊鸲的生态位重叠度最大,鸟类的生态位宽度与其分布的公园数量呈线性相关;鸟类群落呈显著正联结,且鸟类群落正相关物种对的比率远远高于负相关物种对的比率,支持群落的正联结结论;鸟类的生态位重叠度受物种功能距离的影响,功能距离越近的物种,生态位重叠度越大,共同出现的概率越高。研究结果为城市鸟类物种的共存提供了实证数据和新的见解,建议在城市生境中,优先保护特化物种的栖息地;增加城市公园的生境复杂性,满足不同鸟类物种的生态需求,促进城市鸟类物种的共存和生态系统服务功能的发挥。
