    Study on a Stratified Sampling Investigation Method for Resident Travel and the Sampling Rate by Fei Shi

    Published 2015-01-01
    “…The stratified sampling rate formula and the sampling rate of each layer have been derived in detail according to Probability Theory and Mathematical Statistical Methods. Finally, for the main urban area of Kunshan City in Jiangsu province, China, we discussed the reasonable values of parameters in the formulas and obtained sampling rates for travel surveys in different residential areas. …”

    Influence of Urban Development on Extreme Precipitation in Plateau Lake Basin by LI Baofen, LI Xiaopeng, CAO Yimei, JIN Zhuo

    Published 2023-01-01
    “…Studying the influence of urban development on extreme precipitation in the lake basin region is of practical significance for urban flood control and disaster reduction,forecasting and early warning capability increase and emergency response capacity building,“four pres” improvement,and risk tackling of extreme precipitation and waterlogging disasters.Taking Kunming,a city in the Yunnan Plateau Basin,as an example,this paper adopts mathematical statistical methods to analyze the effect of urban development on the extreme precipitation index in the central urban area of the lake basin,the basin edges,and peripheral hilly areas of the city.The results show that urban development exerts different degrees of influence on various extreme precipitation indexes in lake basin areas,basin edges,and peripheral hilly areas of the basin, with the strongest,weakest,and middle effects on the basin edges, hilly areas,and lake basin areas respectively.Due to topography and the urban heat island effect,urban development also causes uneven increase and decrease in the extreme precipitation index in various areas such as lake basin areas,basin edges,and hilly areas.…”
