基于Theil指数的河南省旅游区入境旅游经济发展差异研究

以2011—2015年河南省入境旅游外汇收入作为衡量指标,采用标准差、变异系数和泰尔指数等方法探讨河南省五大旅游区之间入境旅游经济的区域差异性以及空间集聚.研究表明:河南省入境旅游虽获得了较快发展,但地市间的绝对差异和相对差异都呈持续增大的态势;五大旅游区在地带间差异和地带内差异上也呈现着各自不同的特征,区域差异明显;此外河南省入境旅游向热点旅游地集聚的态势较为显著,五大旅游区分离系数减小,核心城市旅游区聚集态势显著,空间集聚增强,而且洛阳市、郑州市、焦作市、开封市等地成为入境旅游经济的增长极.五大旅游区入境旅游经济的差异性主要与当地旅游资源、交通区位和旅游设施有密切的关系.     

面向出口匝道拥挤的快速路速度协调控制模型

为缓解快速路出口匝道的交通拥挤,提出了从主线上进行速度协调控制的方法,在现有基于断面的速度协调控制模型的基础上,通过对入口匝道、出口匝道等的修正构建了面向出口匝道的基于车道的速度协调控制模型,描述和预测每个车道的交通流状态,以路网行程时间最短、总通过量最大为优化目标,对每个车道分别进行最佳速度引导.并搭建仿真系统,分析不同交通需求情形下,基于车道和基于断面的速度协调控制策略的实施效果.结果表明:速度协调控制策略更加适用于中高密度,当交通需求量较高时,相比于无控制策略,基于车道和基于断面的速度协调控制模型均能降低车辆平均延误,且在大多数情形下,基于车道的速度协调控制模型效果优于基于断面的控制模型,对缓解交通拥堵、提高交通安全具有一定助益.

Responses of desertification to variations in wind activity over the past five decades in arid and semiarid areas in China

There have been significant variations in wind activity over the past five decades in arid and semiarid areas in China. High wind activity occurred from the 1960s to the 1970s, but wind activity has decreased continuously from the 1980s to the present; as a result, the potential sand transport during the latter period was only 20%-50% of the values during the 1960s and 1970s. Phases of high wind activity were highly consistent with the trends in desertification over the past five decades in arid and semiarid areas in China, but spring precipitation was also a significant factor： rapid desertification during the 1960s and 1970s was due to high wind activity, generally combining with low spring precipitation; subsequent rehabilitation since the 1980s has resulted from the combined effects of low wind activity and higher spring precipitation. Therefore, although modern desertification and rehabilitation processes are being more or less affected by human activities, both processes appear to be more strongly controlled by climate change.     

Characteristics of paleoflood deposits archived in unit T0403 of Yuxi Site in the Three Gorges reservoir areas,China

Based on the detailed analyses,multi-proxies such as AMS 14 C dating,grain size,component and morphology of heavy minerals,micromorphology of zircon,magnetic susceptibility,Rb/Sr and Hg content are used to research the paleoflood sediments archived in the Yuxi Site.The research indicates that, since 7.6 kaBP,at least 16 times of paleoflood with water level above Wusong Elevation 147.024 m(a.s.l.) left deposits in the Neolithic layers of unit T0403 from the Yuxi Site.The results are induced from the following aspects:(1)The plaeoflood sediments take on great similarities with modern flood sediments in the Yuxi Site and Zhongba Site in probability cumulative curves which mainly show a pattern of 3 segments in fluvial pattern.(2)There is some resemblance between the heavy mineral components and the zircon shape characteristics of paleoflood deposits and those of modern flood deposits.(3) Magnetic susceptibility values(40.44―70.10SI)are lower than those of sediments from cultural layers (59.59―188.68SI).(4)Hg values(290.71―742.51 ng/g)are lower than those of sediments from cultural layers(344.16―10518.17 ng/g).(5)Rb/Sr values are higher than those of sediments from cultural layers, while those of the 4th,5th,6th,7th,8th cultural layers are high,which shows that they are inundated by paleoflood.The reason for many flood deposits existing is related to the site situated on the first terrace where the Yuxi River joins with the Yangtze River.As there are some similarities between the plaeoflood sediments and those of the Zhongba Site,it is feasible to confirm the existence of paleoflood sediments based on the above points.

Simulation of historical and projected climate change in arid and semiarid areas by CMIP5 models

Based on Climatic Research Unit Time Series3.1 temperature and Global Precipitation Climatology Center full data reanalysis version 6 precipitation data,the abilities of climate models from the fifth phase of the Coupled Model Intercomparison Project to simulate climate changes over arid and semiarid areas were assessed.Simulations of future climate changes under different representative concentration pathways(RCPs)were also examined.The key findings were that most of the models are able to capture the dominant features of the spatiotemporal changes in temperature,especially the geographic distribution,during the past 60 years,both globally as well as over arid and semiarid areas.In addition,the models can reproduce the observed warming trends,but with magnitudes generally less than the observations of around0.1–0.3°C/50a.Compared to temperature,the models perform worse in simulating the annual evolution of observed precipitation,underestimating both the variability and tendency,and there is a huge spread among the models in terms of their simulated precipitation results.The multimodel ensemble mean is overall superior to any individual model in reproducing the observed climate changes.In terms of future climate change,an ongoing warming projected by the multi-model ensemble over arid and semiarid areas can clearly be seen under different RCPs,especially under the high emissions scenario(RCP8.5),which is twice that of the moderate scenario(RCP4.5).Unlike the increasing temperature,precipitation changes vary across areas and are more significant under high-emission RCPs,with more precipitation over wet areas but less precipitation over dry areas.In particular,northern China is projected to be one of the typical areas experiencing significantly increased temperature and precipitation in the future.     

Body weights in Han Chinese populations

The body weights of 26,954 Han Chinese adults in 67 areas （16,503 in rural areas and 10,451 in urban areas） across China were measured from 2009 to 2013. The results showed that in China, the three areas （north China, northeast China, and Jianghuai Plain） were with the greatest body weight. Northwest Hart Chinese populations were heavier. Southwestern dialect groups were at the middle level and lighter than northern Han Chinese populations, but were heavier among southern Han Chinese populations. Chinese Han who located in areas of Hangjiahu were the general level, and similar to south- western dialect groups. The mean values of body weight in Hunan Han and Fujian Han were greater than other Han groups in southern China. Gan dialect groups and Can- tonese dialect groups showed the minimum body weight value in all Chinese Han groups. Besides, the mean body weight of Hakka was heavier than Gan dialect groups and Cantonese dialect groups which were adjacent to Hakka. Body weight increases with an increase in height, bone diameter, subcutaneous fat on the limbs and trunk, chest circumference, and abdomen circumference. This study revealed that northern Han men were heavier than southern Hart men, because the former were taller and had a larger waist circumference as well as thicker subcutaneous fat on their backs. Among women, height, bone diameter of the upper limbs, chest and abdomen circumferences, and sub- cutaneous fat on the limbs and trunks of northern Hart exceeded those of rural southern Han. Consequently, body weight values of northern Han women were higher than those of southern Han women. While a significant differ- ence in these values was found between urban and rural men, no significant difference occurred between urban and rural women. Body weight was associated with age in urban and rural men only in the case of minority groups. However, there was a positive correlation between body weight and age in the majority groups of both urban and rural women. The particular composition of genes involv
