Characteristic Analysis of the Temperature Variation in Baoji City in Past 52 Years

The characteristics of the temperature variation in Baoji City were analyzed with the temperature data from 1952 to 2003.The results showed that the value of annual average temperature and seasonal average temperature wavily rose before 1980 and obviously ascended after 1980.During the period of last 52 years,there was a process of ascent-descent-ascent in summer seasonal temperature variation.While in autumn and winter,the temperature decreased at first and then increased.The steady ascent of the temperature in summer season had a great contribution to the increment of its average temperature.The type of the variation trend in the average temperature in Baoji in recent 52 years was verified according to the results.

Problems of Land Use during Urbanization of Western China: A Case Study in Baoji City,Shaanxi Province

Baoji City develops much faster recently, and much progress has made on urbanization. On the other hand, urbanization has been closely linked to use of land resources, for city expansion relies on lands. According to the 6th demographic census of Baoji and land survey in 2009, the research analyzed problems in urbanization of Baoji and concluded that urbanization proceeds well, as well as land intensified use. Still, the problems can never be ignored, such as poor land quality,decreasing farmland, low land use ratio and intensive use degree, slow optimization process of land use structure, more limiting factors of land development and use,heavier eco-environment protection tasks. Additionally, the research proposed specific countermeasures based on status quo of land use.

Spatial Identification of Urban Ecological Function on the North Slope of Qinling Mountains Based on Ecological Sensitivity—A Case Study in Baoji, China

Since the 17th National Congress of the Communist Party of China, ecological civilization has been the key construction goal in China, which has a profound impact on the process of urbanization. In recent years, with the rapid development of urbanization and unreasonable land development and utilization, the ecological environment has deteriorated sharply, and the stability of ecological environment has always been a difficult problem in the process of regional development. The spatial division of urban ecological function can be divided into different types of spatial utilization according to the fragile state of ecological environment, which not only guarantees urban construction but also maintains the ecological environment health, and has great economic benefits and ecological value in formulating regional development strategies and ecological protection. In this paper, from four perspectives of “land, water, human and forest”, eight factors affecting ecological sensitivity were selected, and GIS spatial superposition method was used to conduct qualitative and quantitative analysis on the ecological sensitivity of Baoji City, and the evaluation results of single factor ecological sensitivity and comprehensive ecological sensitivity were obtained. The areas with different ecological sensitivity are divided into extremely sensitive areas, highly sensitive areas, moderately sensitive areas, slightly sensitive areas and non-sensitive areas. The research shows that the proportion of extreme, high, moderate, mild and insensitive areas in Baoji City is 7.32%, 10.57%, 22.25%, 42.91% and 16.95% respectively. Finally, the areas with different sensitivity grades are identified as three types of urban ecological function areas: ecological conservation area, ecological coordinated moderate utilization area and ecological suitable construction area, so as to provide scientific theoretical basis for urban construction and land use optimization in Baoji City.

宝鸡地区人群骨密度分析

目的研究宝鸡地区人群骨密度分布现状和特征,评估骨质疏松性骨折风险,为临床干预、健康指导提供参考。方法回顾性分析2021年6月至2023年2月在我院行双能X线吸收检测法(DXA)的5830例机会性筛查人群骨密度检查资料。比较不同性别人群各部位的骨密度差异;分析不同性别人群各部位骨密度随年龄变化趋势;比较宝鸡地区20~80岁不同性别人群各部位骨密度峰值与国内大样本研究结果;分析体质指数(BMI)与骨密度的相关性。结果男性各部位骨密度基本高于同龄段女性。不同性别人群基本表现为腰椎骨密度最高,全髋骨密度次之,股骨颈骨密度最低。随着年龄的增长,不同性别人群骨密度变化趋势显著不同,男性骨密度丢失缓慢,女性骨密度丢失开始时间更早,丢失速度更快且呈现加速趋势。结论宝鸡地区人群骨密度在不同性别、不同部位的分布特征与国内大部分地区人群相似,女性骨质流失更早更快,导致女性骨质疏松症发病率更高、发生时间更早。

Spatio-temporal evolution of drought and flood disaster chains in Baoji area from 1368 to 1911

Based on the collation and statistical analysis of flood and drought information in Baoji area from 1368 to 1911, and in the context of climate change, we investigated the spatio-temporal evolution characteristics of drought and flood disaster chains in this area during the Ming and Qing dynasties using the methods of moving average, cumulative anomaly and wavelet analysis. The results are as follows:(1) We found a total of 297 drought and flood events from 1368 to 1911 in Baoji. Among these events, droughts and floods occurred separately 191 and 106 times, which accounted for 64.31% and 35.69% of the total events, respectively.(2) We observed distinct characteristics of flood and drought events in Baoji in different phases. The climate was relatively dry from 1368 to 1644. A fluctuant climate phase with both floods and droughts occurred from 1645 to 1804. The climate was relatively wet from 1805 to 1911. Moreover, we observed a pattern of alternating dry and wet periods from 1368 to 1911. In addition, 3 oscillation periods of drought and flood events occurred around 70 a, 110 a and 170 a, which corresponded to sunspot cycles.(3) We also observed an obvious spatial difference in drought and flood events in Baoji. The northern and eastern parts of Weihe River basin were regions with both frequent droughts and floods.(4) The sequential appearance of drought and flood disaster chains in Baoji from 1368 to 1911 was in response to global climate change. Since the 1760s, global climatic deterioration has frequently led to extreme drought and flood events.
