The violent form of this contradiction is geological disasters. Geological disasters pose a threat to human life and property, and cause damage caused by natural or human factors, often causing casualties. The destruction process of geological disasters is usually a gradual process, showing many pre-disaster symptoms, such as local landslides, surface cracks, building deformation, tree skew, and ground sound. Evacuation can be avoided in advance according to the disaster precursors, so as to avoid casualties and achieve successful prediction. By reviewing the general situation of geological disasters in Shaanxi Province and the casualties in 2020, the difficulties in the prevention and control of geological disasters are summarized. In view of these difficulties, an on-site investigation, visit and analysis of geological disaster points and successful forecast points in Shaanxi Province in 2020 were conducted. In addition, combined with actual cases and years of work experience, the successful prediction experience of geological disasters was discussed from 8 aspects. Finally, the “Regulations on the Reward for Successful Geological Disaster Forecasting in Shaanxi Province” was revised in order to improve the successful prediction ability of geological disasters in Shaanxi Province and even the whole country, provide reference for future prevention and control of geological disasters, and effectively protect the safety of people’s lives and property.展开更多

The REE pattern in Ni ore is similar to that in Au ore and is characterized by typical enrichment in LREE and sharp negative Eu and Ce anomalies, indicating that Ni ore and Au ore were formed from the same hydrothermal solution. δ Eu and δ Ce variations reflect that Ni ore is formed at higher temperature and relative reduction environment, and Au ore at lower temperature and relative oxidation environment. The characteristics imply that the ore forming materials were derived from the ultrabasic rock and the hydrothermal solution is a post magmatic acidic solution.展开更多

文摘Objectives:Compare the differences between the intervention and control groups in changes of primary outcomes(body mass index[BMI]and waist-to-height ratio[WHtR])and secondary outcomes(nutrition knowledge of children and parents),from baseline to the 6-and 12-month follow-ups;examine the associations of changes in nutrition knowledge of children and their parents with children’s changes in BMI and WHtR.Data sources:Data collected from four schools in two poverty-stricken counties in northern Shaanxi Province in 2020‒2021.Methods:A multifaced intervention program targeted children(promoting healthy diet and nutrition education)and their parents(promoting nutrition knowledge)was conducted in the interventional group.Four schools,with two in each group,were randomly allocated to the intervention or control group,with 814 eligible children aged 7.1 to 12.8 years.The control group conducted myopia promotion.Differences in changes of BMI and WHtR between groups were compared with t-test.Mixed-effects model was used to examine the associations between changes in nutrition knowledge of children and parents with changes in children’s BMI and WHtR.Results:At the 6-month follow-up,the difference in changes in BMI between the intervention and control groups was 0.4 kg/m 2(P<0.001).At the 12-month follow-up,the difference in changes in BMI and WHtR between intervention and control groups was 0.1 kg/m^(2)(P<0.001)and 0.01 kg/m^(2)(P<0.001).In the intervention group,the nutrition knowledge awareness rate of children increased from 16.9%(69/409)at baseline to 21.3%(87/409)at 6-month,and 22.7%(93/409)at 12-month.The awareness rate of nutrition knowledge of parents also fluctuated,from 5.6%(23/409)to 6.6%(27/409)and 5.4%(22/409).However,the difference in changes in nutrition knowledge between intervention and control groups was non-significant.The 6-month follow-up changes in children’s nutrition knowledge scores were negatively associated with changes in BMI in girls(β=−0.26,95%confidence interval[CI]:−0.38 to−0.14,P<0.001),while positively associated with changes in WHtR in boys(β=0.003,95%CI:−0.0002 to 0.005,P=0.035).The 12-month follow-up changes in children’s nutrition knowledge scores were positively associated with changes in children’s WHtR(β=0.003,95%CI:0.0004 to 0.01,P=0.018).Conclusions:The intervention strategies did not reduce the BMI and WHtR of children,and the nutrition knowledge of children and parents increased after the intervention in intervention group.Changes in nutrition knowledge of children and their parents are associated with changes in children’s BMI or WHtR.Interventions with a new focus on obesity are needed to help improve children’s nutritional status in poverty-stricken areas in Shaanxi Province of China.

文摘This study aims to investigate the mechanisms and health risks of fluoride enrichment in groundwater in the Loess Plateau,China.By taking Dali County,Shaanxi Province,China as an example,this study obtains the following results through field investigation and the analyses of water,soil,and crop samples.(1)The groundwater can be divided into two major types,namely the Quaternary pore-fissure water and Karst water.The Karst area and sandy area have high-quality groundwater and serve as the target areas for optional water supply.The groundwater in the study area is slightly alkaline and highly saline.Meanwhile,high-fluoride groundwater is mainly distributed in the loess and river alluvial plains in the depression area of the Guanzhong Basin and the discharge areas of the groundwater,with the highest fluoride concentration exceeding seven times the national standard.(2)Fluoride in groundwater mainly originates from a natural source and human activities.The natural source refers to the fluoride-bearing minerals in rocks and soil,and the fluoride from this source is mainly controlled by natural factors such as climate,geologic setting,pH,specific hydrochemical environment,ion exchange,and mineral saturation.Human activities in modern life can be further divided into industrial and agricultural sources primarily.(3)The health risks of fluoride contamination are very high in the Loess Plateau,especially for children compared to adults.Meanwhile,the risks of fluoride exposure through food intake are higher than those through drinking water intake.The authors suggest selecting target areas to improve water supply and ensure the safety of drinking water in the study area.Besides,it is necessary to plant crops with low fluoride content or cash crops and to conduct groundwater treatment to reduce the fluoride concentration in drinking water.These results will provide a theoretical basis for safe water supply in the faulted basin areas in the Loess Plateau.

文摘Studies on rocks and ores of Jianchaling ore deposit, southern Shaanxi, show that REE patterns in the ores clearly differ from that in ultrabasic and acidic rocks. The REE pattern in Ni ore is similar to that in Au ore and is characterized by typical enrichment in LREE and sharp negative Eu and Ce anomalies, indicating that Ni ore and Au ore were formed from the same hydrothermal solution. δ Eu and δ Ce variations reflect that Ni ore is formed at higher temperature and relative reduction environment, and Au ore at lower temperature and relative oxidation environment. The characteristics imply that the ore forming materials were derived from the ultrabasic rock and the hydrothermal solution is a post magmatic acidic solution.
