Geodynamic mechanism responsible for the generation of Silurian granitoids and the tectonic evolution of the Qilian orogenic belt remains controversial. In this study, we report the results of zircon U–Pb age, and systematic whole-rock geochemical data for the Haoquangou and Liujiaxia granitoids within the North Qilian orogenic belt and the Qilian Block, respectively, to constrain their petrogenesis, and the Silurian tectonic evolution of the Qilian orogenic belt. Zircon U–Pb ages indicate that the Haoquangou and Liujiaxia intrusions were emplaced at423 ± 3 Ma and 432 ± 4 Ma, respectively. The Haoquangou granodiorites are calc-alkaline, while the Liujiaxia granites belong to the high-K calc-alkaline *** are peraluminous in composition and have relatively depleted Nd isotopic [ε_(Nd)(t) =(-3.9 – + 0.6)] characteristics compared with regional basement rocks, implying their derivation from a juvenile lower crust. They show adakitic geochemical characteristics and were generated by partial melting of thickened lower continental crust. Postcollisional extensional regime related to lithospheric delamination was the most likely geodynamic mechanism for the generation of the Haoquangou granodiorite, while the Liujiaxia granites were generated in a compressive setting during continental collision between the Qaidam and Qilian blocks.

作者： Haiyan Wang Liangcai Guo jiuquan meteorological bureau in gansu province

[ Objective] The research aimed to study climatic change in Qinghai -Tibet Plateau and the surrounding areas from 1880 to 2011. [ Method] Based on GISS temperature grid data, by using change rules of the annual and monthly anomaly temperatures, sliding t-test and wavelet analysis, periodicity and tendency of the atmospheric temperature change in Qinghai -Tibet Plateau and the surrounding areas were analyzed. [ Re- sult] Both annual and monthly anomaly temperatures in Qinghai -Tibet Plateau in recent 130 years presented rise tendency. Since the 1990s, tem- perature rose evidently, and it presented temperature-rise tendency of winter 〉 autumn 〉 spring 〉 summer. Rise velocity of the temperature had spatial difference. Rise velocity of the temperature in west Inner Mongolia was the highest, followed by west Sichuan and east Tibet. Rise velocity of the temperature in some areas of Xinjiang was the slowest. Abrupt change of the temperature happened in the 1930s, and main period of the wavelet analysis was 10 years. [ Conclusion] The research could lay foundation for discussinq Qlobal climate change.

作者： Cao Hua Yin Lixia Yang Lili Chen Qingshan Wang Yuhong jiuquan meteorological bureau Jiuquan 735000 China gansu meteorological bureau Lanzhou 730020 China

Based on the observation data of PM 10 mass concentration, ground meteorological elements and solar radiation in Dunhuang and jiuquan , the changing trends of PM 10 mass concentration and solar total radiation in the west of the Hexi Corridor in the spring of 2014 (from March to May) were studied, and the relationship between solar total radiation and net radiation in different pollution situations was analyzed. Moreover, the changes of solar radiation and PM 10 mass concentration in a typical dust process in April 2014, as well as the responses of ground meteorological elements were also analyzed. The results showed that in the west of the Hexi Corridor, solar total radiation and PM 10 mass concentration showed an increasing trend with fluctuation, and there was inverse correlation between them. The correlation was particularly obvious in dust days. The dust weather led to the increase of PM 10 mass concentration, so that the total radiation decreased. The net radiation declined in the daytime and rose at night. Dust weather is a major factor affecting air quality and total radiation.

Influence factors and variation characteristics of water vapor absorption by soil in semi-arid region

作者： ZHANG Qiang WANG Sheng WANG ShanShan ZHAO YingDong WEN XiaoMei Key Laboratory of Arid Climatic Change and Reducing Disaster of gansu province Key Open Laboratory of Arid Climate Change and Disaster Reduction of CMA Institute of Arid Meteorology Lanzhou 730020 China gansu meteorological bureau Lanzhou 730020 China Key Laboratory for Semi-Arid Climate Change of the Ministry of Education College of Atmospheric Sciences Lanzhou University Lanzhou 730000 China Hydrology and Water Resources bureau of gansu province Lanzhou 730000 China Shanghai meteorological Service Shanghai 201901 China

The adsorption of water vapor by soil is one of the crucial contributors to non-rainfall water on land surface, particularly over semi-arid regions where its contribution can be equivalent to precipitation and can have a major impact on dry agriculture and the ecological environment in these regions. However, due to difficulties in the observation of the adsorption of water vapor,research in this area is limited. This study focused on establishing a method for estimating the quantitative observation of soil water vapor adsorption(WVA), and exploring the effects of meteorological elements(e.g., wind, temperature, and humidity) and soil environmental elements(e.g., soil temperature, soil moisture, and the available energy of soil) on WVA by soil over the semi-arid region, Dingxi, by combining use of the L-G large-scale weighing lysimeter and meteorological observation. In addition, this study also analyzed the diurnal and annual variations of WVA amount, frequency, and intensity by soil, how they changed with weather conditions, and the contribution of WVA by soil to the land surface water budget. Results showed that WVA by soil was co-affected by various meteorological and soil environmental elements, which were more likely to occur under conditions of relative humidity of 6.50% and the diurnal variation of relative humidity was large, inversion humidity, wind velocity of 3.4 m/s,lower soil water content, low surface temperature and slightly unstable atmospheric conditions. There was a negative feedback loop between soil moisture and the adsorption of water vapor, and, moreover, the diurnal and annual variations of WVA amount and frequency were evident—WVA by soil mainly occurred in the afternoon, and the annual peak appeared in December and the valley in June, with obvious regional characteristics. Furthermore, the contribution of WVA by soil to the land surface water budget obviously exceeded that of precipitation in the dry season.
