Spatiotemporal Change in Climate Variables and Resources of Wind, Solar Radiation and Precipitation in Qinghai Province from 1961 to 2021
Published 2024-12-01“…In order to evaluate the potential of wind, solar radiation and precipitation in guaranteeing the development of clean energy comprehensively, this study analyzed the temporal and spatial changes in climate variables and resources of wind speed, solar radiation and precipitation in Qinghai Province throughout the year and four seasons from 1961 to 2021 based on the observation data of daily 10-meter-height wind speed, sunshine duration and precipitation at 51 meteorological stations.The results are as follows: (1) The annual average wind speed, solar radiation and precipitation in Qinghai Province are 2.67 m·s-1, 6084.2 MJ·m-2, and 299.7 mm, respectively.Wind speed tends to be higher in the western regions and lower in the east, which exceeds 3 m/s and reaches the standard for wind energy resource development in western Qinghai.The annual solar radiation in the entire Province exceeds 5040 MJ·m-2, and reaches the "very rich" level according to China Solar energy GB Standards.The solar radiation of Qaidam Basin is at its highest abundance level, which is ideal for solar energy resource development.Precipitation generally decreases from southeast to northwest.The resources of wind, solar radiation, and precipitation in Qinghai Province exhibits seasonal complementarity, characterized by a pattern of “strong winds, good sunlight, and less water in spring, whereas weak winds, good sunlight, and abundant water in summer”.(2) Under climate change, the annual average wind speed and total solar radiation in Qinghai Province show a significant decrease at rates of 0.16 m·s-1·10a-1and 29.04 MJ·m-2·(10a)-1, respectively.The western and central parts of Haixi are most affected by these changes, but the wind speed and solar radiation still remain within the acceptable range for wind energy and photovoltaic resource development.Meanwhile, precipitation increases significantly at a rate of 8.85 mm·(10a)-1, with the largest increase observed in western Yushu, eastern Haixi and northern Guoluo.The most significant decrease in wind speed is observed in spring, while summer solar radiation decreases at the fastest rate but with a substantial increase in precipitation.The changes in solar radiation and precipitation could be ascribed to the increased cloud cover in this region.(3) The changes in the areas where wind speed and solar radiation meet suitable development standards in Qinghai Province are not significant with reduced variabilities, which could ensure the stable development of clean energy.Wind energy resources in western Qinghai (such as Tanggula Mountains), solar energy resources in the Qaidam Basin, and water energy resources in the three major river basins of the Yangtze River, Yellow River, and Lancang River have great potential for development.Overall, the results provide a theoretical foundation for the development of a balanced clean energy system encompassing wind, solar and hydropower.This contributes to achieving national "dual carbon" goals and enhancing the high-quality development of Qinghai Province.…”

Data-Driven-Based Attribution of Runoff Changes in Tuwei River Basin in the Northern Windy-Sandy Region of Shaanxi
Published 2022-01-01“…The key point in analyzing the attribution of runoff changes is whether the natural runoff process of the basin can be accurately simulated.However,the application accuracy of hydrological models in arid and semi-arid regions of the Loess Plateau is generally not high.Taking the Tuwei River basin in the northern windy-sandy region of Shaanxi in the middle reach of the Yellow River as an example,this paper proposed an improved natural runoff simulation method based on the data-driven approach,so as to quantitatively analyze the effects of climate changes and human activities on runoff changes in the Tuwei River basin.The results show that the annual runoff series in the basin decreased significantly from 1961 to 2015,and there were two abrupt changes in 1979 and 1996,respectively.The annual runoff of the two periods (1980—1996 and 1997—2015) is 25.8% and 47.1% lower than that of the natural period (1961—1979),respectively.The runoff simulation accuracy of the three data-driven methods after improvement rises significantly.Specifically,the improved method proposed by Zhao Wenlin has the highest accuracy,and the Nash-Sutcliffe efficiency coefficient of annual runoff simulation in the natural period is 0.77.Climate change is the main reason for the significant decrease in the runoff between 1980 and 1996 (with a contribution of up to 80.9%).However,from 1997 to 2015,the contribution of climate change and human activities to the decrease in the runoff changed,with the influence of human activities increasing to a proportion of 58.8%.…”

Study and Prediction of Land Use/Cover Change in Small and Medium-Sized River Basins in Typical Urbanization Areas
Published 2022-01-01“…In order to explore the spatio-temporal evolution pattern of land use in small and medium-sized river basins under the background of rapid urbanization,this paper studied the Baiyun Lake basin and analyzed the structure change in land use in the Baiyun Lake basin from 1980 to 2020 by using land use dynamic degree and land use intensity.In addition,the paper employed a standard deviation ellipse model to analyze the spatial pattern change in the basin,discussed the influence on the land use in the basin before and after the completion of Baiyun Lake,and utilized a CA-Markov model to simulate the land use in the basin in the 2030 and explore the pattern evolution trend of land use in the basin in the future.The results show that:① The land in the Baiyun Lake basin from 1980 to 2020 was mostly used for construction,with an average annual proportion of 51.77%,and in 2020,the proportion reached 70.13%.② In the past 40 years,the land use in the basin has changed from cultivated land,dry land,forest,and grassland to construction land.The land use intensity has continued to rise,and the land structure has gradually tended to be single.③ Baiyun Lake occupies part of the urban land,so the land use in the basin will focus on the adjustment of forest and construction land in 2030.The land use intensity will change slowly,and the urban construction space will be controlled to a certain extent.…”
