中文摘要	沙漠地区太阳能资源丰富且地表植被稀疏,非常适于太阳能资源开发。然而目前针对中国北方沙漠地区太阳能资源的评估仍然较少。本研究利用中国北方沙区(含沙漠、沙地、戈壁和盐碱地)46个太阳辐射站和189个常规气象站数据,基于极端梯度提升算法(xgboost)估算了太阳总辐射量,分析了总辐射量年、季和月的时空分布并进行太阳能资源评估。结果表明,中国北方沙区1990-2019年平均日照时数和太阳总辐射量为2927.90 h和5888.39 MJ·m~(-2),且以分别以22.48 h·(10a)~(-1)和8.66 MJ·m~(-2)·(10a)~(-1)的速率减少,但这种趋势并不显著(p>0.05)。日照时数和太阳总辐射量空间分布呈现出东西低中部高的特点,青海和甘肃河西的沙区总辐射量最高,在6300 MJ·m~(-2)以上,东北地区的沙地总辐射量最低,不足5300 MJ·m~(-2)。季节变化表现为夏季太阳总辐射量最大,春季次之,秋冬季最低。总体上看,青海和河西走廊西部沙区太阳能资源丰富,其他沙区较丰富,但就太阳能资源稳定度而言,仅青海、河西走廊南部沙区为较稳定,其他沙区为欠稳定或一般。因此,青海和甘肃河西沙区太阳能资源开发潜力最大,应加大对该区太阳能资源的开发投入,提高区域经济发展水平,改善沙区生态环境。
英文摘要	The solar radiation,as a kind of clean energy,is increasingly being developed in recent years under the background of energy crisis and global climate warming. An evaluation of the spatial patterns and storage of solar energy is of great importance for potential solar energy resources development. The deserts in northern China are characterized by abundant solar energy resources and sparse vegetation cover,which are very suitable for solar energy resources development. However,as the number of solar radiation observation stations in sandy regions of northern China is very limited,dedicated evaluation to solar energy resources in the sandy regions of northern China is still characterized by large uncertainties. In this study,data from 46 solar radiation stations and 189 common weather stations in the sandy regions(including deserts,sandy lands,Gobi,and salinity lands)of northern China were employed to estimate the global solar radiation based on a high-efficient machine learning model,i. e.,the xgboost algorithm. The solar resources were assessed by analyzing the spatiotemporal patterns of annual,seasonal,and monthly radiation. The results showed that the average sunshine duration and global solar radiation from 1990 to 2019 are 2927.90 h and 5888.39 MJ·m~(-2),respectively. The average decreasing rates of sunshine hours and solar radiation over the past thirty years were 22.48 h·(10a)~(-1) and 8.66 MJ·m~(-2),respectively, which were not significant at the 0.05 level. The spatial patterns of sunshine duration and total solar radiation were characterized by higher values occurring in the middle parts while lower values in the east and west parts of northern China. The radiation was maximal in the deserts of Qinghai and Hexi Corridor with values higher than 6300 MJ·m~(-2),while minimum in the sandy lands of Northeast China with values less than 5300 MJ·m~(-2). The solar radiation was maximal in summer,followed by spring,and the lowest in autumn and winter. Generally, solar energy in deserts of the Qinghai and west Hexi Corridor were ranked as the most abundant level,while other sandy regions were very abundant level. However,in terms of the stability of solar energy,only deserts in the Qinghai and the southern Hexi Corridor were ranked as a relatively stable level,and other sandy regions are fewer stable levels. Therefore,the potential of solar energy resources in the sandy regions of Qinghai and Hexi Corridor was maximal,and should be given priority in terms of solar resources development,to promote the regional economic development and further improve the ecological environment of sandy regions.
