Elevated CO_2 level in the atmosphere is expected to improve the tree growth rates and intrinsic water-use efficiency(i WUE).Although current results inferring from tree rings found the tree growth decline in water-limited area,it is still unclear whet

对中国沙尘暴源区之一的乌兰布和沙漠进行系统采样,分析不同土地覆被类型的地表沉积物粒度特征及其空间分异规律。结果表明:乌兰布和沙漠地表沉积物以中沙和细沙为主,平均粒径为2.84Φ。沙漠地表沉积物的粒度特征在不同土地覆被类型和不同空间存在明显的分异规律,表明该沙漠的地表沉积物粒度分布是由物源、地形和搬运营力共同作用的结果。乌兰布和沙漠内部最可能成为沙尘暴尘源的有沙漠中部的盐碱地、东北部的耕地和广泛存在
After the bursting of Huiten Nor in Hoh Xil Region in September, 2011, the topic on whether the water overflowed from the Salt Lake would enter into the Chumaer River and become the northernmost sourc
利用2006年6月至2012年12月的CALIPSO Level 2 VFM产品、5km分辨率的Aerosol Profile、Cloud Layer产品以及MISR反演的产品,揭示了东亚地区不同高度层上沙尘的时空分布特征,重点对比分析了东亚沙尘源区晴空和云上沙尘的垂直分布特征、消光系数和光学厚度。结果表明:塔克拉玛干沙漠和戈壁沙漠是东亚沙尘的主要源区,沙尘出现频率具有显著的季节差异,春季最多,夏
Land use/cover change is an important theme on the impacts of human activities on the earth systems and global environmental change. National land-use changes of China during 2010–2015 were acquired b
Urbanization significantly increases the risk of urban flooding. Therefore, quantitative study of urban rainfall-runoff processes can provide a scientific basis for urban planning and management. In t
Optimizing rural settlements is an important measure to cope with rural decline, and improve the quality of rural life and attractions. This study introduces the "life quality theory". Based on the me
对科尔沁沙地围封草地和放牧草地群落的种类组成、结构和多样性等特征进行比较研究。结果表明:(1)围封草地盖度、密度、地上生物量、高度均优于放牧草地(P<0.01)。与放牧相比,围封使植被盖度、密度、高度和地上生物量分别提高了237%、429%、77%和218%,植物群落结构得到明显改善。(2)与放牧草地相比,围封草地物种数增加了69%,多年生草本、灌木类种数和重要值均高于放牧草地。放牧草地的优势植物
利用2010年塔克拉玛干沙漠腹地塔克拉玛干沙漠大气环境观测试验站单波段(525nm)积分浊度计和PM10自动监测仪、能见度仪器观测资料,结合塔中地面气象观测资料,分析影响塔中气溶胶散射系数的各因子。结果表明:(1)散射系数和PM10质量浓度具有明显的正相关关系,相关程度秋季最大,达0.96;夏季次之,为0.94;冬季最小,为0.91。(2)质量散射系数3月最小,10月最大;四季中,春季最小,为0.
