全球变暖增加了当地大气对水分的需求,导致许多地区降水减少,两者都会导致干旱。水汽可以在辐射冷却到露点温度以下的表面凝结成露水。露水因其对地表水平衡的重要贡献而被认为是一个重要水源,尤其是在半干旱和干旱地区。干旱地区,年露水量占降雨量的9%-23%。在热带岛屿旱季,露水可以作为一种替代水源。露水对干旱地区或干旱期植物的生存、生长和发育十分重要,例如带来夜间水分以及通过植物气孔或特殊的物理特征(如气生植物)直接被叶片吸收利用。因此,露水可以增加叶片的净光合产物积累,提高植物水分利用效率。露水还参与了大气中的化学过程,例如亚硝酸盐氧化物的昼夜(和夜间)循环。从1961-2010,中国露水频率降低了5.2天/10年,这主要是因为近地表增温和相对湿度(RH)下降。此外,中国干旱区露水频率下降率(50%)高于半湿润和湿润地区(40%和28%)。因此,随着全球气候变化,不同地区露水具有不同的趋势,需了解...

随着人类社会工农业现代化、城市化的发展,人为因素造成土壤重金属污染是当今世界越来越不容忽视的环境问题。尽管煤矿资源的开发对社会经济至关重要,但其对自然环境产生的不利影响也是不可避免的。因此,我们有必要调查露天煤矿的土壤重金属分布,以发现受污染的农田,提供和制定土地复垦策略以及进一步的公共健康策略。原位土壤采样与实验室化学分析方法(利用高精度的原子吸收光谱法(AAS)和电感耦合等离子体质谱法(ICP-MS))相结合,已广泛应用于土壤重金属浓度的调查和制图。然而,该方法难以获得连续的土壤重金属浓度制图、耗时费力、成本高、效率低,适用范围小,且可能会再次对环境产生不利影响。遥感技术的发展为快速、高效、大尺度监测重金属含量提供了新的视角。而部分所使用的高光谱传感器存在数据质量差、图像连续性受限、光谱范围窄、空间分辨率低、需要辅助环境变量、易受大气干扰等问题。与现有高光谱卫星传感器相比,GF-5 A...

【温室气体】人类活动造成温室气体排放急剧增加,全球地表温度持续上升,显著改变了自然生态系统碳水循环格局。极端气候事件,尤其是极端干旱事件发生的频率和强度不断升高,对土壤含水量、土壤微生物群落结构和功能、土壤异养呼吸(Rh)以及土壤甲烷(CH4)通量具有重要影响。高寒泥炭地拥有巨大的碳储量,对气候变化高度敏感。虽然目前围绕高寒泥炭地碳排放开展了一些研究,但对高寒泥炭地生态系统碳排放对极端干旱响应的微生物机制仍不清楚。基于此,中国林业科学研究院湿地研究所的研究团队以青藏高原东部若尔盖国家级自然保护区高寒泥炭地(33°47′56.62′′ N,102°57′28.44′′ E,3430 m.a.s.l.)为研究对象,依托模拟极端干旱的野外控制实验平台,通过原位观测和室内试验相结合,旨在解决以下问题:(1)不同植物生长期,极端干旱如何影响Rh和CH4通量?(2)极端干旱如何影响...

CO2和CH4排放增加是全球变暖的主要原因(IPCC,2013),人类活动导致大约44%和60%的CO2和CH4排放到大气中。人类活动如拦河筑坝干扰湿地的结构和功能,引发大量土壤CO2和CH4排放。然而,目前对湿地水库CO2和CH4排放及其碳同位素特征的影响机制知之甚少。基于此,为了填补研究空白,在本研究中,来自云南大学和中科院武汉植物园的研究团队在三峡消落区原位条件下调查了4个海拔梯度(即不同淹水状态)(175 m,160–175 m,145–160 m和<147 m)饱和和排干状态下CO2和CH4排放模式及其碳同位素特征,以及相关的控制因子。他们作出了如下假设:1)由于淹水下优势植物种的转变,土壤条件(例如土壤基质质量,土壤水分和温度)的变化将会改变CO2排放以及CO2的δ13C值;2)CH4排放模式及其同位素特征对淹水更敏感,反映了土壤厌氧环境的增加;3)不同淹水状态下(例如饱和和排...
