绿洲化是干旱区由于人与自然因素共同作用所导致的由荒漠向绿洲转变的过程。我国干旱区绿洲化面积从20世纪50年代后期的2.5万km2扩大到10.4万km2,绿洲化主要是改变了水循环,也就可以改善局部或更大范围的生态环境,提高生产力。可以说,绿洲化是一个将自然生态系统通过人类活动提升至人工生态系统的过程。但绿洲低水平、无序的开发也可以使绿洲稳定性下降和绿洲退化,在降低或丧失绿洲土地生产力的同时,还引发一
采用兰州大学半干旱气候和环境观测站(SACOL)2007年11月1日至2008年10月31日的APS-3321粒径谱仪的连续观测资料,对该地区大气颗粒物的浓度变化和粒径分布特征进行分析研究。结果表明,该地区颗粒物浓度年变化呈单峰值型,无论是数浓度还是质量浓度峰值均出现在12月,数浓度6月最低,质量浓度9月最低;和其他地区相比,无论数浓度还是质量浓度,均低于污染较严重的城市,但高于内陆清洁地区。数浓
The thermally and wind-driven ocean circulation is a complicated natural phenomenon in the atmospheric physics. Hence we need to reduce it using basic models and solve the models using approximate met

基于石油的荧光性,通过常规荧光光谱方法,对油包裹体的荧光光谱进行定量化描述,利用其主峰波长、最大荧光强度及红/绿商等属性参数,根据主峰波长与最大荧光强度、主峰波长与红/绿商的相关关系特征,可以便捷而有效地开展油气充注期次的判识.民丰洼陷沙三段岩性油气藏储层的15块流体包裹体样品检测结果表明,发黄色荧光的油包裹体荧光光谱结构和形态相似,其主峰波长一致;而发蓝白色荧光的油包裹体荧光光谱具有2种类型:一
