"卡瓦格博"藏语意思是"河谷地带险峻雄伟的白雪山峰"。它是梅里雪山主峰,海拔6 740 m,藏区八大"神山"之首,处于世界闻名的"三江并流"地区,是云南第一高峰,也是全世界公认为最美丽的雪山,被誉为"雪山之神"。卡瓦格博峰如今仍是一座处女峰。卡瓦格博峰如此"高不可攀"的原因除了坡度陡和相对高差大等因素,还因为梅里雪山的冰川主要受印度洋气流影响,属于海洋性冰川,有运动变化快的特点。梅里雪山位于横断山

Recent developments of 30 m global land characterization datasets(e.g., land cover, vegetation continues field) represent the finest spatial resolution inputs for global scale studies. Here, we presen
The sensitivities of the initial value and the sampling information to the accuracy of a high accuracy surface modeling(HASM) are investigated and the implementations of this new modeling method are m
铁兰是一种不从土壤汲取养分的气生植物,在很多国家被用于空气污染的监测研究。虽然铁兰作为生物监测被广泛报道,但却很少有关于铁兰自身结构与其作为生物监测器间相关性的研究。由于它们从降水中吸收水分、养料以及大气污染物,因此,通过检测其组织中累积的重金属即可判断空气的主要污染源。为了进行环境监测,常需要依据土地使用类型、人类活动范围以及距离重金属源的距离进行分类采样,并且要区分农业、城镇、工业及交通区域,
