苍洱之滨玉菊飘香

滇西绵亘的群山是莲瓣兰的故乡,在苍洱之滨, 山水相依的云南大理,荡山洲兰园如期举办着一年一度的迎春兰花展览(每年1月1日-3月28日)。走进兰园,只觉满园春色,暗香沁人,绽放的花朵各显风姿。在满园的馨香中,一盆放花似菊的兰花引起了人们的关注。她就是经园主孙智勇精心栽培十余载的“玉菊”。     

兰花三剑客香飘四海

在云南省大理州剑川县县城里,有一个由中国兰花学会理事、中国兰花协会理事、云南省兰协副秘书长、剑川兰协法人代表陈述新创建的“云南兰花示范园”。走进客厅,墙上竖幅悬挂着由中国兰花协会副会长潘光华教授题写“剑湖菊、剑湖奇、剑阳蝶是兰花三剑客”     

纵向岭谷北部三江地貌演变的相似性——地貌参数统计关系证据及成办剖析

为了探讨滇西北纵向岭谷区北部并行而流的怒江、澜沧江和金沙江支流系统的演变特点及其相互关系,运用统计学方法分别对研究区上述3条河流的流域面积大于100km2的所有支流、一级支流和二级支流的有关地貌参数之间的相互关系进行了统计分析,拟合出了一系列相互关系式.结果表明,研究区上述3条河流的支流地貌体系具有非常高的相似性,对于一级支流的河道比降与流域面积来说尤其明显.相对来说,怒江和澜沧江的支流体系在河道长度与流域面积的统计关系上具有更多的共性,这尤其表现在总体支流以及一级支流当中;河道比降与流域面积的统计关系同样揭示了怒江和澜沧江具有更高的相似性,这尤其体现在总体支流关系中.造成上述相似性的原因在于,纵向岭谷区地质构造的相似性决定了地貌景观和物质条件的相似性,从而决定了支流体系演变的相似性.而怒江和澜沧江支流系统演变的高度相似性是由于它们同处于板块碰撞的前缘地带,都受到构造作用的极大控制;金沙江略为远离该前缘地带,构造的控制作用较弱,其支流的地貌演变相对自由.同时,气候相对干旱,导致沟谷中径流动力较弱,径流对地貌系统的改造能力相对有限,与怒江和澜沧江支流系统相比,除了明显的共性外还存在些许差别.     

Taxonomy, age and environment status of the Yuanmou hominoids

Fractal Characteristic of Soil in Typical Debris Flow.Triggering Region： A Case Study in Jiangjia Ravine of Dongchuan, Yunnan

The structural features of soil in debris flow-triggering region play an important role in the formation and evolution of debris flow. In this paper, a case study on the fractal of soil particle-size distribution （PSDFs） and pore-solid （PSFs） in Jiangjia Ravine was conducted. The results revealed that the soil in Jiangjia Ravine had significant fractal features and its PSDF and PSF had the same variation trend despite different type of soils in debris flow-triggering region： residual soil （RS） 〉 debris flow deposit （DFD）~clinosol （CL）, their fractal dimension of PSDFs are respectively between 2.62 and 2.96, 2.52 and 2.68, 2.37 and 2.52; and the fractal dimension of PSFs are respectively between 2. 75 and 2.95, 2. 57 and 2. 72, 2.59 and 2.64. The fractal dimension of soil reflected its complexity as a self-organizing system and was closely related to the evolution of soil in debris flow- triggering region.     

Effect of Land Use on Soil Properties in Debris Flow Bottomland： A Case Study at Xiaojiang Basin, Yunnan

In order to understand the effect of different land use on soil physics and nutrients properties of the debris flow bottomland, a case study at Daqing gully （in Xiaojiang Basin, Yunnan） was conducted in 2004. Soil samples were taken at depth of 0-10,10-20,20-40,40-60,60-80 cm under three land use patterns crop bottomland （CL）, forest bottomland （FL）, and barren bottomland（BL）. The results showed that the developing bottomland to CL promoted soil toaccumulate total phosphorus （TP） and available phosphorus （AP）, pH value transferred from neutral to alkalescency, and organic matter decreased significantly. Furthermore, the contents of total nitrogen （TN） and available nitrogen （AN） in CL were lower than that of FL and BL because the growth of crops consumed more nutrients in soil. The results also showed that the contents of TP, AP and available potassium （AK） in soil were positively correlated with soil particle.     

滇越铁路对近代云南社会和经济的影响

滇越铁路是云南历史上的第一条铁路.它的修建是十九世纪末、二十世纪初帝国主义侵略中国,在中国划分势力范围的结果.法帝国主义通过滇越铁路的修建,操纵它的管理权,大量推销他们的商品,获取廉价的农产品和矿产资源,严重影响着云南的经济和社会发展,给我国人民特别是云南人民带来了深重灾难.
