依据哈巴雪山自然保护区及附近气候观测资料,应用气候学方法和原理,综合分析该自然保护区垂直气候要素,分析中发现,光照、气温、降水等气候要素,随海拔升高,垂直分异明显。依据气候特征的垂直变化,结合植被及土壤的分布,参照划分垂直气候带的标准,将保护区划分为7种气候带:河谷中亚热带、河谷北亚热带、山地暖温带、山地中温带、山地寒温带、高山寒带、高山永久冰雪带。分析结果表明:保护区垂直气候带特征分异明显,气候类型丰富多样;山地寒温带、高山寒带等地区,生态高度敏感脆弱。  相似文献

南迦巴瓦峰地区垂直气候带及气候类型   总被引:1,自引:1,他引:0  
南峰地区岭谷高差悬殊(达5000—7000米),这就破坏了当地的纬向气候带。与其他山区一样,南峰地区随海拔高度的不同,热量条件和水分状况差异明显,形成不同的垂直气候带。总的来说,这里属于藏东南亚热带山地湿润气候区,但由于地势起伏变化很大,一地并存各种气候带,独成一特殊的气候生态区域。  相似文献

以位于纵向岭谷区核心区域的云龙天池自然保护区为研究对象,通过分析保护区气温及降水两大要素的垂直变化,依据气候要素变化特征,结合云南省热量资源区划指标系统及山地热量带划分原则,将保护区划分为6个垂直气候带:澜沧江河谷南亚热带半湿润气候带、澜沧江河谷中亚热带湿润气候带、低中山山麓北亚热带湿润气候带、中山南温带湿润气候带、高中山中温带湿润气候带、高山寒温带潮湿气候带。对各垂直气候带内气候、生物特征进行分析,结果表明:各气候带界限明确,发育符合本气候带热量水分条件的植被及土壤;山麓底部发育有符合水平地带性规律的基带,基带垂直向下的河谷地带发育负向气候带;保护区南温带及以上的气候带,气温偏低,生态系统脆弱。  相似文献

从赤道到两极,有规律地排列组合的气候地带的总体叫做水平气候带谱。水平气候带谱分为西岸型、内陆型和东岸型三种,这是纬度地带性规律的反映。非纬度地带性因素对水平气候带谱的影响表现在气候地带的长度和宽度发生了变化。各大洲气候他带分布格局是三种气候带谱的组合。  相似文献

横断山区气候区划   总被引:2,自引:1,他引:1  
本文在研究横断山区气候区划时发现,以往采用的划分区内气候带指标不连续,带谱不衔接.经采用统一的划分指标后,在横断山区内部划分出了一个山地暖温带。该带带域虽较窄,但填平了一条“鸿沟”,使青藏高寒和东部季风两个气候大区得以自然衔接。  相似文献

在总结前人确定山地冰川物质平衡线高度的各种方法基础上,对利用山地冰川物质平衡线进行古气候恢复的方法进行探讨。以我国乌鲁木齐河流域一号冰川为例,运用侧碛垄最大高度法确定了小冰期第二次冰进时冰川的平衡线高度,依靠1960年代以来该冰川所积累的大量观测资料,建立和完善现代冰川平衡线高度与气候统计关系公式,并通过变化应用到该冰川小冰期第二次冰进。给出了该次冰进时气候的半定量推算结果。  相似文献

一、确定气候带:根据试题所给气温资料,对照各气候带中的气温指标,确定该地属于何种气候带。 二、如果是属于热带型的气候类型: 1、首先考虑是否属于热带沙漠气候和热带雨林气候。如果是热带沙漠气候,必须符合终年高温雨水极少的气候特点;如果是热带雨林气候,必须符合多雨,各月气温和降水数值变化不大的条件。 2、如果试题所给条件不符合上述两种气候类型,就需要考虑是属于热带季风气候,还是属于热带草原气候。区别这两种气候类型比较困难,方法有:  相似文献

"泥炭气候成因说"的探讨   总被引:4,自引:2,他引:2  
殷书柏  吕宪国 《地理科学》2006,26(3):321-327
文章从沼泽有机质积累的本质和泥炭的定义出发,通过对地带性气侯与沼泽小气候、泥炭的现状分布与自然分布、“没有泥炭分布”地区与“不能形成泥炭”地区、地区差异与地带性分异规律等几对矛盾在泥炭形成与分布中的作用和地位的详细剖析,认为:各种地带性气候条件下都能因为地表积水而形成湿地小气候,不同地带内湿地小气候都具有湿润的特征;泥炭沼泽的形成与分布主要是与湿地小气候及积水厌氧环境有关,用与泥炭形成没有直接联系的地带性气候指标来研究泥炭形成与分布的规律性是不合逻辑的;地带性的水热条件主要对泥炭在不同地带的分布面积起到一定的控制作用;泥炭现状分布因为人类活动的影响已不是自然规律的表现,从不能反映泥炭形成与分布自然状况的泥炭现状分布来分析泥炭形成与分布的自然规律,显然也不能得出正确的结论;“没有泥炭分布”的地区并不是因为这里的水热条件组合不能形成泥炭,各自然地带内都可形成泥炭且所有地带内的泥炭特征都是相似的,没有必要将它们区别对待,这些事实说明“泥炭气候成因说”对泥炭形成与分布的规律性的解释是不合逻辑的,泥炭的分布不具有地带性的规律。  相似文献

Based on the citrus temperature, precipitation, sunlight and climate risk degree, the article divides subtropics of China into three types: the low risk region, the moderate risk region and the high risk region. The citrus temperature risk increases with increasing latitude (except for the western mountainous area of subtropics of China). The citrus precipitation risk in the central part of subtropics of China is higher than that in the northern and western parts. The distributions of citrus sunlight risk are not consistent to those of the citrus precipitation risk. The citrus climate risk is mainly influenced by temperature. There is latitudinal zonal law for the distribution of the climate risk, that is, the climate risk increases with increasing latitude. At the same time the climate risk in mountainous area is high and that in eastern plain area is low. There are differences in the temporal and spatial changes of the citrus climate. In recent 46 years, the citrus climate risk presents a gradual increasing trend in subtropics of China, especially it has been increasing fast since the 1980s. Because of the global warming, the low risk region in the eastern and southern parts has a gradual decreasing trend, however, the high risk region in the northern and western parts has an increasing trend and the high risk region has been extending eastward and southward. The article analyses the distribution of the citrus climate risk degree of reduction rates of >10%, >20% and >30% in subtropics of China, and studies their changes in different time periods. Results show that the risk is increasing from southeast to northwest.  相似文献

The influence of monsoon climatic characteristics makes the tropics of China different from those of other parts of the world. Therefore, the location of the northern boundary of China's tropical zone has been one of the most controversial issues in the study of comprehensive physical regionalisation in China. This paper introduces developments in the study of the northern boundary of China's tropical zone, in which different scholars delimit the boundary with great differences based on different regionalisation objectives, indexes, and methods. The main divergence of opinion is found in different understandings of zonal vegetation, agricultural vegetation type, cropping systems, tropical soil type and tropical characteristics. In this study, we applied the Geo Detector model, which measures the spatial stratified heterogeneity, to validate the northern boundaries of the tropical zone delimited by six principal scholars. The results show that the mean q-statistic value of the higher latitude boundary delimited by Ren Mei'e is the largest(q=0.37), suggesting that, of the rival views, it best reflects the regional differences between China's tropical and subtropical zones, but it is not necessarily suitable for guiding the development of tropical agriculture. The mean values of the q-statistics of Zheng Du's line and Yu Xianfang's line around the Leizhou Peninsula at a lower latitude were smaller, at 0.10 and 0.08 respectively, indicating that the regional differences were smaller than those of Ren Mei'e's boundary. Against the background of global climate change, the climate itself is changing in fluctuation. It is, thus, worth our further research whether the northern boundary of the tropical zone should not be a fixed line but rather should fluctuate within a certain scope to reflect these changes.  相似文献

The Qinling-Daba Mountains are the main body of China's North-South Transitional Zone.Analysis of the north-south gradual variation of vegetation components is significant for understanding the structural diversity and complexity of this transitional zone.In this study,based on survey data of plant communities,the eastern Qinling-Daba Mountains is divided into four geographic units:the north flank of eastern Qinling Mts.,south flank of eastern Qinling Mts.,north flank of eastern Daba Mts.and south flank of eastern Daba Mts.We also explore division of regional climate according to areal differentiation of plant-species,com-munity structure and species-richness,respectively.The results show that,(1)at plant-species level,there are mainly northern plants in north flank of eastern Qinling Mts.with evergreen species and fewer northern plants in south flank of eastern Qinling Mts.;there are mainly southern plants in eastern Daba Mts.(2)At community structure level,there are 4 formations(3 northern formations and 1 widespread formation)in north flank of eastern Qinling,6 formations(3 northern formations,1 southern formation,and 2 widespread forma-tions)in south flank of eastern Qinling,4 formations(2 southern formations and 2 widespread formations)in north flank of eastern Daba Mts.,and 3 formations(3 southern formations)in south flank of eastern Daba Mts.In terms of the numbers and properties of formations,there is a mixture of northern and southern formations only in the south flank of eastern Qinling Mts.(3)At species-richness level,the diversity of families,genera and species decreased with increasing latitude,but the mixing of northern plants and the southern plants began to occur in south flank of eastern Qinling Mts.This means that the south flank of the eastern Qinling Mts.serves more suitably as the dividing line between China's warm temperate and sub-tropical zones.  相似文献
