medium height mountain
Examples
- The improved nonlinear filtering mthod and its application in middle and high mountain areas
改进的非线性滤波方法在中高山地区的应用 - In middle and high mountain areas , the landform is complex , the flying altitude should be relatively high , and the intensity of magnetic anomalies detected by aeromagnetic survey is hence relatively weak
摘要中高山地区的地形复杂，飞行高度较高，航磁测量获得的磁异常强度相对弱小。 - Normally water resources is affected by human activities and climatic change , but it is affected mainly by climatic change in runoff forming regions located in the high and middle mountainous area in the northwestern china . river runoff in the hexi inland arid region all originates from the qilian mt . area and the change of mountainous runoff resulted from global weather warming up and will bring an important effect to the development of society and economy in the hexi region . so the response on mountainous runoff and its changing trends are analyzed on the basis of the measured data of precipitation , air temperature , and discharges observed from some weather and hydrologic stations in the studied area . the results show that seasonal variation of mountainous runoff in the hexi inland region is mainly affected by the river ' s geographical location and supply source , and the yearly change by precipitation and that in the west of the region by air temperature besides precipitation . there are some obviously regional differences in the influences of climatic change on surface runoff in the hexi inland arid region , that is , rivers runoff in the west of the hexi area have been increasing and rivers in the east part have been decreasing , and the rivers runoff in the central part presented slowly increase trend , such as the heihe river , but it is not quite obvious
一般情况下,水资源的变化主要受气候变化和人类活动的影响,但在位于我国西北内陆干旱地区的中高山地带,径流的形成主要受前者的影响.甘肃省的河西内陆干旱区是该省重要的工农业生产和经济开发区,这里各项社会和经济活动与出山径流的变化都有着十分密切的关系.因此,笔者根据有关水文气象台站的降水、气温和径流观测资料,分析了以黑河、昌马河、西营河等主要河流为代表的河西内陆区出山径流的变化特征与规律.结果表明,河西内陆区出山口径流的季节变化主要受地理位置和河流补给来源的影响,而年际变幅则受山区降水量年际变化及变幅的影响十分明显.目前,梨园河以西河流水量处于上升阶段,梨园河以东的河流则处于下降的阶段;以黑河干流莺落峡水文站年径流为代表的走廊中部地区的出山口径流正处于1990年开始的枯水段的上升段.但总体而言,河西内陆干旱区出山口径流的变化相对比较稳定.预计今后若干年内,河西内陆干旱区东段河流出山口径流的变化以偏枯为主,中段、西段河流出山口径流的变化以平水或平水偏丰为主 - The paper studies composition of grasshopper community in different habitats , found that differences in family , genus and species and analyzed the causes of those . the author analyzed the following aspects by spss software and the measure of euclidean distance : ( 1 ) analyzed the relationship between grasshopper species and geographical distribution and divided 9 forestry belt into 3 main habitat model : low mountain conifer and broadleaf integrated forestry belt ; low mountain chanbai conifer forestry belt and middle - high conifer - betula ermam / - tundra belt ; adopted sum of deviation of square to clustered ecological species groups , and thus divided 48 grasshopper species into 3 main category , 12 ecological species groups
在长白山地区蝗虫生态分布特点的研究中，主要应用spss软件包、采用euclideandistance测度法对以下两方面内容进行了分析： ( 1 )对长白山地区蝗虫地理分布关系进行了分析，将长白山9个林带划分为三大生境型：低山针阔叶混交林带、低山长白松林带和中高山针叶?岳桦?苔原复合体； ( 2 )利用离差平方和法对生态种组进行等级聚类，结合实地调查结果，将48种蝗虫划分为三大类12个生态种组。 - In order to utilize the magnetic anomaly information obtained by high - precision aeromagnetic survey more effectively , this paper , based on the reliable proof of the existence of weak magnetic anomalies in middle and high mountain areas and combined with characteristics of middle and high mountain areas , has advanced an improved nonlinear filtering method and described its effect in practical application
为了更有效地利用高精度航空磁法测量得到的磁异常信息，在充分论证中高山区弱磁异常存在的可靠性基础上，结合中高山地区特点，提出了改进的非线性滤波方法，并给出其实际应用效果。
