- The lower limit of the alpine zone varies in different mountain regions , according to the rainfall and other climatic and topographic factors , from 100 meters above sea level in parts of scotland to 3700 meters in the western himalayas
根据降水，气候和地形学上的因素，高山地区的最低限度在不同的山区是不同的，从苏格兰海平面上方100米到西喜马拉雅山的3700米。 - In this paper , based on land use maps of 1976 , 1988 , 2003 , which were interpreted from the landsat mss / tm / etm imageries , and the map of main road , with the buffer analysis tool in arcgis 8 , we studied the land use and land cover change on the two sides of the main roads in xishuangbanna , then we studied the impact of population density and the topographic factor on road effects . during the study both the comprehensive land use dynamic degree model and the land use degree comprehensive index model are taken into account , we put forward a compensatory model ? “ amendatory comprehensive land use dynamic degree model ”
由于人类活动干扰强度加大,公路效应深度不断扩展, 1976年为5km , 1988年为7km , 2003年达到11km ;受自然、社会条件的影响,不同路段的公路效应存在较大差异,甚至同一路段两侧效应也各不相同。 1976年至2003年,距公路不同距离范围内的人口密度都在增加,且距离公路越近,人口数量密度越大、增长越快,人口分布有向公路两侧聚集的趋势。选取人口密度为大、中、小三个样区分别分析公路效应的范围表明,人口密度 - Applying the basic theories of spatial data mining and geomorphology , taking the loess plateau of north shaanxi province , china as the research area , this dissertation explored the theories and systematic structures of geomorphologic data mining and acknowledge discovery from dems , ascertained the systematic structures of topographic factors and synthetic topographic acknowledge , as well as systemically summarized mining algorithms from dems . the author pa id more attention also to analyze the principle and algorithm of flow length , curvature , relief , the earth ' s surface incision and gully density . in this research , the elementary constitutes and mining algorithms of regional character acknowledge in the loess plateau were probed
本研究在广泛总结前人研究成果与研究经验的基础上，利用空间数据挖掘和地形地貌学的基本理论，以陕北黄土高原多地貌类型区为实验样区，以1 10000比例尺dem为样本数据，探讨了dem中地形地貌数据挖掘与知识发现的理论方法和体系结构；确定了宏观和微观地形因子、地形综合特征知识的体系结构；系统总结了dem基本地形因子的提取算法，并重点对坡长、曲率、地形的起伏度、切割深度和沟壑密度因子提取的原理与算法作了深入的分析；提出了黄土高原地区区域特征知识的基本构成及其系统完整、科学可行的挖掘提取算法；扩充了arcviewgis软件平台中dem空间分析的基本功能；实现了以delphi7 . 0为平台的地形信息辅助挖掘系统的设计与开发；完成了对黄土高原多地貌类型区(样区)地形信息空间分异特征的分析。 - In this dissertation three topographic factors were included , that is elevation , slope and aspect , among which the effect of slope was the strongest , elevation was the second and aspect was the last . besides topography , burn severity and anthropogenic disturbance were also important to the spatial pattern and the change of the forest landscape
论文所设计的地形因子? ?坡度、坡向和海拔，对景观格局的影响各有侧重，从其对各种不同景观斑块类型转化的影响来看，坡度的影响最强，其次是海拔，影响程度相对较小的是坡向。
