There are at least nine physiographic cycles in the middle reaches of the Yellow River during the Late Cenozoic Era. 在晚新生代黄河中游至少存在九个地文期旋回。
This paper analyzes of the influencing factors of residential district such as physiographic condition, traffic cost, social productivity and so on and evaluates the residential distribution in urban comprehensively using fuzzy synthetic evaluation method. 通过分析对居住区有影响的自然地理、交通费用、住房费用、地价的变动以及社会生产力等因素,用模糊合成的方法,对居住区在城市中所坐落的位置作出综合评价。
Under the same physiographic condition ( e.g., precipitation and topography), runoff varies with land uses in the following decreasing order of intensity: wasteland> cropland> fallow> grassland> woodland ( low cover)> shrub. 相同条件(降水,地形)下,不同土地利用类型产生径流的大小顺序依次为:荒地>农田>休耕地>草地>疏林地>灌木。

The two countries had much economical and cultural communication because of the influences of the physiographic condition, the development type ( cultivation or animal husbandry), the policies of the two sides etc., which developed the economy, culture and national reunification. 由于自然地理条件、经济发展类型(农耕、游牧)、双方政策等因素影响,宋夏在边境地区进行了大量的经济、文化等方面交流,促进了经济文化的发展与各民族间的融合。
During the investigation: physiographic, topographic contour and geological maps are studied in the office and used during the fieldwork. Slope angle in relation to lithology, dip and strike of rocks and fractures were measured, degree of weathering and bedding planes are determined. 在调查期间,分别在室内和室外对地形图和地质图进行分析,对斜坡的坡角、岩性、岩体的走向和倾角以及结构面进行了测量;确定了风化程度和层面。
Content: The spatial characteristic of the urban natural environment is the new direction of the modern physiographic research. 内容摘要:城市自然环境的空间特征是现代自然地理学研究的新方向。
