云南新平磨盘山自然保护区地貌特征分析

Analysis for Geomorphic Characteristics of Mopanshan Nature Reserve in Xinping of Yunnan

通过野外实地考察并参考有关文献,就云南磨盘山自然保护区的地貌进行研究,划分了保护区的基本地貌类型、分析了地貌特征及其生态环境效应。结果表明,磨盘山自然保护区的基本地貌类型为砂岩类侵蚀剥蚀中起伏中山、大起伏中山、大起伏亚高山,地貌成因类型有构造地貌、河流地貌、沟谷地貌、重力地貌、丹霞地貌;保护区整体地势中部高,向东北、西南两侧呈阶梯状下降,山体坡度大,河谷切割较深,相对高差大,区域地貌结构系大起伏中山、亚高山峡谷山原;受山脉走向影响,使河谷呈东南西北走向排列,气候、水文、土壤、植被等自然地理因素垂直分异明显。

The geomorphic characteristics of Mopanshan Nature Reserve in Xinping were studied to divide the basic geomorphologic types of the reserve and analyze the geomorphologic characteristics and ecological environmental effects based on field investigation and relevant literature. The results showed that the basic geomorphologic types of Mopanshan Nature Reserve were intermediate altitude mountain with intermediate undulating, intermediate altitude mountain with large undulating, and high altitude subalpine mountains with large undulating, and the geomorphic origins were tectonic landform, river landform, valley landform, gravity landform and Danxia landform. The overall topography of the reserve was high in the middle, with a step - like decline to the northeast and southwest. The slope of the mountain was large with deep valley and large relative height difference. Affected by the trend of mountains, the valleys were arranged in the direction of southeast and northwest, and the natural geographical factors such as climate, hydrology, soil and vegetation had obvious vertical differences.
