摘要

区域性是地理学的重要特点之一.本研究从区域差异性着手

应用对比方法

模拟研究了辽宁兴城和贵州威宁2个区域在铁路工程施工期工程措施所形成的各类人工地貌的侵蚀产沙、产流特征.结果表明

由于地表自然状况的南北区域差异

导致2个研究区在工程措施影响下的各类人为地貌的产沙产流具有明显的差异

具体表现为:北部研究区的产沙产流时间迟于南部;相同时间内累积产沙量、产流量则北部小于南部

表现出明显的地域差异性.

Abstract

Regionality is one of important characteristics of geography. The study

based on regional otherness

using contrastive method

simulated traits of soil erosion of all kinds of artificial physiognomy formed by engineer ing measures during construction period in both Liaoning Xingcheng city and Guizhou Weining county. The result showed

the regional otherness of upper natural environment both in south and north

resulted in obvious otherness of runoff and sediment yield of artificial physiognomy

which embodied that the time of runoff and sediment yield in north is late for that in south

but the quantity of runoff and sediment yield in north is less than that in south

which represented obviously regional otherness.
