本文研究区域介于吕梁山分水岭至黄河中游峡谷之间,大部分属于黄土高原,习惯上称为晋西和晋西北地区。这里,生态环境多样,人类活动频繁,土地演替方向不同,速度不一,亟待进行土地动态研究。为此,本文从土地演替影响因素分析入手,通过对土地演替模式,方向和速度的讨论,提出对土地演替的控制思想和土地调控措施,目的为合理开发利用黄土高原土地资源提供依据。
The research area in this paper lies between the Luliangshan watershed and the canyon in the middle reaches of the Yellow River, and most of them belong to the Loess Plateau, which is customarily called Jinxi and Northwest Shanxi. Here, diverse ecological environment, frequent human activities, different direction of land succession, different speeds, the urgent need for land dynamics research. Therefore, this paper starts with the analysis of the influential factors of land succession, and puts forward the thought of controlling land succession and land regulation and control by discussing the land succession pattern, direction and speed. The purpose is to provide the basis for rational exploitation and utilization of land resources of the Loess Plateau .
