选择我国西北地区水土流失较为严重、具有典型风蚀、水蚀交互侵蚀特点的内蒙古乌兰察布荒漠草原作为研究区域,采用实地调查、遥感解译和野外动态观测相结合的方法,对荒漠草原风水交互侵蚀特征进行初步的分析研究。研究结果表明:气象因子是影响风水两相侵蚀的主要因子之一,其中风速和降雨量的影响较为明显。人为因子也是区域风水交互侵蚀的重要驱动因素之一,主要包括人口增长压力、滥垦滥牧及旅游践踏等因子,对区域风水交互侵蚀的发展具有直接的诱导和加剧作用。因此,减少人为因素的干扰是使草原可持续发展的重要途径。
The Wulanchabu desert steppe in Inner Mongolia, which is characterized by severe erosion and water erosion, is selected as the study area in northwestern China. Based on the combination of field survey, remote sensing interpretation and field observation, Erosion characteristics of the preliminary analysis. The results show that the meteorological factors are one of the main factors that affect the erosion of two phases in Feng Shui, of which wind speed and rainfall are more obvious. Human factors are also one of the important driving factors for the regional erosion and feng shui interaction. These factors include the pressure of population growth, over-priming and over-riding and tourism trampling, which directly induce and exacerbate the development of regional erosion and feng shui. Therefore, to reduce the interference of human factors is an important way to make grassland sustainable development.
