基于前人的研究成果,本文利用GIS软件对郑洛地区三个连续文化时期的史前聚落遗址的坡向、坡度分布情况进行了分析。研究结果表明,研究区中大部分聚落遗址分布在坡向朝南、坡度小于3°的地点,但是仍然有少部分遗址处于光照差、坡度较大的地点。 Based on the research results of predecessors, this paper analyzes the distribution of slope and gradient of prehistoric settlements in three consecutive cultural periods in Zhengluo area by GIS software. The results show that most of the settlements in the study area are located on the south facing slope with a slope of less than 3 °. However, a few of the sites are still in poor light and steep slopes.
