以地貌、土壤、坡向、坡度、高程5个指标构建郑洛地区史前聚落遗址人居环境指数模糊综合评价体系,使用基于地理探测器的因子探测法确定各单因素权重,根据环境驱动因子分级标准及等级值,采用梯形和三角形隶属函数计算单因素评价值,再使用加权平均的综合评价类型和等距法,得到了郑洛地区史前聚落遗址人居环境指数综合等级,运用SPSS数据探索功能,分析宜居度最高地区的具体环境特征,并分别以仰韶后期和龙山时期的实际遗址分布数据对该等级评价系统的准确性进行验证。研究结果表明,该模型评价结果较为准确可靠。
The fuzzy comprehensive evaluation system of Habitat Environment Index of prehistoric settlements ruins in Zhengluo area was constructed based on five aspects of landform, soil, aspect, slope and elevation. The weight of each single factor was determined by factor exploration method based on geography detector. According to environmental drivers, Standard and grade value, using the trapezoidal and triangular membership function to calculate the single factor evaluation value, and then using the weighted average of the comprehensive evaluation type and the equidistant method, we get the comprehensive hierarchy of the Habitat Environmental Index of prehistoric settlements in Zhengluo area, and use the SPSS data exploration function , Analyzes the specific environmental characteristics of the area with the highest degree of livability, and verifies the accuracy of the rating system with the actual site distribution data in the late Yangshao period and Longshan period respectively. The results show that the model evaluation results are more accurate and reliable.
