摘要
通过对陕北唐代以来聚落型遗址的数量、分布等信息的提取,结合历史时期气候冷暖波动情况,对近1300年来的聚落遗址数量和空间发生变化的控制因素进行了探讨。近1300年来研究区域内聚落遗址数量在不断减少,分布范围在空间上呈现出向毛乌素沙地东南缘靠近的趋势。通过重建大批古聚落遗址在时间和空间上的分布变化情况,我们可以发现其控制性因素可能并非为沙漠化或气候变化,统治者所采取的相关政策可能更为重要。在研究时段内,唐朝对生存于该区域的党项族采取羁縻府州制度进行管理,宋夏对峙时期党项族重视发展农业,宋政府也注意在当地的农业开拓;元明清时期为聚落址减少时期,统治者对研究区多采取封禁管理。管理政策更多成为近1300多年来聚落遗址数量变化的控制因素。
By extracting the data of the number and spatial distribution of settlement sites in northern Shaanxi since Tang Dynasty, and combining the climate fluctuation in historic periods, we studied the controlling factors that affected the changes of the number and space of settlement sites in study area in last 1500 years. The number of settlement sites decreased temporally and decreased spatially from northwest to southeast gradually. By reconstructing the temporal - spatial distribution of settlement sites, we found that its controlling factors were dosely related to the policies instead of desertification and climate change. Within the study period, the government implemented Jimufuzhou system to Dangxiang Nationality in Tang Dynasty. During the confrontation of Song and Xixia Dynasties, the Dangxiang people attached importance to develop agriculture, so did Song Dynasty. In Yuan, Ming and Qing dynasties, the number of settlement sites decreased, the government adopted the prohibi- tion policy in the study area. The national policy was the main controlling factor for the change of settlement sites in study area.
