【摘要】：基于孢粉、炭屑显微结构、古土壤遥感资料 ,并结合西辽河流域文化景观的时空格局 ,探讨了人地关系相互作用机制。历史时期西辽河流域的环境变化有两个适宜期和两个欠适宜期 ,与此相适应 ,文化景观则表现为农业文化的 3次兴盛 :上古农业文化兴盛期 ;中古农业文化兴盛期 ;近代农业文化兴盛期。在这 3个农业兴盛期中 ,人类生态足迹逐渐扩大 ,对资源的利用程度逐渐加强 ,对该区域的景观面貌的影响逐渐增大。西辽河流域景观演变不表现为简单的南北摆动 ,而是表现为区域尺度上景观的“弹性变化”。
[Abstract]:Based on the microstructures of sporopollen, carbon debris and remote sensing data of paleosol, and combined with the spatial and temporal pattern of cultural landscape in the West Liaohe River Basin, the interaction mechanism between man and land was discussed. In the historical period, there are two suitable periods and two less suitable periods for the environmental change in the West Liaohe River Basin, and the cultural landscape is manifested as three prosperous periods of agricultural culture: the flourishing period of ancient agricultural culture; The middle ancient agricultural culture flourished; the modern agricultural culture flourished. During the three periods of agricultural prosperity, the ecological footprint of human beings was gradually expanded, the utilization of resources was gradually strengthened, and the influence on the landscape appearance of the region was gradually increased. The landscape evolution of the West Liaohe River Basin is not a simple north-south swing, but a "elastic change" of the landscape on a regional scale.
