【摘要】：基于孢粉、炭屑顯微結(jié)構(gòu)、古土壤遙感資料 ,并結(jié)合西遼河流域文化景觀的時(shí)空格局 ,探討了人地關(guān)系相互作用機(jī)制。歷史時(shí)期西遼河流域的環(huán)境變化有兩個(gè)適宜期和兩個(gè)欠適宜期 ,與此相適應(yīng) ,文化景觀則表現(xiàn)為農(nóng)業(yè)文化的 3次興盛 :上古農(nóng)業(yè)文化興盛期 ;中古農(nóng)業(yè)文化興盛期 ;近代農(nóng)業(yè)文化興盛期。在這 3個(gè)農(nóng)業(yè)興盛期中 ,人類生態(tài)足跡逐漸擴(kuò)大 ,對(duì)資源的利用程度逐漸加強(qiáng) ,對(duì)該區(qū)域的景觀面貌的影響逐漸增大。西遼河流域景觀演變不表現(xiàn)為簡(jiǎn)單的南北擺動(dòng) ,而是表現(xiàn)為區(qū)域尺度上景觀的“彈性變化”。
[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.
