摘要
尝试利用GIS技术模型化、定量化研究历史地理问题,旨在为各种农作物传播路径研究和物质、文化扩散等历史地理课题研究提供一条新的研究思路和技术路线。为探究玉米进入中国后的传播路径和扩散过程,以中国各地最早有玉米记录的文献及记录时间为基础数据,建立玉米在中国传播的数字地面模型,利用定量和模型分析的方法研究玉米在中国的传播起点、方向、主线与扩展速度,探究其扩散区域面积与明末以来人口增长的关系。结果表明,玉米在明嘉靖年间传入中国,在甘肃西部(1522年)、云南东南部(1563年)、广西东南部(1564年)、福建东部(1545年)形成4处独立的传播源,沿8条线路传向全国。玉米的传播主要是沿陆路交通线传播,清代官路与大路对玉米的传播促进作用明显;但在我国西南地区,由于地形复杂、陆路交通不便,玉米的传播主要沿河谷方向拓展。清代以来玉米在中国快速扩散种植,中国人口快速增长,二者表现为明显正相关关系,玉米的广泛引种是清初到1950年中国人口能够快速增长的原因之一。
In this study,GIS technology was used for modelization and quantification research on historical geographic issues to provide a new research approach and technical route for the study on various crop transmission pathways and historical geographic issues such as material and cultural diffusion.In order to explore the transmission path and diffusion process of corn after its entry into China,a digital ground model of corn transmission in China was established based on the earliest recorded literature and time in various parts of China.Quantitative and model analysis methods were used to study the starting point,direction,main line,and expansion speed of corn transmission in China,and explore the relationship between its diffusion area and population growth since the late Ming Dynasty.The results showed that during the Jiajing period of the Ming Dynasty,corn was introduced to China and formed four independent sources of transmission in western Gansu(1522),southeastern Yunnan(1563),southeastern Guangxi(1564),and eastern Fujian(1545),spreading along eight routes to the whole country.The spread of corn in China was mainly along land transportation routes,and the promotion of corn dissemination by official roads and highways in the Qing Dynasty was significant.However,in the southwestern region of China,due to complex terrain and inconvenient land transportation,the spread of corn mainly extended along river valleys.Since the Qing Dynasty,corn had been rapidly spread and cultivated in China,and the population in China had grown rapidly.The two had shown a significant positive correlation.The widespread introduction of corn was one of the reasons for the rapid population growth in China from the early Qing Dynasty to 1950.
