摘要
以渤海全境内遗址为研究对象,利用GIS空间分析技术,分析了渤海国遗址空间分布与环境之间的关系。结果表明：渤海国遗址数量中国最多,其次为俄罗斯和朝鲜,各类遗址中聚落址和平原城最多,其他遗址相对较少;71.5%的渤海国遗址分布在低洼平原和河谷平原较多的100~400 m高程内,随着海拔的增高,遗址数量逐渐减少;各类遗址中坡度较缓的有平原城、聚落址、建筑址、寺庙址等,其他遗址坡度较大,特别是山城址坡度最大;73.0%的渤海国遗址坡向为日照条件较好的南、西南、东南、东向、坪地,而其他坡向的遗址较少;65.9%的遗址分布在600m以内河流缓冲区内,此范围以外,随着距离的增加遗址数也逐渐减少,显示出明显的距离衰减规律。
In this paper,sites within the territory of Bohai kingdom were examined to analyze relationships between their spatial distribution and environment with GIS.The results showed that there was a preponderance of Bohai kingdom sites in China,followed by Russia and Korea.Settlements and cities on plains accounted for the greatest proportion among various sites,while other sites were relatively fewer.In Bohai kingdom,71.5% of sites were distributed within an elevation from 100 to 400 m where there were many low-lying and valley plains.With the increase in altitude,quantity of sites gradually decreases.Among different sites,plain cities,settlement sites,building sites and temple sites,etc.had smaller slope,whereas the slope was higher in other sites,and in particular the highest in sites of mountain cities.In 73.0%of Bohai kingdom sites,slope directed towards south,southwest,southeast,east and flat land where sunlight conditions were favorable,while there were very few sites where slopes were in other directions.65.9% of sites were within 600 mriver buffer zone.Beyond the range,the number of sites decreased gradually with the increase of distance,showing obvious attenuation regulation of distance.
