摘要: 以浙江省为例,基于地形特征及其形成、人口演变与土地开发、水利建设与农业技术发展等的历史变化分析,探讨了现代水耕人为土形成的年代。分析认为,虽然研究区水稻种植已有7 000 a左右的历史,但规模化水稻种植的历史基本上在2 000 a内。先秦以前,农业技术发展水平较低,难以形成大规模的稻田土壤水旱交替的环境,植稻土壤缺少现代水耕人为土的诊断特征。唐宋、明清和20世纪50—70年代是研究区水耕人为土形成的3个主要时期,水耕人为土面积迅速扩大。洪积扇和河谷平原地区可能是研究区内最早形成现代水耕人为土的主要区域。不同地貌区间大面积的水耕人为土的形成时间顺序大致为水网平原、河谷平原早于滨海平原早于丘陵山地。研究认为,稻作环境改善是现代水耕人为土形成的前提,农作技术发展和人口增加是水耕人为土面积扩大的主要动力。

Abstract: In the present study, Zhejiang was selected as the study area. Based on the analysis of the topography characteristics and its formation, the histories of population evolution and land development, water conservancy construction and development of agricultural technology, the formation age of modern Stagnic Anthrosols was discussed. According to the analysis, rice cultivation in the study area had been around for 7 000 years, but the history of large-scale rice plantation was basically in 2 000 years. Before the Qin Dynasty, the development level of agricultural technology was relatively low, so it was difficult to form a large-scale flood and drought alternation soil environment, and the soils were lack of diagnostic characteristics of modern Stagnic Anthrosols. The Tang and Song, Ming and Qing dynasties and the 50s to 70s of 20th Century were the three main forming stages of the Stagnic Anthrosols in the study area, and the area showed rapid expansion in these ages. Alluvial fan and valley plain might be the main distribution areas of the earliest modern Stagnic Anthrosols in the study area. The formation time of large area of Stagnic Anthrosols in the different landscapes was generally in sequence of water-net plain, river valley plain, coastal plain and hilly land. It was considered that the improvement of rice plantation environment was the precondition for the formation of the modern Stagnic Anthrosols, and the development of farming technology and the increase of population were the main motive forces for the expansion.

Key words: Stagnic Anthrosols, formation age, land development, rice plantation environment
