关于明清以来北方农牧交错带的环境变迁,学术界曾对于沙漠化的成因和人类在沙漠化进程中的作用进行论证,并引起过热烈的讨论。其中,人类活动被视为引起农牧交错带环境变化的主要因素。本文结合田野考察、发掘民间文献,分析以怀远县伙盘地为代表的蒙陕农牧交错带边外垦殖和环境变化过程,对环境变化中的人类因素加以细致考察与反思,认为清代以来,人类作为自然—社会系统中最活跃的因素,相当积极地参与了环境变化过程。此一阶段的人类活动(边外垦殖为主),促成了农牧交错带的北移、错位,也推进了土地沙化的进程。
Since the Ming and Qing Dynasties, the environmental changes in the ecotone between agriculture and animal husbandry in northern China have demonstrated that the causes of desertification and the role of human beings in the process of desertification have been argued by academics and led to overly heated discussions. Among them, human activities are regarded as the main factors that cause environmental changes in the ecotone between agriculture and animal husbandry. Combining with the field investigation and excavating the folk literature, this paper analyzes the process of reclamation and environmental change along the border between agriculture and animal husbandry in Huayuan County, and makes a detailed survey and reflection on the human factors in the environmental change. Since the Qing Dynasty As human beings, the most active factor in the natural-social system, human beings have taken a very active part in the process of environmental change. Human activities at this stage (mainly reclamation outside the border) contributed to the northward shift and dislocation of the ecotone between agriculture and animal husbandry, and promoted the process of land desertification.
