夏津黄河故道古桑树群聚生世存的历史成因

Historical Origins of the Accumulation of Ancient Mulberry Trees Group along the Ancient Yellow River in Xiajin

夏津黄河故道古桑树群是自然与人类互动的产物。历史上,夏津低强度的农业生产发展模式,不以“叶用”为主要目的的桑树种植选择,使得桑树群能够在一个较少人为干预的环境中任其展示自然生命力的韧性,并以“群”的规模聚生世存下来。夏津作为一个“疲邑亦瘠邑”的弱质农业区,在改变生存环境的持续斗争中,选择了植树造林这一最传统但也是治理成本最低的方法。桑树作为固堤治沙的所宜之木,也是黄河治理所需的重要堤防物资,又使得广植桑树在夏津实际成了一种生存策略选择。而地方循吏道德主义的劝课农桑,进一步刺激了夏津的桑树种植选择,从而为桑树群的聚生世存提供了一个有利的政治空间。

The ancient mulberry trees group along the ancient Yellow River in Xiajin is a product of interaction between nature and humans.In history,the low-intensity agricultural production development model of Xiajin,which did not focus on“leaf use”as the main purpose of mulberry tree planting selection,allowed mulberry clusters to demonstrate the resilience of natural vitality in an environment with less human intervention,and survived on a“cluster”scale.Xiajin,as a weak agricultural area that was both tired and barren,had chosen afforestation as the most traditional but also the lowest cost method of governance in the continuous struggle to change the living environment.Mulberry trees,as a suitable tree for reinforcing embankments and controlling desertification,were also an important material for the Yellow River control,making the widespread planting of mulberry trees a practical survival strategy choice in Xiajin.The moral persuasion of local officials to cultivate mulberry trees further stimulated the selection of mulberry tree planting in Xiajin,providing a favorable political space for the survival of mulberry trees.
