宋代长江沿线的农业开发与生态环境变迁

Agricultural Development and Ecological Environment Changes along the Yangtze River in the Song Dynasty

农业活动与生态环境息息相关。从环境因素看,气候条件、湖泊变化、土地资源是促使宋代长江沿线农业发展的重要条件。在生态环境的影响下,宋代长江沿线的农业活动表现出农业生产技术的提升、农作物新品种的引进、水利田的开发与应用等新特点,沿江的农业生产有了较为明显的提高和改进。与此同时,农业生产发展也给宋代长江沿线的生态环境带来了一些负面影响,如人地冲突加剧、水土流失频繁、土地质量损耗严重等。宋代长江沿线农业生产活动与生态环境之间呈现一种交互作用关系。

Agricultural activities are closely related to the ecological environment.From the perspective of environmental factors,climate conditions,lake changes,and land demand were important conditions that promoted the development of agriculture along the Yangtze River in the Song Dynasty.Under the influence of the ecological environment,the agricultural activities along the Yangtze River in the Song Dynasty showed new characteristics such as the improvement of agricultural production technology,the introduction of new crop varieties,and the development and application of water conservancy fields.The agricultural production along the Yangtze River had been significantly promoted and improved.At the same time,the development of agricultural production also brought some negative impacts to the ecological environment along the Yangtze River in the Song Dynasty,such as intensified human land conflicts,frequent soil erosion,and severe land quality loss.There was an interactive relationship between agricultural production activities and the ecological environment along the Yangtze River in the Song Dynasty.
