农牧交错带变迁的格局与过程及其景观生态意义

Change pattern,process and landscape ecological significance in ecotone of agriculture and grassland in north China

  • 摘要: 从景观生态角度出发研究了农牧交错带历史变迁的格局、过程、动力机制及其对区域农业发展的影响。阐述了我国农业发展与历史农牧界限的波动;农牧交错带气候变化与农牧业交替及农牧交错带的景观生态意义。秦汉以后农牧界限有限度波动和长城沿线农牧业交错变迁与区域内气候环境的干湿交替及农耕经济和游牧经济的此消彼长相对应。农牧交错带具有环境脆弱特征,在农业景观异质性的形成和流动输出及其对相邻区域农业技术发展的影响上表现明显作用。

     

    Abstract: Proceeding from landscape ecology, the change pattern, process, dynamic mechanism and effects on regional agricultural development in ecotone of agriculture and grassland in north China were studied. The agricultural development and the fluctuation of boundary of agriculture and grassland in china, the climatic change in ecotone of agriculture and grassland and the alternative replacement of agriculture and busbandry, and the landscape ecologic significance of ecotone of agriculture and grassland are expounded.The limited fluctuation of boundary of agriculture and grassland and the replacement of agriculture and husbandry alternatively were correspondent to the replacement of dry and wet climate and the growth and decline of farming and drift husbandry economics alternatively. In addition that the ecotone of agriculture and grassland has the fragile characteristics in environment, there was obvious heterogeneity formation and flowing out in agricultural landscape and their effects on agricultural techniques and development of adjacent regions.
