摘 要:民国时期中国西南地区商品化农业的发展较前大为加快,其对自然生态的影响也较前更为明显。烟草、鸦片等是此时期西南商品化程度最高的农产品,对西南地区的经济发展、土地利用/覆盖均有较大影响。此时期西南地区现代化因素如工业化、城市化的加速发展,扩大了对粮食、工业原料等商品化农产品的需求,促使农业分布由传统中心区域向其他区域扩张,从而也成为刺激西部农业布局拓展进而推动生态变迁的一个重要因素。种种因素积渐所致,最终形成宏观的生态环境后果。During the period of the republic of China,commercialization of agricultural development in its southwestern regions was greatly sped up than before,which also produced more obvious effects on the natural ecology.Tobacco, opium,etc.are the most commercialized agricultural products in this period in its southwestern regions,and all have great influence on the region's economic development,land use and forest coverage.In which period,the modern factors such as industrialization and the acceleration of urbanization development,expanded the demand of commercialized agricultural products such as food,industrial raw materials and so on,prompting its agricultural distribution from the traditional central region to other areas,thus become an important factor to spur the western agricultural layout expansion and caused its ecological change.As a result,various such caused factors,gradually,and finally form the macroscopic ecological consequences.
