摘要
汉代与春秋战国以来同属一个温暖期 ,这一历史时期气候的相对温暖与湿润 ,带来了丰富的水资源 ,并使土壤与植被都处在良好的自然循环状态。汉代农业的发展状况 ,诸如农作物布局的变化、农产量的提高以及农业经营方式特色的形成都与之息息相关。
Warm climate features the Han Dynasty.The relatively higher degree of temperature and humidity makes possible the abundant water supplies and in turn ensures the soil and aegetation to be in a better natural cycling state.The agricultural progresses witnessed by these periods,such as the adjustments made in the overall distribution of agricultural production,the increase in agricultural output and the distinctive agricultural operating style,are all the natural outcome of this warm-climate period.
