摘要
秦汉暖湿期农业文化向北扩展是顺应干预型的综合开发,有其合理因素。阴山南麓,河套冲击平原,鄂尔多斯黄土高原相对适宜的生存条件和气候环境,决定了土地利用方式的变化。青藏高原隆升,引起北方干旱和地质时期沙漠的形成、发展。第四纪环境是形成荒漠化的基础。临戎、三封、窳浑三城所在的乌兰布和北部古绿洲消亡的直接原因,可能与黄河干流改道有关。秦汉时生产力相对低下,处初垦状态,人类活动并没有对当时的生态环境构成威胁。其影响不应过于夸大。
For the duration of warmth and moisture of the Qin and the Han periods, farming culture advancing north conformed to the comprehensive intervention-type development, having its reasonable factors. The relatively appropriate living conditions and climatic environment at the southern foot of Yinshan Mountain, on the alluvial plain of the Great Bend of the Huanghe River and in the Ortos Loess Plateau decided on the changes of land utilization. The swell of Qinghai-Tibet Plateau resulted in northern drought and the desert formation and the development in the geological period. While the environment of the Quaternary Period was the basis of the formation of wilderness, the direct reason why the oases of the cities of Linrong, Sanfeng, and Yuhun disappeared in the northern part of Wulanbuhe had something to do with the course change of the Huanghe River. Productive forces being relatively lower in the Qin and the Han periods and being in original cultivation, the human activities didn＇ t constitute a threat against the ecological environment then, so we should not exaggerate its influence.
