| 摘 要： | 通过查阅历史献和实地考察，对历史时期西北地区农业开发及对生态环境所造成的影响进行了探讨，并以新疆和河西走廓为例，重点分析了历史时期由于对楼兰，河西走廓等区域的不合理开垦，利用以及对森林的滥伐等，造成对当地河流移徙，土地沙化等严重后果，为了吸取这一历史教训，从生态环境的角度提出了在当今西北大开发中，应遵循自然规律，宜农则农，宜牧则牧，宜林则林，有效地保护生态环境。

| Abstract: | Based upon the historical materials and fieldwork.The northwestern agricultural development in history and its influence on ecological environment of the northwest are investigated.With Xinjiang and Hexi as two examples, the environmental problems are stressed in Loulan and Hexi, such as land desertification and river movements caused by the unreasonable use of land and deforestation.In order to draw a lesson from history and protect ecological environment effectively,it is suggested that we should follow the laws of natural environment and use land according to different soil qualities,some lands for farm, some for grass and others for forests. |
