| 摘 要： | 土地是一种最基本的生产资料 ,是人类进行一切生产活动赖以生存所必须的物质基础。新疆土地资源量在我国具有比较大的优势 ,但是 ,在新疆的土地利用开发过程中 ,由于我们人类作用于自然 ,改变自然生态系统为人工生态系统 ,其相互关系是十分复杂的。 2 0世纪 5 0年代以来 ,随着耕地面积的急剧扩大与对土地不合理的利用 ,致使土地退化日趋严重。再加上不合理的开垦及对植被的破坏 ,使生态失去平衡。新疆属干旱地区 ,生态环境脆弱 ,人类经济活动干预是短期内变化的主导因素 ,结果给河流、湖泊、土壤、植被以及沙漠都带来了很多不利影响 ,必须寻求对策加以解决。

In addition, unreasonable cultivation and destruction to vegetation,it Makes the ecology lose balance. Xinjiang belongs to the arid area, The ecological environment is fragile, It is a leading factor that an ecological environment is changed shortly that the human economic activity is intervened, The result has all brought a lot of adverse effects for the river, lake, soil, vegetation and desert and Has changed relatively greatly. |
