| 摘 要： | 通过对渭干河-库车河三角洲绿洲土壤含盐量空间异质性及人为驱动力分析,结果表明:土壤含盐量在0-10cm、10-30cm和30-50cm具有一致的空间分布格局,在绿洲的东部、南部和东南部含量分布相对较高,绿洲西部和西北部的含量分布偏低,而在绿洲北部和西南部,土壤含盐量具有中等水平的空间分布。人口的增长以及人类不合理的经济活动致使绿洲部分区域受人为活动影响严重,灌区地下水位上升、土壤弃耕严重,致使盐分在土壤中急剧增加,表聚强烈。因此,改变不合理的经济增长方式,研究先进的农业种植技术,有效控制人口增长速度以及制定相应的盐渍化防治措施是目前渭干河-库车河三角洲绿洲急需解决的首要问题。

| Abstract: | We analyzed the spatial variability of the soil salt contents and the artificial driving influence in the delta oasis of Weigan and Kuqa rivers.The results indicated the soil salt contents in 0-10cm,10-30cm and 30-50cm layers have the similar spatial distribution pattern.The content distribution is relatively higher in the eastern,south and southeast area of the oasis;The content is low in the west and the east-north part of the oasis;The soil salt content has the medium level in the north and the west-north of the oasis.The population growth as well as humanity’s unreasonable economic activity seriously influenced the region;In the irrigation area subsoil water level rose,the land abandoned seriously,which caused salinity of the soil.The soil salt content gathered intensely on surface.Therefore,changing the unreasonable economic growth way,studing the advanced agricultural planter technology,actively controling population growth speed as well as the formulation corresponding salinification prevention measure are urgently needed to solute the problems in the delta oasis of Weigan and Kuqa rivers at present. |
