摘要
基于GIS手段分析2018年新疆沙化土地分布特征,从海拔、坡度、坡向因子等方面探讨新疆土地沙化发生的潜在原因和发展变化的主要驱动力。结果表明:新疆土地沙化程度有所减弱,总体上有所改善;新疆沙化土地海拔分布在500~1500 m范围内,坡度在0~6°范围内的缓坡是主要沙化区;就坡向而言,研究区阳坡方向土地沙化程度大于阴坡。研究结果可为新疆土地沙化防治提供数据支持。
Based on GIS technology,the distribution characteristics of desertification land in Xinjiang in 2018 were analyzed,and the potential causes of desertification and the main driving forces of development and change in Xinjiang from the aspects of altitude,slope and aspect were discussed.The results showed that the degree of land desertification in Xinjiang had weakened,and the overall trend was to improve.The desertified land in Xinjiang was distributed within the altitude range of 500~1500 m,and the gentle slope in the range of 0°~6°was the main desertified area.In terms of aspect,the degree of desertification in the sunny slope was greater than that in the shady slope.
