塔里木河流域耕地动态变化分析—以阿克苏地区为例

Dynamic Change of Cultivated Land in Tarim River Basin-Taking Aksu Region as an Example

以阿克苏地区2010、2015和2021年三个时期的卫星影像数据为数据源,利用空间分析技术提取不同时期阿克苏地区耕地变化数据,并利用耕地动态变化度对不同时期研究区耕地动态变化情况进行分析。结果表明,阿克苏地区耕地总量自2010年至2021年整体呈增加趋势,其中阿克苏地区西部绿洲区耕地数量增长程度小于东部绿洲区;除库车县和沙雅县外,全区2010—2021年不存在耕地大量增加或耕地快速减少的情况。

With the satellite image data of Aksu region in 2010,2015 and 2021 as the data source,the cultivated land change data of Aksu region in different periods are extracted by using spatial analysis technology,and the cultivated land dynamic change degree is used to analyze the cultivated land dynamic change in the study area in different periods.The results showed that the total amount of cultivated land in Aksu region showed an overall increasing trend from 2010 to 2021,and the growth degree in the western oasis region was less than that in the eastern;Except for Kuqa County and Shaya County,there was no significant increase or rapid decrease of cultivated land in the whole region from 2010 to 2021.
