摘要
为研究准东矿区土壤湿度时空分布特征及变化趋势,选取2001—2021年11期的Landsat遥感影像,计算归一化植被指数和地表温度,并以NDVI-LST特征空间为基础构造TVDI模型,反演准东矿区土壤湿度并进行分级,得到准东矿区各级土壤湿度面积,并采用灰色预测GM(1,1)模型对土壤湿度分布进行了预测。结果表明:2001—2021年,准东矿区总体土壤湿度较低,以四级和五级土壤湿度为主,两者面积总和占矿区总面积的85%以上;北部和东部区域土壤湿度较高,中部和西南部区域土壤湿度较低;矿区内一级、二级、三级土壤湿度面积年际变化不大,在0~2000km2波动;四级、五级土壤湿度面积变化表现出互为相反趋势。灰色预测GM(1,1)结果表明:2023—2039年,在0~1000km2内,一级土壤湿度面积略有增大,二级土壤湿度面积逐渐减小并趋于0,三级土壤湿度面积逐年下降,四级土壤湿度面积呈现逐年上升趋势,五级土壤湿度面积稳定在3000km2左右,表明该矿区土壤湿度整体呈减小趋势。

Abstract
In order to investigate the spatial and temporal distribution characteristics and the variation trends of soil moisture2023 to 2039, the grade 1 area of soil moisture will increases slightly within the range of 0 km2 to 1 000 km2, the grade 2 area of soil moisture will gradually decrease and tends to 0 km2, the grade 3 area of soil moisture will decrease annually, the grade 4 area of soil moisture shows an increasing trend, and the grade 5 area of soil moisture stays stable at about 3 000 km2. This indicates an overall decreasing trend for soil moisture in this mining area.
