摘　　要：安太堡煤矿是中国西北地区较大的露天煤矿,其排土场修复模式较为典型。本文基于GEE平台,查明了安太堡煤矿各排土场生长季平均植被降水利用率(rainfall utilization efficiency,RUE),并分析了其在人工管护、自然波动和自然稳定阶段的时空变化规律、变化稳定程度和变化趋势。研究表明:修复全周期中各排土场RUE值总体呈波动增加趋势,且增加趋势区域面积占比均大于87%;RUE变异系数均值均大于0.2,波动程度较大且高波动区域面积占比均大于99%。短阶段中各排土场RUE值逐渐增加,RUE高值范围不断扩大;内排土场、南排土场和西排土场RUE增加趋势区域面积占比、RUE变异系数值、高波动区域面积占比呈先减小后增大变化规律;西扩排土场以上指标一直减小仍需进一步监测。研究区恢复效果明显且证明了RUE应用于排土场修复监测的有效性。The antaibao coal mine is a relatively large open-pit coal mine in the northwest region of China,and its waste dump restoration model is relatively typical.This paper is based on the GEE platform to identify the average vegetation precipitation utilization efficiency(RUE)during the growing season of various waste disposal sites in antaibao coal mine,and analyze its spatiotemporal changes,degree of stability,and trend during the stages of artificial management,natural fluctuation,and natural stability.Research shows that throughout the entire repair cycle,the RUE values of each waste dump show an overall fluctuating and increasing trend,and the proportion of the increasing trend area is greater than 87%;the average coefficient of variation of RUE is greater than 0.2,with high volatility and high volatility areas accounting for more than 99%.In the short term,the RUE values of each waste dump gradually increase,and the range of high RUE values continues to expand;the proportion of area with an increasing trend of RUE in the inner,southern regions,and western regions,the value of RUE coefficient of variation,and the proportion of area with high volatility show a pattern of first decreasing and then increasing;the above indicators of the western expansion waste dump have been decreasing and further monitoring is still needed.In summary,the restoration effect of the research area is significant and proves the effectiveness of RUE application in monitoring the restoration of waste disposal sites.
