摘      要：Retrospectively evaluating the efficacy of revegetation practices is helpful in planning and imple-menting future ecosystem restoration programs(ERP).Having a good understanding of how human activities can affect vegetation cover,both before and after ERP,is particularly important in sandstorm hotspot *** Beijing-Tianjin Sandstorm Source Region(BTSSR)is one such *** conducted an investigation into vegetation dynamics within the *** was done using remote sensing data in conjunction with climate data sets and land use data spanning the 1982-2014 *** relationships between climatic factors(such as precipitation and temperature),and vegetative change were modeled using a neural network *** a process of residual analysis,the proportions of human-induced vegetative change both before and after the ERP were *** results show that:1)before the ERP(1982-2000),40.96%of the study area exhibited significantly progressive vegetation changes(p0.05).This proportion decreased to encom-pass only 20.23%of the study area in the period following the ERP(2001-2014).2)89.55%of the study area showed signs of human-induced vegetation degradation before the *** 2001 and 2014 however,following ERP,this figure fell to only 27.78%.3)ERP implementation led to visible improvements in vegetative conditions within the BTSSR,especially in areas where ecological restoration measures were directly and anthropogenically *** results highlight the benefits that positive human action(i.e.,revegetation initiatives implemented under the framework of an ERP)have brought to the BTSSR.
