With the exploitation of rare earth elements (REE) in southern China, desertification has become a serious ecological problem in this region. To accurately understand the desertification process in mining areas and formulate targeted ecological restoration programs, taking the Lingbei mining area in Ganzhou City, Jiangxi Province as the study area, we explored desertification information extraction methods, desertification dynamics monitoring, and desertification drivers in REE mining areas using multisource data from 1986 to 2021. The results show that from the method of extracting desertification information, Random Forest is the prominent (83.33%), followed by Albedo–NDVI (Normalized Difference Vegetation Index) space (74.44%), and thirdly Linear Spectral Mixture Model (65.56%). From 1986 to 2021, the desertification land area in Lingbei mining areas first increased and then decreased, showing a reverse trend, but it has not recovered to the pre‐mining level. The government's ecological reclamation measures are the key factors for the restoration of desertification land. There are still 17.81 km2 areas that have not been restored, of which 2.16 km2 are at the level of severe desertification. Moderate desertification and light desertification have not been completely curbed, which needs continuous attention. Vegetation coverage has the highest explanatory power to the distribution of land desertification in mining areas, followed by land use classification, indicating that human activities have a great influence on the spatial differentiation of land desertification in mining areas, and it is necessary to pay attention to regional balanced and sustainable development in the future.

Objective: Our aim was to evaluate the effectiveness of a modified 8-week reminiscence therapy on the burden, positive experience, and life satisfaction of older spouse caregivers and the life satisfaction of stroke survivors.Methods: We conducted a randomized controlled trial by using 75 older stroke couples recruited from communities in Zhengzhou, China. We randomly assigned participants to 1 of 3 groups: Group 1 (G1 , 25 couples, all attend intervention) and Group 2 (G2 , 22 couples, only caregivers attend intervention), who participated in a modified 8-week reminiscence therapy, and a waiting list (control) group (G3 , 28 couples). Interviewers blinded to treatment group assignment administered the life satisfaction to both stroke survivors and caregivers, caregiver burden, and positive experience for caregivers, at preintervention, immediately postintervention, and at 1 month and 3 months after cessation of the intervention.Results: We found a statistically significant interaction between treatment groups and assessment time points for the 4 outcome measures (P < .001). Although the effects were decreased after intervention at 1 month, the improvement in caregivers' positive experience, life satisfaction, burden, and life satisfaction of stroke survivors were still significant (P < .001).Conclusions: The use of a modified 8-week reminiscence therapy in this study sample improved the life satisfaction of stroke survivors and their spouse caregivers, improved the positive experience of caregivers, and decreased the burden of caregivers.
