“…Consistent with the results of previous studies, this finding indicated that ERPs were successfully implemented in the study area [50]. Existing studies also found that afforestation considerably relieved land degradation due to the large conversion of desertification areas into forests [30,51]. Therefore, afforestation has become the dominant restoration activity that remarkably enhances vegetation cover in Southwest China.…”

Large-scale ecosystem restoration projects (ERPs) have been implemented since the beginning of the new millennium to restore vegetation and improve the ecosystem in Southwest China. However, quantifying the effects of specific restoration activities, such as afforestation and grass planting, on vegetation recovery is difficult due to their incommensurable spatiotemporal distribution. Long-term and successive ERP-driven land use/cover changes (LUCCs) were used to recognise the spatiotemporal patterns of major restoration activities, and a contribution index was defined to assess the effects of these activities on gross primary production (GPP) dynamics in Southwest China during the period of 2001–2015. The results were as follows. (1) Afforestation and grass planting were major restoration activities that accounted for more than 54% of all LUCCs in Southwest China. Approximately 96% of restoration activities involved afforestation, and these activities were mostly distributed around Yunnan Province. (2) The Breathing Earth System Simulator (BESS) GPP performed better than the Moderate Resolution Imaging Spectroradiometer (MODIS) GPP validated by field observation data. Nevertheless, their annual GPP trends were similar and increased by 12,581 g C m−2 d−1 and 13,406 g C m−2 d−1 for MODIS and BESS GPPs, respectively. (3) Although the afforestation and grass planting areas accounted for less than 1% of the total area of Southwest China, they contributed to more than 1% of the annual GPP increase in the entire study area. Afforestation directly contributed 14.94% (BESS GPP) or 24.64% (MODIS GPP) to the annual GPP increase. Meanwhile, grass planting directly contributed only 0.41% (BESS GPP) or 0.03% (MODIS GPP) to the annual GPP increase.

“…In the expansion stage (2016-2023), the words "forest ecosystem", "agricultural products", "ecological industry", and "ecological products" are the main trends in the control of KD, with a focus on breaking through the formation mechanism and process of derived ecological industries [27,45,52,[122][123][124]. Collaborative development of forest ecosystem services and ecological industries is conducive to balancing ecological remediation and economic development [125][126][127][128].…”

“…Synthesizing CNKI and WoS, before 2002, KD research comprised a discussion of basic theories, until Kangning Xiong's team published the first monograph on KD, which defined the concept of KD and classified it while revealing the driving and genetic mechanisms [9]. Since then, from 2002 to 2014, a large number of highly co-cited and highly central studies have appeared, a large number of them focused on key subjects related to the concept of KD, drivers, the human-land relationship, GIS technology, and control models [10,124,172,[176][177][178]. Research on the impact of natural and human factors on KD is highly popular, which forges an important research direction for KD.…”

Karst desertification (KD) is a major ecological and environmental problem threatening human survival and development in karst areas. In order to explore the research situation and development trend of KD based on forest ecology, this paper provides a systematic literature review based on the CNKI and WoS databases, which involves search, appraisal, synthesis, and analysis. We performed a statistical and visual analysis of 2955 studies acquired between 1 January 1995 and 30 June 2023, including the time distribution of the studies, hot research trends, pivotal research clusters, literature co-citations, main publishing trends, and keyword bursts. The results show the following. (1) The literature shows a fluctuating growth trend, and the research trends are divided into accumulation, development, and expansion stages. (2) The pivotal research clusters comprised three major aspects: study area and method, driving and genetic mechanisms, and control technology and models. (3) KD research forms a China-centered research network, dominated by institutions and scholars in southwestern China. (4) Future research needs to solve a series of related scientific issues and technological needs for forest ecosystem function optimization, ecological product supply capacity enhancement, ecological product value realization, ecological industry formation, and rural revitalization in KD control. The purpose of this paper is to reveal research trends relating to KD and highlight the future direction of KD research and control.

“…In addition, researchers have put forward specific measures and advice for rocky deserti-fication control from multiple perspectives, including geomorphology, geological structure, land use, rocky desertification grade and socioeconomic conditions (Bai et al, 2013;Sadeghravesh et al, 2016). Several effective control modes have been suggested, such as the Dingtan Pepper mode in the karst gorge area (Figures 4a and 4b), Puding mode in the karst peak cluster area (Figures 4c-4f), Liupanshui Sanbian mode in the karst tectonic basin area, Bijie Wuzidengke mode in the mid-to-high mountainous regions, Xichou mode in the karst valley area, Guohua stereoscopic agriculture mode in the peak cluster depression area and Tiandeng mode in the peak forest plain area (Du et al, 2019). These rocky desertification control measures share a common characteristic -they are designed to combine rocky desertification control projects (RDCPs) with PAPs, emphasising both ecological benefits and farmers' livelihoods.…”

Rocky desertification poverty (RDP) refers to rural poverty triggered or exacerbated by rocky desertification, which deprives farmers of opportunities for improving their financial conditions through agricultural production. As China implements strategies including building a moderately prosperous society, targeted poverty alleviation, and rural revitalization, issues concerning RDP have become the work foci for the Chinese government and research hotspots for Chinese academic circles. This paper provides a thorough review of the history, progress, challenges and prospects based on decades of RDP studies in Southwest China. First, we review the origin, definitions and historical development trends of RDP. Over nearly four decades, research on RDP can be framed as four stages: start-up, poverty alleviation and ecological reconstruction, rocky desertification comprehensive control and green development. We find that RDP research progress appears to be directly related to the Chinese government's policy support and decision-making in mitigating RDP. Second, previous findings are reviewed and summarised regarding four research aspects: relationship exploration between rocky desertification and rural poverty, mechanisms of rocky desertification for exacerbating poverty, strategies for eliminating RDP and anti-poverty benefit evaluations of rocky desertification control efforts. Third, the remaining challenges are identified and summarised, including the challenges of conducting theoretical research on RDP and consolidating achievements in eliminating RDP. We find that while many achievements have been made in the study of RDP in recent decades, the completeness and systematism of the theoretical system remain weak, and the guidance for empirical research is still insufficient. Finally, this research is fundamental in achieving rural revitalization in rocky desertification ar-
