“…In terms of plant selection, native plants should be preferentially selected to enhance the stress resistance of plants [19]. Taking a variety of measures to repair the platform can effectively increase the final repair effect of the platform and ensure the long-term stable growth and development of the plant [20].…”

In recent years, most of the quarry sites are located in the periphery of the city, and for the convenience of transportation, they are generally close to traffic arteries and residential areas. When encountering severe weather, disasters such as landslides, mudslides, dust and sand will occur. The life safety and health of residents have caused adverse effects. Therefore, the development of researches suitable for paste-filling mining of metal mines in stone ore traces has important guiding significance for the smooth implementation of ecological restoration of stone mines. This paper takes the discrete mine paste network model as the research object, and studies the mineral degradation and influencing factors in the central and northern grasslands, the loess plateau, the southwest mountain and hilly area, and the northwest arid area of the western metal mining area, and then mining through the metal mine paste filling numerical simulation analyzes the repair of geological damage caused by paste filling technology. The research results show that the extremely severely damaged area in open-pit mines accounts for an average of 56.44% of the area, which is much larger than 5.61% of the underground mines. The mineral damage caused by mountain paste filling mining can be repaired in time. The sudden increase in the damaged area usually reduces the non-damaged area and increases the extremely severely damaged area. However, during the research period, as coal mining expands outward, there is a phenomenon that the non-damaged area increases and the extremely severely damaged area decreases.

“…The normalized difference vegetation index (NDVI) is widely used to study the spatiotemporal evolution trends of vegetation cover because it can eliminate most of the radiation errors caused by instrument calibration, solar angles, terrains, cloud shadows and other factors, giving it strong vegetation response ability [7][8][9][10][11]. Relevant studies show that hydrothermal conditions and vegetation types differ in different regions.…”

NDVI-Based Assessment of Land Degradation Trends in Balochistan, Pakistan, and Analysis of the Drivers

Land degradation destroys human habitats, and vegetation is a marker reflecting land degradation. In this article, the Balochistan Province of Pakistan, which has a fragile ecological environment, was selected as a typical case to analyze its land degradation over 21 years. Relevant studies that used the NDVI and remote sensing data to monitor land degradation already existed. Based on the data product of MODIS, this study obtained the spatio-temporal trends of the normalized difference vegetation index (NDVI) changes from 2000 to 2020 using the sen+ Mann–Kendall (MK) test and Hurst index and analyzed the driving factors of land degradation and restoration by employing the multiple stepwise regression method. The residual analysis method was an effective tool for distinguishing between anthropogenic and climatic impacts, given that not all regions have a significant correlation between the NDVI and rainfall. The main climatic drivers of the NDVI were derived based on the Geodetector analysis and stripped of the main climatic factors by residual analysis to explore the influence of anthropogenic factors on the NDVI. The results show the following: (1) Balochistan is dominated by land restoration. Land restoration is mainly dominated by climate as well as both climate and human factors, and land degradation is mainly dominated by climate and human factors. (2) The Geodetector-based study found high correlations between the NDVI and TMP, MAP, AET and PET, complementing most previous residual analyses that considered only precipitation and temperature. In Balochistan, TMP, AET, PET and MAP were the dominant climatic factors affecting the spatial distribution of the NDVI; TMP with MAP and TMP with AET were the main interactive factors in the spatial distribution of the NDVI. (3) The article quantifies the impact of the anthropogenic drivers on land degradation. Human activities positively influenced the NDVI in 91.02% of the area and negatively influenced it in 8.98% of the area. (4) The overall trend of the NDVI was mainly stable, with stronger improvement than degradation, and showed strong persistence. The above findings enrich our understanding of the climatic impacts of land degradation and human impacts in arid or semi-arid regions and provide a scientific basis for ecological engineering to achieve ecological conservation and quality development in Balochistan, Pakistan.
