ABSTRACT Saline soil is an important inorganic carbon pool and highly susceptible to environmental change. The Tarim Basin the largest inland basin around world, with saline land making up approximately 20% of its total area, while few research has been conducted on salt‐affected density distribution in region. To identify effect salinity density, we collected 135 profiles (0–100 cm), calculated organic (SOCD), (SICD), (STCD) their distribution, discussed relationships climate...

Abstract Opencast coal mining has a large impact on the land surface, both at pits themselves and waste sites. After artificial management is stopped, reclaimed opencast mine dump affected by wind water erosion from natural processes, resulting in degradation even safety incidents. In this paper, soil after 5 years of such Xilinhot Inner Mongolia, were investigated. A multi-source data acquisition method was applied: vegetation fraction coverage (VFC) extracted GF-1 satellite imagery,...

Abstract Global food security is being threatened by the reduction of high‐quality cropland, extreme weather events, and uncertainty supply chains. The globalization agricultural trade has elevated diversification non‐grain production (NGP) on cultivated land to a prominent strategy for poverty alleviation in numerous developing nations. Its rapid expansion engendered multitude deleterious consequences both ecological stability. NGP China becoming very common process urbanization,...

Abstract Eco-city construction is a powerful method which can advance city from traditional industrial civilisation to ecological civilisation. The of Huaibei, with 50 years coal mining history, has been listed as national resource-exhausted city. city's sustainable development and restoration work face severe challenges. This study presents time-space evolution analysis subsidence show the distribution area in Huaibei. Intensive use was made land evaluation formulate measures. According...

Elevation gradient is a key environmental factor influencing the distribution of plants in Gobi region. It can indirectly regulate based on terrain and varying soil moisture, nutrient distribution, particle composition. Undertaking ground vegetation surveys to observe over large scales region challenging due harsh environment manpower constraints. In addition, sparse region, precision parameters extracted from satellite remote sensing images low. Using spatial-point pattern analysis method...

Shrublands are the main vegetation component in Gobi region and contribute considerably to its ecosystem. Accurately classifying individual shrub species understand their spatial distributions effectively monitor diversity ecosystem is essential. High-resolution remote sensing data create type inventories over large areas. However, high spectral similarity between shrublands surrounding areas remains a challenge. In this study, we provide case study that integrates object-based image...

Coal bunkers are relatively closed systems. Due to their own oxidation characteristics and the increase of temperature, spontaneous combustion will occur beyond period. Moreover, coal is a disaster caused by multifield coupling, so it imperative carry out inerting fire prevention extinguishing. Based on this fact, combined with actual situation in Huanghua Port, paper establishes two-dimensional geometric model bunker, selects CO2 as inert gas sprayed determines position port bunker hopper,...

Shrubs are an important part of the Gobi Desert ecosystem, and their aboveground biomass (AGB) is manifestation productivity ecosystem. Characterizing biophysical properties low-stature vegetation such as shrubs in via conventional field surveys satellite remote sensing images challenging. The AGB had been estimated from spectral variables taken high-resolution obtained by unmanned aerial vehicle (UAV) Desert, Xinjiang, China, using feature metrics. main results were follows: (1) Based on...

When the location and intensity of source an explosion are determined, severity impact can be analyzed predicted, such as overpressure, temperature, toxic gas propagation. Determining also provide a theory for emergency rescue work, improve efficiency, ensure safety personnel. Therefore, through field data inversion great significance. Based on genetic algorithm (hereinafter GA) to back propagation (BP) neural network theory, roadway were inverted experiment simulated overpressure data. all...

The simulation of vegetation dynamics is essential for guiding regional ecological remediation and environmental management. Recent progress in deep learning methods has provided possible solutions to simulations. gated recurrent unit (GRU) one the latest algorithms that can effectively process dynamic data. However, static data, which typically coexist datasets changes, are processed indistinguishably. To efficiently extract spatiotemporal patterns improve our ability simulate potential we...

The increasing global population is leading to a decline in cropland per person, aggravating food security challenges. implementation of land consolidation (LC) has created new farmland and increased productivity. LC critical strategy China for ensuring gaining significant government support. This article investigates the impact on productivity Sichuan Province 2020. We utilize time series remote sensing data analyze LC’s capacity. study uses Sentinel Landsat satellite calculate CumVI...

Plots were set on the top, middle and bottom of stony desert alluvial fan in southern foothills Tianshan Mountains. With plant height crown size as indicators, spatial heterogeneity Ephedra przewalskii populations studied using geostatistical methods. Understanding characteristics E. could provide scientific basis for vegetation protection ecological restoration deserts. The results showed that had a patchy distribution at top fan. At fan, it banded distribution. band width was larger than...

Abstract Open-pit coal mining has a large impact on land surface, both at the pits themselves and waste sites. After artificial management is stopped, reclaimed opencast mine dump affected by wind water erosion from natural processes, resulting in degradation even safety incidents. In this paper, soil after 5 years of such Xilinhot open pit Inner Mongolia, were investigated. A multi-source data acquisition method was applied: vegetation coverage index extracted GF-1 satellite imagery,...
