The serious problem of soil erosion not only has a profound impact on people’s lives but also results in series ecological and environmental challenges. To determine the changes land use type urban agglomeration northern slopes Tianshan Mountains, this study commences by employing InVEST-SDR (integrated valuation ecosystem services tradeoffs–sediment delivery ratio) model to calculate levels spanning from 2000 2020. Subsequently, it forecasts cover (LULC) conditions for year 2030 under three...

Abstract In this study, we identified heat index‐based spatiotemporally contiguous heatwaves (HI‐STHWs) in China based on meteorological observations and Coupled Model Intercomparison Project Phase 6 global climate model simulations. We analyzed the spatiotemporal patterns of changes HI‐STHWs past future quantitatively attributed these to anthropogenic activities. The results show that duration, severity, average, maximum, total impacted area annual strongest during present period 1991–2014...

A remote online carbon dioxide (CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) concentration monitoring system is developed, based on the technologies of wireless sensor networks, in allusion to gas leakage requirement for CO capture and storage. The consists equipment, a data center server, clients. equipment composed central processing unit (CPU), air environment sensors array, global positioning (GPS) receiver module, secure...

Aiming to provide a scientific basis for the prevention and control of soil erosion in Huaihe region, this study uses InVEST-SDR model estimate temporal spatial changes conservation region 2010, 2015 2020, driving factors are evaluated quantified using Random Forest Geodetector, respectively. The major findings as follows: (1) From 2010 loss retention gradually intensified, while distribution trend was consistent from year year. (2) results Geodetector show that mainly influenced by slope...

Automatic identification systems (AIS) provides massive ship trajectory data for maritime traffic management, route planning, and other research. In order to explore the valuable characteristics contained implicitly in AIS data, a clustering method based on resampling enhanced BIRCH (Balanced Iterative Reducing Clustering using Hierarchies) algorithm is proposed. The has been tested 764,393 points of 13,845 ships waters Taiwan Strait China, 832 trajectories have generated clustered obtain...

Industry is widely valued as an important contributor to carbon emissions. Therefore, it of great significance analyze the industrial emissions (ICE) in Guangdong, strongest province China. We have adopted emission accounting model and standard deviational ellipse analysis temporal spatial characteristics evolution trends industry amount intensity Guangdong from 1998 2013. The study results include: (1) Due rapid development industry, Guangdong’s ICE showed a steady growth trend; (2)...

Capital plays a crucial role in driving rural sustainable development. Some areas have achieved revitalization through capital intervention, while others experienced failure. It is possible that the purposes of intervention initiated by different parties (such as government, enterprises, and individual investors) differ, which leads to divergence development routes effectiveness. Yet, questions why how this phenomenon occurs not been well studied. Based on observation an in-depth interview...

As one of the 19 key regions for comprehensive land development in China, Tianshan North Slope urban agglomeration is significant China’s when calculating subsidence and analyzing impact factors. This study focused on eight cities agglomeration, rate from 18 January 2018 to 12 April 2023 using Sentinel-1A data spatiotemporal patterns factors subsidence. The results showed that (1) average mainly distributed between −30 10 mm/a, maximum can reach −358 mm/a. Land uplift occurs Hutubi County...

The northern slope of the Tianshan Mountains city cluster (NSTM), as a key urban agglomeration for development western China, has experienced rapid regional economic and high population concentration since twenty-first century. Accompanied by increase in human activities NSTM, it significantly altered land use structure, leading to varying levels habitat disturbance degradation. In this paper, based on cover (LULC) NSTM from 2000 2020. InVEST model was employed assess quality, revealing...

As a world-class urban agglomeration, the Yangtze River Delta agglomeration is significant for China’s carbon neutrality strategy when calculating budget and dividing compensation zones. This paper focused on 129 county-level cities in core area of 2000–2020 using night-time light data analyzing evolution spatiotemporal patterns. On this basis, zoning model was constructed K-means algorithm; were divided into different zones after combining with main functional The results showed that (1)...

Currently, there lacks real-time, effective, and highly sensitive means to monitor control Methane emissions in coalmining region. And the related principles, methods technology are not complete yet. With regards this point, of remote sensing circumstance region is expected have some advantages which other can match. This paper takes southern Qinshui basin Shanxi province as key research object. Then, best band chosen methane based on basic theory sensing, such that model spectral response...

For the poor condition of accessibility and varied deposition tidal beach, basic information such as topography is hard to be retrieved, it difficult monitor change beach. This paper takes flat muddy area east beach in Chong ming Shanghai typical research area, Land sat TM image relevant data primary source. Based on observed data, this analyzes spectral feature main vegetation ming, coupling extracts by using Normalized Difference Vegetation Index (NDVI) distribution retrieved resources...
