The Three Gorges Reservoir region in China is the Yangtze River Economic Zone’s natural treasure trove. Its environment has an important role development. unique and fragile ecosystem River’s prone to disasters, including soil erosion, landslides, debris flows, earthquakes. Therefore, better alleviate these threats, accurate comprehensive assessment of susceptibility this area required. In study, based on collection relevant data existing research results, we applied machine learning models,...
Panzhihua City is a typical agricultural-forestry-pastoral and ecologically sensitive city in China. It also an important ecological defense the upper Yangtze River. has abundant mineral resources, including vanadium, titanium, water supplies. However, environmental problems emerge due to excessive development of mining, agriculture, animal husbandry, other non-natural urban economies. Therefore, scientific understanding spatio-temporal changes eco-environment critical for protection,...
Global CO2 concentration has become a key driver of climate change, influenced by both anthropogenic emissions and natural carbon cycles. However, due to the spatiotemporal heterogeneity sources sinks, estimating flux remains highly uncertain. Accurately quantifying contribution various sinks atmospheric is essential for understanding cycle global balance. This study utilizes GEOS-Chem model, driven MERRA2 meteorological data emission inventory data, simulate monthly concentrations from 2006...
Abstract With the drastic change in global climate, wide distribution of natural lakes over Qinghai-Tibet Plateau (TP) has attracted extensive attention due to their high climate sensitivity. In this paper, we investigated dynamics Paiku Co, largest inland lake Qomolangma Natural Reserve, with associated response past three decades. The methods used contain water index method, spatial and temporal fusion model, statistical mono-window algorithm, multi-variable linear regression. Lake area...
Glacial lakes are important freshwater resources in southern Tibet. However, glacial lake outburst floods have significantly jeopardized the safety of local residents. To better understand changes response to climate change, it is necessary conduct a long-term evaluation on areal dynamics lakes, assisted with observations. Here, we propose an innovative method classification and stacking extraction accurately delineate southwestern Tibet from 1990 2020. Based Landsat images meteorological...
Improvements in hyperspectral image technology, diversification methods, and cost reductions have increased the convenience of data acquisitions. However, because their multiband multiredundant characteristics, processing is still complex. Two feature extraction algorithms, autoencoder (AE) restricted Boltzmann machine (RBM), were used to optimize classification model parameters. The optimal was obtained by comparing a stacked (SAE) deep belief network (DBN). Finally, SAE further optimized...
The Yellow River Basin in China has the world's most serious soil erosion problem. Sichuan Province (YRS), as upper reaches of River, and its water conservation (WC) capacity greatly affects ecological environment downstream basin. In recent years, YRS received more attention, numerous policies have been developed to improve local WC. However, there is a vacancy long-term research WC due lack in-situ data. This study quantitatively evaluated from 2001 2020 through Google Earth Engine (GEE)...
Lakes are important natural resources closely related to human survival and development. Based on PIE cloud computing platform, the study uses Landsat images empirical normalized water body index (ENDWI) extract information of large lakes in Sichuan province from 2000 2020 drought rainy seasons, respectively, Mann–Kendall test obtain long-term trends their area climate. On this basis, evolution correlation with climate activities analyzed. The results show that (1) In past 20 years, Lugu...
Abstract The Sichuan-Tibet region of China has always been an area with frequent earthquake disasters, accompanied by the occurrence and collapse dammed lakes. lakes seriously threatens lives property safety downstream personnel. At same time, domestic foreign scholars are concerned about surrounding lake there few ecological studies on lake, impact ecology very important enlightenment significance for our construction project. It is purpose this article to scientifically predict risk dam...
