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,...
Following significant urban expansion, the ecological problems of resource-based cities are gradually exposed. It is great significance to study ecosystem services achieve their sustainable development goals and alleviate conflicts between environmental protection utilization surrounding resources. However, in current research on cities, few scholars have combined multiple minerals explore impact mineral resources ecosystem. In this study, based historical data spanning from 2002 2018, we...
Global climate changes have a great impact on terrestrial ecosystems. Vegetation is an important component of ecosystems, and the ecosystems can be determined by studying vegetation phenology. phenology refers to phenomenon periodic in plants, such as germination, flowering defoliation, with seasonal change during annual growth cycle, it considered one most efficient indicators monitor changes. This study collected global land surface satellite leaf area index (GLASS LAI) products,...
With the social and economic development in recent years, human activities have been more extensive intensified. As a result, ecosystems are damaged to varying degrees, regional ecological environments tend be weaker. The socio-ecological system Aba Prefecture, Western Sichuan Plateau, China, researched area, also faces increasingly serious problems. To advance civilization coordinated way across country, national government competent authorities launched series of new strategies. Research...
Landslides are common natural disasters that cause serious damage to ecosystems and human societies. To effectively prevent mitigate these disasters, an accurate assessment of landslide hazards is necessary. However, most traditional hazard methods rely on static factors while ignoring the dynamic changes in landslides, which may lead false-positive errors results. This paper presents a novel method for Zagunao River basin, China. In this study, updated inventory was obtained basin using...
Reservoir impoundment imposes a significant triggering effect on bank landslides. Studying the early identification of landslides and their stability concerning reservoir water levels rainfall is vital for guaranteeing safety residents infrastructure in regions. This study proposed method establishing dynamic inventory active at large hydropower stations using integrated remote sensing techniques, demonstrated Lianghekou Reservoir. We employed interferometric stacking synthetic aperture...
An Ms 6.8 earthquake struck Luding County, Ganzi Prefecture, Sichuan Province on 5 September 2022, with the epicenter about 10 km away from Hailuogou Glacier. How Glacier was affected by of major concern to society. Sentinel-1 SAR satellite imaging used monitor glacier surface velocity during different periods before and after based pixel offset tracking (POT) technology, which applies a feature-tracking algorithm overcome phase co-registration problems commonly encountered in large...
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...
The environment supplies water, land, biological resources, and climate resources for people’s daily life development, dramatically affecting the subsistence development of human beings. Panzhihua City is a representative resource-based industrial city southwestern China. abundant mineral provide material basis city’s development. However, while overdevelopment past decades has provided preconditions its rapid economic growth, it also inevitably had huge impact on environmental quality land...
The Upper Jinsha River (UJSR) has great water resource potential, but large-scale active landslides hinder development and utilization. It is necessary to understand the spatial distribution deformation trend of in UJSR. In areas high elevations, steep terrain or otherwise inaccessible humans, extensive landslide studies remain challenging using traditional geological surveys monitoring equipment. Stacking interferometry synthetic aperture radar (stacking-InSAR) technology, optical satellite...
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...
Problems caused by mining in resource-based cities, such as soil erosion and ecosystem imbalance, have impacted water supply stability. Given the relationship between resources yield, an in-depth study of yield(WY) services its driving forces reveals mechanism resource changes. This contributes to ecological restoration management areas, promotes sustained utilization. Seven typical cities with different characteristics China were selected for study. The InVEST model was employed numerical...
