Assessment of fine-resolution land cover mapping products in the Changbai Mountain Range, China

All Earth (2024)

Longxue Zhao Xuanrui Liu Jue Xue Xiaoyi Guo Hongyan Zhang

Land cover data are essential for modelling land surface processes in mountainous regions. Fine-resolution land cover products have provided unprecedented spatial detail of the land surface. The performance of land cover classification can be affected by various causes, propagating uncertainty through modelling. In this study, six openly accessible fine-resolution land cover data products for 2020, namely GlobeLand30, CLCD, GLC_FCS30, Esri land cover, WorldCover, and DynamicWorld, were cross-compared for consistency and accuracy in the Changbai Mountain Range. The study particularly highlighted the consistency and accuracy across various geomorphic types. The findings reveal that all the six data products exhibit an overall similarity in spatial patterns dominated by cropland and forest. Validation using a ground reference dataset revealed that WorldCover and GlobeLand30 provide the highest and lowest accuracy, respectively. Cropland and forest present considerable spatial consistencies among the data products and advanced accuracies. The middle-mountain regions with low landscape diversity and fragmentation showed the highest consistency and accuracy. Data products, however, are difficult to represent the distribution of grassland, wetland, and bare ground categories reliably due to limited consistency and accuracy. This study provides quantitative analysis for selecting appropriate land cover data products towards application implementations.

Influence of different mining locations on deformation characteristics of overlying strata on gently anti-dip high-steep mining slope

Scientific Reports (2024)

W. Enge Jianjun Zhao Qiyi Lai Jianle Yu Jie Deng

High-steep gently inclined mining slopes, prevalent globally, often suffer significant deformation, leading to landslides due to numerous goafs. This research investigates the critical role of goaf location in controlling deformation, failure mechanisms, and disaster evolution, vital for safe mining practices. Through field investigations and model generalization in Guizhou, a physical model test method was used to study three positions of goafs: under the shoulder and foot of the slope, under the slope shoulder, and within the slope. Findings highlight the stronger influence of the goaf's mutual position with the slope shoulder on slope and overburden deformation and failure compared to the slope toe. Deformation and failure modes evolve from collapse toppling to collapse slip and collapse settlement as the goaf shifts from the near slope surface to inside of the slope. Statistical analysis of fracture distribution in the goaf's overlying strata reveals damage increase with larger goafs, following a Gaussian distribution, with concentrated damage in the middle. The study identifies the maximum damage area, influenced by the horizontal distance between the goaf center and slope shoulder. These insights advance understanding of overburden rock deformation in gently inclined high-steep mining slopes.

Analysis of an anti-dip landslide triggered by the 2008 Wenchuan earthquake in China

Natural Hazards (2013)

Runqiu Huang Jianjun Zhao Nengpan Ju Guo Li Min Lee Lee

The Guantan landslide, with a total displaced mass of about 468 × 104 m3, was triggered by the 2008 Wenchuan earthquake and succeeding rainfall in Jushui Town, Sichuan Province, China. The landslide occurred on an anti-dip hard rock slope with a weak rock founding stratum of 200 m in thickness. To investigate the failure mechanism of the Guantan landslide, dynamic behaviors of hard and soft rock slopes were investigated by means of large scale shaking table tests. The laboratory models attempted to simulate the field geological conditions of the Guantan landslide. Sinusoidal waves and actual seismic waves measured from the Wenchuan Earthquake were applied on the slope models under 37 loading configurations. The experimental results indicated that deformation mainly developed at a shallow depth in the upper part of the hard rock slope and in the upper (near the crest) and lower (near the toe) parts of the soft rock slope. An equation for predicting the depth of sliding plane was proposed based on the location of the maximum horizontal acceleration. Finally, it was concluded that the failure process of the Guantan landslide occurred in three stages: (1) toppling failure caused by compression of the underlying soft rock strata, (2) formation of crushed hard rock and sliding surface in soft rock as the result of seismic shocks, particularly in the horizontal direction, and (3) aftershock rainfall accelerates the process of mass movement along the sliding plane.

Study of distribution and development laws of secondary disaster in Longmenshan Area after earthquake

Yangtze River (2011)

Jianjun Zhao

In order to study the distribution and development laws of the secondary disaster in Longmenshan Area after Wenchuan earthquake on May 12th,2008,on the basis of remote sensing interpretation,combining with massive field investigation,we studied the relations between distribution and development laws of the secondary disaster in Longmenshan Area after earthquake and the geological factors including elevation,distance from fault,slope gradient,slope direction,lithology,structure of slope body,etc.in the basins of Jushui River,Anchang River,Mianyuan River and Shiting River.We summarize influential degrees of each geological factor on distribution and development of secondary disaster and the correlations between them.It provides important basic information for site selection,reconstruction in disaster area and projects of similar geological conditions.
