AB  - In this study we compared materials from less investigated badland sites in Turkey and China. Critical composition in badland material is the presence and ratio of the clay and silt size particles, clay mineralogy and presence of mobile ions, especially anions. In analyzed materials the presence of smectite governed the formation of surface crust. Surface cracks enabled ion leaching and became preferential paths from sediment movement. Critical composition in badland material is the presence and ratio of the clay and silt size particles and poor sorting. Sulphate and carbonate ions proved to be crucial for surface processes on these materials. Summarizing results it can be concluded that erodibility of badland lithologies is a combination of clay type, silt content and ion concentration.

AB  - Climate variables including temperature, rainfall intensity, rainfall acidity, and lithological properties are among the most important factors affecting rock weathering. However, the relative contribution of these four factors on rock weathering, especially on chemical weathering, is still unclear. In this study, we carried out a series of weathering-leaching rainfall simulations on four types of badland sediments under controlled conditions of two levels of temperature, rainfall intensity, and rainfall acidity based on the real field data from representative weather scenarios. The main objectives are 1) to explore the progressive change of sample surface and leachate characteristics and 2) to reveal the independent effects of temperature, rainfall intensity, rainfall acidity, and lithology and their relative contribution as well, on both mechanical and chemical weathering. Qualitative analysis on crack development and fragmentation of sample surface and quantitative analysis on the leachate volume, pH, electrical conductivity, and total cation and anion releases of sample leachate together demonstrated that for the investigated sediments, under the conditions of temperature, intensity, and acidity of rain that can be achieved in nature, high drying temperature obviously increases mechanical disintegration by promoting the rate and magnitude of moisture variations (wetting–drying alterations), while high rainfall intensity and acid rain have no obvious effect. Impact and importance of the drying process caused by high temperature between wetting events need more attention, rather than high rainfall intensity. Low temperature, high rainfall intensity, and acid rain contributing more hydrogen ions required for cation exchanges, rock type with more soluble minerals, all promote chemical weathering, and the influence of climatic and lithological factors on chemical weathering decreases in the following order: mineral composition＞ rainfall intensity ＞ temperature ＞ rainfall acidity. Climatic variations on temperature can modify weathering processes and in that way conditioned hydro-geomorphological processes in badland areas. Such changes should be considered for direct and indirect implications on badland dynamics.

AB  - To explore the impact of temperature difference (TD) on the disintegration of redbed softrock, three types of redbed rock, collected from Nanxiong Basin, were analyzed under three different treatments: TD, wetting and drying (WD), and TDWD-temperature difference and WD. To better understand the influence of different ranges of TD on disintegration during WD cycles, pH (hydrogen ion concentration) values, electrical conductivity (EC) values, and concentration of cations in leachate released during treatment were measured. The results show that no significant change can be observed under single TD treatment but that TD can increase the disintegration rate by accelerating the water–rock interaction. The effect of TD is more significant for rock with weak resistance to disintegration.

AB  - This research examined the distribution features of red beds and 1,100 Danxia landform sites across
China, while probing the relationship between these spatial patterns and geological elements. This
study is based on geological and tectonic maps of China. ArcGIS software was used to process the
adjacent index, then perform a spatial analysis of Danxia landforms and red beds, and a coupling
analysis of Danxia landforms and red beds with tectonics. Based on a point pattern analysis of Danxia
landforms, the adjacent index is 0.31, and the coefficient of variation verified by Thiessen polygon
reaches 449%. These figures reflect the clustered distribution pattern of the Danxia landforms. Across
the country, Danxia landforms are concentrated into three areas, namely, the Southeast China region,
the Sichuan Basin region and the Qilian-Liupan region. The exposure of red beds covers 9.16 × 105 km2,
which accounts for 9.5% of the total land area of China. With this research background, the geological
elements of tectonics and their effects on the distribution, number, and spatial pattern of Danxia
landforms and red beds were analyzed.

AB  - Natural climate change and human activities are the main driving forces associated with vegetation coverage change. Nanxiong Basin is a key ecosystem-service area at the national level with a dense population and highly representative of red-bed basins, which are considered as fragile ecological units in humid regions. In this study, the authors aimed to determine the trends in vegetation cover change over past two decades and the associated driving forces in this study area. The Normalized Difference Vegetation Index (NDVI) of 2000-2015, derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) remote sensing dataset along with the application of statistical methods and GIS (geographic information system) techniques were used to quantify vegetation cover change. The results show that human-induced factors can explain most variations at sites with significant cover change. That is to say that human activities are the main drivers of vegetation dynamics in this study area, which shows a significant reduction trend in vegetation cover during the industrialization and urbanization processes of the study period and noticeable recovery trend in 2000-2015 under the plantation and enclosed forest policy.
