“…Several studies have been conducted on LULCC in high elevation regions, with an emphasis on slopes [8,[17][18][19], mountains [19,20], coastal regions [21][22][23], and elevated terrains of numerous landscape patterns [24,25]. Landscape changes undoubtedly brings both positive and negative changes to an area [21].…”

The Cameron Highlands has experienced multiple land encroachment activities and repeated deforestation, leading to extensive land-use and land-cover change (LULCC) during the past six decades. This study aims to determine the LULCC against topography in Cameron Highlands between 2009 and 2019 by using geospatial techniques to analyze Landsat 7 (ETM+) and 8 (OLI/TIRS), ASTER GDEM and MODIS imaging sensors. The results showed a decline of 35.98 km2 in primary forests over ten years across the Cameron Highlands, while agricultural lands and urban areas flourished by a rise of 51.61 km2 and 11.00 km2 respectively. It can be noted that the elevation most affected is between 1000 and 1500 m, across all classes. Further results showed the expansion of both agriculture and urban development onto slopes above 35°, leading to an instability of soil structure. In a comparison of the base years of 2009 with 2019, mean LST results have shown temperatures rising by 7.5°C, while an average between 3 and 4°C across the region is recorded. The results obtained provide new information for government bodies and land planners to coordinate their actions without further jeopardizing the environment of the Cameron Highlands.

“…In topographically dominated mountain and hill systems, the vertical gradient of land use landscape change is approximately 1,000 times greater than the horizontal gradient and contains rich ecological and geographic information (Lauer, 1993;Korner, 2007). Many types of agricultural land and construction land that are highly disturbed by human activities are distributed in areas with a low altitude and a low urban degree, while woodland and grassland, which are less disturbed by human activities, are more commonly distributed in areas with a high altitude and a large slope (Shen et al, 2011).…”

Understanding the land use and land cover (LULC) pattern of the Qinghai Tibet Plateau in China is crucial to support the structural and functional integrity of the ecological barrier of the plateau. This information has significant implications not only for the ecological environment and regional development of the plateau but also for the broader environmental impact at regional and global levels. It is critical to comprehend the spatial pattern and ascertain the underlying causes of land use and land cover in significant areas of the Qinghai Tibet Plateau. This can enable the formulation and implementation of context-specific policies and measures that can contribute to enhancing the ecological security barrier function of the plateau. This study focused on the core area of the Qinghai Tibet Plateau - the Qiangtang Plateau. Based on surface cover data from 2020 and ASTER GDEMV3 data, distribution indices and geographic detectors were used to explore the quantitative impact of land use/cover spatial patterns and terrain factors on land use/cover spatial distribution. The results showed the following: 1) The land use/cover space of the Qiangtang Plateau was dominated by grassland and bare land. Specifically, grassland had the greatest area, accounting for approximately 63.94% of the plateau area and covering an area of 449,983 km2. Grassland was widely distributed in most areas of the plateau. Bare land was the second-largest land cover type, with an area of 186,302 km2, accounting for 26.47% of the plateau area. Bare land was primarily located in the western and northern parts of the plateau. 2) The spatial differentiation of land use/cover in the Qiangtang Plateau was significant. Grasslands were primarily distributed in low mountainous areas characterized by high relief, gentle slopes, and low roughness. In contrast, bare land was mainly distributed in low mountainous areas with high relief, steep slopes, and low roughness. 3) The main drivers of the spatial distribution of land use/cover on the Qiangtang Plateau were elevation, roughness, and relief. Moreover, the interactions between these three terrain factors and other environmental variables significantly influenced the land use/cover pattern in the study area.

“…For example, Zhu Zhanqiang [4] et al explored the impacts of afforestation on the landscape pattern in Ningnan's loess hilly region by taking the small watershed of Zhongzhuang Village as an example; Fang Xuan [5] et al studied the relationship between small-watershed vegetation pattern and terrain in the Loess Plateau by taking Shanghuang Experimental Area of Guyuan as an example; Dong Youfu [6] et al used terrain niche index and landscape-type transition matrix to conduct quantitative analysis and discussion on the terrain gradient features of this region's landscape pattern and its varying patterns by taking Guyuan County at the upper reach of Jinghe River; Shen Huaifei [7] et al used DEM to analyze the terrain gradients of land-use spatial pattern in the Yellow River Basin of western Henan. These studies mostly targeted the land use of provinces, districts/counties and mountainous areas, of which the landscape types can be basically divided into the following categories: category of agriculture, forestry and animal husbandry by land use; category of arable lands, slopes, ravines, sand and dilapidated granite by managed objects; and category of crop management, soil management and water management from management perspectives [7] ; over the past decade, the loess hilly region in southern Ningxia suffering from severe soil erosion has been well managed, especially eco-based Pengyang County, of which the land use basically shows the landscape of intersected ravines and comprehensive management for small watershed. However, studies on landscape type division where the land-use classification criteria are taken as the ecological restoration measures in line with the actual landscape of the region and in combination with the topographic analysis of the loess hilly region are not commonly seen.…”

Small watershed is the basic unit of soil and water conservation management in the Loess Hilly Region, and the spatial distribution of different landscapes for land use in small watershed has restricted a variety of ecological processes and ecological benefits of landscapes. This paper combines a geographic information system (GIS) and statistical analysis to reveal the relationship between the spatial distribution of landscape types and topographic factors such as elevation, slope and aspect so as to explore the influences of topographic factors on the spatial distribution pattern of different ecological restoration measures. Gaojianbao Watershed, a typical loess hilly region , is the study area. A land-use map (scale1:50000,2013) of the study area and the topographic map (1:100,000) were used as the base data. The study area is divided into 8 landscape types by the classification of ecological restoration measures. The results showed that: topographic factor is an important factor affecting the watershed ecological restoration, and the spatial distribution of ecological restoration landscapes in Gaojianpu Watershed was significantly associated with topographic factors, featuring obvious vertical distribution. With the rise of elevation, the distribution of landscape types showed the order of ditch protection forest to fruit forest to afforestation (grassland restoration) to barren hills under natural enclosing to level terrace to fish-scale pit to barren hill under afforestation; the spatial distribution of each landscape component was greatly influenced by slope, and the distribution ratio first increased gradually and then decreased; when the aspect shifts from shady to sunny, the distribution ratio of landscapes like afforestation (grassland restoration), level terrace and barren hills under afforestation decreased while the distribution ratio of barren hills under natural enclosing and fruit forests increased, and the landscapes of fish-scale pits and ditch protection forests were basically not affected by aspect.
