“…elevation>800 m) and plains (i.e. elevation<30 m and slope<5 °) at large scales, which were consistent with related studies conducted through geographic weighted regression approach in mountain-hill region (Qiu et al 2012;Qiu et al 2013b). Intensive influence from anthropogenic activities mainly occurred in areas with relatively low elevation and gentle, concave slopes, which was also indicated in other research conducted in arid regions (Liu et al 2009).…”

Abstract:The scale-location specific control on vegetation distribution was investigated through continuous wavelet transforms approaches in subtropical mountain-hill region, Fujian, China. The Normalized Difference Vegetation Index (NDVI) was calculated as an indicator of vegetation greenness using Chinese Environmental Disaster Reduction Satellite images along latitudinal and longitudinal transects. Four scales of variations were identified from the local wavelet spectrum of NDVI, with much stronger wavelet variances observed at larger scales. The characteristic scale of vegetation distribution within mountainous and hilly regions in Southeast China was around 20 km. Significantly strong wavelet coherency was generally examined in regions with very diverse topography, typically characterized as small mountains and hills fractured by rivers and residents. The continuous wavelet based approaches provided valuable insight on the hierarchical structure and its corresponding characteristic scales of ecosystems, which might be applied in defining proper levels in multilevel models and optimal bandwidths in Geographically Weighted Regression.

“…Atmospheric counter radiation was much more important for vegetation than precipitation, soil, and altitude. Because most of the study area was located in high mountains, energy should be the most important variable for maintaining vegetation, as reported by other studies (Qiu, Zeng, Chen, Zhang, & Zhong, 2013;Sohoulande Djebou et al, 2015).…”

Vegetation patterns and spatial organization are influenced by the changing environmental conditions and human activities. However, the effect of environment on vegetation at different vegetation classification levels has been unclear. We conducted an analysis to explore the relationship between environment and vegetation in the land use/land cover (LULC), vegetation group, vegetation type, and formation and subformation levels using redundancy analysis with seven landscape metrics and 33 environmental factors in the upper reaches of the Heihe River basin in an arid area of China to clarify this uncertainty. Atmospheric counter radiation was the most important factor at the four levels. The effect of soil was the second determinant factor at three levels

“…The typical topographies in the study area are flat ground, gentle slope and large sand dunes. According to vegetation-topography interaction (Qiu et al, 2013) and methods for vegetation evaluation (Qian et al, 2004;Ma et al, 2011), typical sites with representative vegetation of 4 terrains (flat ground, gently sloping area, middle part of the slope of a dune and top of a dune) were selected. The location of the four sites were 44°95′N, 88°70′E; 44°93′N, 88°54′E; 45°00′N, 88°55′E; 44°93′N, 88°63′E, respectively.…”

The distribution of plant species and relationships between species and soil factors in the east central part of Gurbantunggut Desert was studied to provide more insight into the flora and determine differences in vegetation across various parts of the desert. Two-way Cluster Analysis showed that the vegetation in the area could be divided into three groups, the first group was dominated by the shrub species, Ephedra przewalskii and the grass species, Carex physodes mainly in areas of flat grounds and gentle slopes; the second group was dominated by C. physodes, Artemisia songorica and A. xerophytica mainly on the slope of sand dunes and the third group was dominated by the shrub species, Haloxylon persicum mainly on the top of sand dunes. There was no difference in plant density between Groups 1 and 2 but there was a significant decrease in Group 3. Soil water under vegetation Group 3 was much lower than that in the other two groups at all soil depths. The EC, organic matter, total P and soluble Na, Ca and Mg varied very similarly with soil water. Canonical correspondence analysis (CCA) satisfactorily assessed the species-soil relations in the area. The distribution of plant species was strongly correlated with the soil factors of water content, organic matter, EC and nutrients. The variations in species occurrence explained by the three CCA axes were about 70%, indicating that some explanatory site variables may exist outside our studied parameters. Soil texture is suggested to be included in future studies to improve the explanation of CCA.
