“…Soil C and TN are controlled by various natural factors such as climate change (He et al, 2014;Rustad and Fernandez, 1998), topographical factors (Fernández-Romero et al, 2014;Griffiths et al, 2009;Kunkel et al, 2011;Parras-Alcántara et al, 2015b), vegetation conditions (Fu et al, 2010;Kunkel et al, 2011) and soil properties (Côté et al, 2000;Su et al, 2007). Anthropogenic activities have been shown to have profound impacts on soil C and TN status in recent decades .…”

“…Globally, it is estimated that about 40% of the global population lives in watersheds of rivers originating in the planet's different mountainous regions (Beniston 2003). Mountains modify local climates, control river flow regimes, and determine soil types Nogués-Bravo et al 2007;Griffiths et al 2009). Mountains fulfill important ecological and economic functions for the surrounding lowlands, including the sustenance of ecological minimum flows, water resource for agriculture, food production and hydropower generation ).…”

Abstract:In arid regions, mountains fulfill important ecological and economic functions for the surrounding lowlands. In the scenario of global warming, mountain ecosystems change rapidly, especially in the arid region of northwestern China. This paper provides an assessment of the changes in temperature and precipitation in the historical records of climate on the northern slopes of the eastern Tianshan Mountains. A Mann-Kendall nonparametric trend and Sen's tests are employed to analyze the interannual changes and innerannual variability in temperature and precipitation in the regions of low to high altitude. The present study finds that the largest increases in annual temperature are observed at stations in the low altitude regions. The significant increasing trends in temperature tend to occur mainly in late winter and early spring at stations from middle to high altitude, but in summer and autumn at stations of low altitudes. The increasing trends in annual precipitation are found from the middle to high altitude areas, but decreasing trends are found in the low altitude areas. The significant increasing trends in precipitation occur mostly in winter and earlier spring at stations from the middle to high altitudes, while the increasing and decreasing trend coexists at stations of low altitude with most of the significant trend changes occurring in March, June and August.

“…Similar finding was also reported by Singh and Kashyap (2006) in Bindhyan region, Utter Pradesh, India and Kidanemariam et al (2012) in Tsegeden highlands, northern Ethiopia. Griffiths et al (2009) also found an opposite relationship between elevation and bulk density in Oregon Cascade Mountains. The relatively lower value of bulk density in HSF might be due to presence of higher organic matter accumulation in the soil than the TSF.…”

Physico-chemical properties of forest soil depends on a variety of natural factors, the most important are variation in altitude, vegetation cover and microbial activities. The present study was conducted to understand the effect of variation in altitude in the soil characteristics in Tarai Sal forest (TSF) and Hill Sal forest (HSF), of eastern Nepal. Soil samples were collected from thirty plots randomly in each forest from 0-15cm and 15-30cm depths in May 2012. Both forests had sandy loam type of soil texture. However, the percentage composition of soil particles varies within the forest sites. Soil moisture was higher in TSF. It was maximum in the rainy season in both forests. Water holding capacity was slightly higher in TSF. Bulk density was higher in TSF and it increased with soil depth in both forests. The pH value was slightly higher in HSF than TSF however, the value increased in lower soil depth in both forest stands. In the upper soil layer (0-15cm) soil organic carbon (SOC) was higher in HSF (2.09%) than TSF (1.6%). Similarly, total nitrogen (TN) was also higher in HSF (0.173%) than in TSF (0.129%) while total phosphorus (TP) was more or less same in both forest stands. The potassium (K) a soil extractable nutrient also showed higher value in HSF (312.13 µg g . The values of SOC, TN, TP and K decreased in lower depth (15-30cm) in both forest stands. In conclusion, variation in altitude causes difference in the microclimatic condition which resulted into the alternation in soil characteristics.
