How does slope affect the ecosystem?

Slope aspect is known to affect the diversity and density of plant communities. Sunny slopes retain less moisture because of stronger solar radiation and higher evaporation. Therefore, plants on sunny slopes, such as grasses, are more likely to be drought- and radiation-resistant.

What is slope in ecosystem?

Slope angle, aspect, and elevation are considered as the primary factors creating spatial variation, causing differences in vegetation growth and distribution, ecosystem functioning, and processes. … In the low-latitudinal region, the slope aspect shows no consistent differences between the opposite aspects.

What is the effect of slope on climate?

The effect of slope aspect and gradient on soil temperature varies with time. In the non-growing season, the south-facing slope and swale receive more solar radiation and are warmer than the north-facing slope and swale.

How does steep slopes affect plants?

Evaporation is more rapid on south-facing slopes compared to shady north-facing hills; the heat concentrates on the soil to make it warmer throughout the day. Steeper slopes also magnify the heat on the soil; plants that are drought-tolerant and crave warm temperatures are perfect for this particular slope angle.

Why is slope aspect important?

Slope aspect plays a critical role in influencing vegetation pattern in semiarid area. … We found significant vegetation differences between slope aspects in species composition, vegetative structure, and biodiversity pattern, which were in accordance with the observed significant difference in soil nutrient.

How does slope aspect affect evaporation?

Depending on the season, evaporative loss was affected more or less significantly by slope aspect. On all quadrants, greatest evaporative loss occurred at the top of slope and least occurred on the lee side of the hill which was most shaded.

How does slope and aspect affect temperature?

The aspect of a slope can make very significant influences on its local climate (microclimate). … Similarly, in the northern hemisphere a south-facing slope (more open to sunlight and warm winds) will therefore generally be warmer and drier due to higher levels of evapotranspiration than a north-facing slope.

How does slope affect soil temperature?

The temperature of the soil decreases with increase of altitude. The temperature of the soil is usually higher on south-facing slopes than on north-facing slopes. … The difference between maxima on north and south slopes increases with increase of altitude.

How do altitude and slope affect the climate?

At higher altitudes, the air is less dense and air molecules are more spread out and less likely to collide. A location in the mountains has lower average temperatures than one at the base of the mountains. … rainshadow effect, which brings warm, dry climate to the leeward side of a mountain range (Figure below).

Which slope is better for plant growth?

South-facing slopes (SFS) may receive six times higher solar radiation than north-facing slopes (NFS). Although located only a few hundred meters apart, the microclimatic conditions on the slopes vary dramatically, affecting the biology of organisms at all levels.

How does slope contribute to soil properties and characteristics?

The aspect and slope can control the movement of water and material in a hillslope and contribute to the spatial differences of soil properties. … The results of redundancy analysis (RDA) also revealed clear separation of soil properties among slope positions.

What is the effect of slope on soil?

The steep slope will increase the number and speed of runoff so that erosion will be accelerated due to more transported and dissolved materials [3]. Steeper slope will enhance the flow resulting a bigger power and amount of water to transport the soil.

How does slope affect a watershed?

Runoff will flow faster on a steeper slope. This results in higher peaks at downstream locations. The effect of land slope on the volume is usually minor. The shape of the watershed has an effect on the rate of runoff.
