Abstract: The effect of vegetation
on soil and water conservation
increases with the increase of planting density. At the same time, the
degree of soil drought increases with the increase of planting density,
and leads to the decline of vegetation or waste
resources and then affects the
benefit of vegetation on soil and water conservation. However, there is
a few research of high-quality
sustainable management of easier degraded soil and water conservation
vegetation ecosystems. In this
paper, the high-quality
sustainable management of soil and water conservation vegetation was
reviewed. The results showed that the degree of cover of soil and water
conservation vegetation increases with increasing density under other
things being equal; the canopy interception increases with stand density
but there is a peak value of canopy interception. The surface runoff
decreases with increasing density with a logarithm relationship; the
sediment charge in the runoff increases with reducing density with a
logistic relation. There is a limit of soil and water conservation
vegetation, which is the cover degree of soil and water conservation
vegetation when the existing plant
density of indicator species in a plant community is equal to
vegetation carrying capacity. When
plant density of indicator species in a plant community is more than
vegetation carrying capacity, the cover degree of soil and water
conservation vegetation is more than the vegetation restoration limit of
soil and water conservation vegetation, the plant resources relationship
should be regulated based on vegetation carrying capacity to realize
high-quality sustainable
management of soil and water
conservation vegetation.
