Conclusions
Along with time going by, plant growth, the plant-resources relation
should be considered. In a growing season, as plant grows, plant growth
goes into the fast growth stage, the leaves were totally expansion and
the
plant-resources relation may goes
into the critical period of plant- resources relationship regulation If
the available resources are lower than resource use limit by plants (Guo
2021a and 2021b). Plant was very sensitive to resources storage in this
period. If the duration of resource scarcity is more than the critical
period of plant- resources relationship regulation or plant density is
more than soil water carrying capacity, showing that resource shortage
is serious and serious influence
soil and water conservation vegetation restoration and the
plant-resources relation must be regulated by cutting some trees and
reduce plant density in this stage based on vegetation carry capacity to
realize high-quality and sustainable development of soil and water
conservation vegetation.
In view of the important of the potential of
soil and water conservation
vegetation restoration in the process of high-quality development and
soil and water conservation vegetation restoration is close related with
vegetation carrying capacity and
vegetation carrying capacity change with forest age because
precipitation change with years (Guo 2014) and vegetation types and
location, we should strengthen the studies of the plant-resources
relationship and decide vegetation carrying capacity and the limit of
forest vegetation restoration at different years in order to promote the
high-quality sustainable management of
soil and water conservation
vegetation and get maximal soil and water conservation beneficial to
match the People’s yearning for a better life and the need for soil and
water conservation(Guo 2020,2021a and b).
