may have in a year. (2) quantity available. That is, at the existing economic level,
technical conditions can be converted into useful biomass resources. (3) availability?
That is, the amount of biomass energy that can actually be used for energy production = the amount available × the available coefficient. The availability coefficient
is a series of comprehensive expressions of the development potential and industrial
development of industrial oil resources in China, which is a series of non-technical
constraints on biomass energy production. Generally, it includes the share of biomass
resources as energy use and the restriction factors of ecological environment, such as
in order to protect the ecological environment, the harvesting volume of trees should
be moderate, and the sewage charge can be used as external income and so on. Combined with the above theoretical research and methods, the calculation methods of
resource potential of industrial oil energy tree species can be obtained as follows:
Pt = Sot × Qot − Srt × Qrt
Pt The resource potential of oil tree species in t period;
Sot The theoretical upper limit of planting land area of industrial oil tree species
in t period;
Qot The theoretical upper limit of unit yield of industrial oil tree species in t period;
Srt During the t period, the actual land area of industrial oil tree species that was
planted;
Qrt The actual unit production of the first-stage industrial oil tree species at the
time of t.
1.1.3 Relationship Between Cultivation and Ecological
Environment
Fossil fuels were the main source of energy in the past, but in addition to effective
combustibles, fossil fuels often contain a lot of impurities, which may produce toxic
gases and put them into the atmosphere after combustion [23]. The non-combustible
waste is discharged into the ecological environment, which contains toxic substances,
which seriously destroy the ecological environment. And fossil fuel mining process
will also cause environmental pollution; fossil fuels are not inexhaustible; fossil fuels
are heading for the road of energy depletion in recent years.
Interest in alternative energy is rising due to the depletion of oil resources and the
adverse impact of fossil fuel use on the environment. As the limited reserves of fossil
fuels and raw materials in the world, we have aroused active research interest in nonoil, renewable and pollution-free fuels. Biofuel is the only viable source of energy.
In the future, we can form the foundation of sustainable development on social,
economic and environmental issues. The emergence of biodiesel and bioethanol
is a promising energy source in the future. Renewable energy is energy obtained
from renewable resources, which cannot be exhausted for all practical purposes.
