By purposes of use, forests are divided into protection forests, special-use forests
and production forests.
Protection forests: forests are mainly used to protect water resources, protect
land, prevent erosion, combat desertification, limit disasters, regulate climate and
protect the environment.
Special-use forests: forests are mainly used for nature conservation, the
standard sample of the national ecosystem, and forest genetic resources; scientific
research; protection of historical and cultural relics, tourist attraction; serve for rest
and tourism, combined with environmental protection.
Production forests: forests are mainly used for production and trading of
timber, and non-timber forest products, combined with purposes of protection and
environmental protection.
The existing forest area refers to the total forest area at a given time.
Output of timber and non-timber forest products includes output of timber,
firewood, bamboo, neohouzeaua, bambusa nutans, dendrocalamus barbatus, etc., and
other products such as shellac, resins, oleaginous fruits, nuts, etc., harvested and collected
from natural forests, planted forests and scattered forests in a certain period of time.
FISHERY
Water surface area for aquaculture is the area used for aquaculture, including
the area of embankment; for aquaculture breeding and hatchery area includes
necessary supplement areas such as filtering ponds and letting out ponds. This
indicator does not cover areas of land with special-use water surface for other
purposes, but are used for aquaculture such as irrigation and hydropower reservoirs.
Aquatic production refers to volume of an aquatic product or a group of aquatic
species obtained during a given period, including aquatic capture production and
aquaculture production:
Aquatic capture production includes production of catches from the sea, and
production of naturally captured from rivers, streams, lakes, lagoons, or rice fields, etc.
Aquaculture production includes all aquaculture production resulting from
aquaculture.
Quantity and capacity of motorized marine vessels and boats is the number
of actual vessels, boats engaged in marine capture fisheries during the year;
including newly-built motorized boats and vessels for purposes of long-term marine
capture fisheries.
Capacity of vessels and boats is the total available capacity of the main engines
of vessels and boats at a given time. Unit of capacity is horsepower (CV). Motorized
vessels and boats for marine capture fisheries are divided into different groups: less
than 20 CV; from 20 to under 50CV; from 50 to under 90CV; from 90 to under 250
CV; from 250 to under 400 CV; from 400 CV and over.
