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

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.
