L-Explanatory Notes on Main Statistical
Indicators |
Gross
Output Value of Farming, Forestry, Animal Husbandry and Fishery refers to the total
value of products of farming, forestry, animal husbandry and fishery, which
reflects the total scale and result of agricultural production during a given
period.Gross output value of agriculture is obtained by first multiplying the
output of each product or by product by its price, resulting in the output
value of each single item. For a small number of products, annual output of
which is not available or difficult to get due to the long production growing
process involved,the output value is estimated through an indirect
approach.The sum of output value of all products of farming, forestry, animal
husbandry, and fishery is then equal to the gross output value of
agriculture. Prior to 1957, Chinas gross agricultural output value included barnyard
manure and handicraft products for self consumption (clothes,shoes,stockings,and initial grain processing undertaken
by peasants). Since 1958, cutting and felling of bamboo and trees by villages
and other cooperative organizations under villages have been included in
forestry; value of barnyard manure has been excluded from animal husbandry;
self consumed handicrafts has been excluded from sideline occupations,while
the output value of industries run by villages and cooperative organizations
under village had been included
in sideline occupations and the output value of fish catches by motor fishing
boats has been added to fishery. Since 1980, the value of handicraft products
made for sale by individuals in households had been added to sideline occupations.
Since 1984, industries run by villages and under villages have been included
in the sector of industry.Since 1993, the subdivision of sideline occupations
has been canceled, and the hunting of wild animals has been classified into
animal husbandry, and the gathering of wild plants and commodity industry run
by rural household have been included in farming. |
Grain
Yield refers to the yield
in the whole country including grains produced by state farms, collective
units, industrial enterprises and mines.Grain includes rice, wheat, corn,
sorghum, millet and other miscellaneous grains as well as tubers and beans.
Output of beans refers to dry beans without pods. The output of tubers (sweet
potatoes and potatoes,not including taros and
cassava) was converted into that of grain at the ratio 4:1, i.e. 4 kilograms
of fresh tubers was equivalent to 1 kilogram of grain up to 1963.Since 1964
the ratio for conversion has been 5:1. Tubers supplied as vegetables (such as
potatoes) in cities and suburbs are calculated as fresh vegetables and their
output is not included in the output of grain. Output of all other grains
refers to husked grain. |
Yield
of Oil-bearing Crops refers
to the total yield of oil bearing crops of various kinds,including peanuts,
(dry, in shell) rapeseeds, sesame, sunflower seeds, flax seeds, and other oil
bearing crops.Soybeans,oil-bearing woody plants,and wild oil-bearing crops
are not included. |
Output
of Aquatic Products refers to catches of
both artificially cultured and naturally grown aquatic products, including
fish,shrimps,crabs and shellfish in sea and inland water as well as seaweed.
Freshwater plants are not included. |
Output
of Pork,Beef,and Mutton refers to the meat of slaughtered
hogs,cattle,sheep and goats with head,feet, and offal taken away. |
Number
of Livestock or Poultry in Stock at Beginning (or End) refers to the
total number of large animals,pigs,sheep,fowls,etc.raised by rural
cooperative organizations,state farms,rural individuals,government
agencies,schools,industrial and mining enterprises,army,and urban residents
at the beginning (or end) of the reference period. |
Cultivated
Area (Area under cultivation)
refers to farmland which is plowed constantly for growing crops,including cultivated land, newly cultivated land in the
current year,farmland left without cultivation for less than three years and
fallow land in the current year,rotation land, rotation land of grass and
crops, farmland with some fruit trees, mulberry trees and other trees and
cultivated seashore land, lake land, and etc. The land of mulberry fields,
tea plantations,orchards, nurseries of young plants,
forest land, reed land, natural and man-made grassland and other land are not
included in cultivated land. |
Sown
Area of Crops refers to area of
land sown or transplanted with crops regardless of being in cultivated area
or non cultivated area. Area of land re-sown due to natural disasters is also
included. |
Irrigated
Area refers to areas that
are effectively irrigated, i.e. level land which has water source and
complete sets of irrigation facilities to lift and move adequate water for
irrigation purpose under normal conditions. |
Consumption
of Chemical Fertilizers in Agriculture refers to the quantity of
chemical fertilizers applied in agriculture in the year, including
nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, and compound
fertilizer. The consumption of chemical fertilizers is required in
calculation to convert the gross weight into weight containing 100% effective
component (e.g. 100% nitrogen content in nitrogenous fertilizer, 100%
phosphorous pentoxide contents in phosphate fertilizer, 100% potassium oxide
contents in potash fertilizer). Compound fertilizer is converted with its
major component. |
Total
Power of Farm Machinery refers to total
mechanical power of machinery used in farming, forestry, animal husbandry,
and fishery, including ploughing, irrigation and drainage, harvesting,
transport, plant protection, stock breeding, forestry and fishery. The power
of internal combustion engines is required to convert horsepower into watts
and the power of electric motors is required to be converted into
watts.Machinery employed for non agricultural purposes, such as the machines
used in township run and village-run industry,construction,non agricultural
transport,scientific experiments and teaching, is excluded. |
Labour
Force Engaged in Farming,Forestry,Animal Husbandry
and Fishery refers to the total
laborers who are directly engaged in production of farming,forestry,animal
husbandry and fishery. |
