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. The first agriculture census of China in 1996 revealed some discrepancy between the production of animal products
from the annual reports and that from the census. Efforts were made by the Rural Socio-economic Survey Organization of NBS
to adjust the output value of animal husbandry to make the figures from the annual reports consistent with the census data.
Grain Output refers to the grain production 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.
Cotton Output refers to the cotton production in the whole country including cotton sown in spring and in autumn. Output is
measured as the weight of ginned cotton.
Output of Oil-bearing Crops refers to the total production 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.
Regularly Cultivated Land refers to farmland among the total land resources which is exclusively used for farming and is
under regular cultivation with harvest in normal years. Included are currently cultivated land, land that has been abandoned or
put in idle for less than 3 years and could be re-used for cultivation at any time, and new-claimed land that has been put into
cultivation for more than 3 years. Excluded under this category are steep slope land over 25 degrees under temporary
cultivation, land (large or small plots) that is claimed along river bends, lake sides or banks of reservoirs, as well as land that
has been designated under the "Green for Grain" programmes of the state and provincial governments but is still temporarily
under cultivation.
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. Under normal conditions,
irrigated area is the sum of watered fields and irrigated fields where irrigation systems or equipment have been installed for
regular irrigation purpose.
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.
