JINAN STATISTICAL YEARBOOK Explanatory Notes on Main Statistical IndicatorsGross Output Value of Farming, Forestry, Animal Husbandry
and Fishery refers to the total value of products (expressed in monetary
terms) of farming, forestry, animal husbandry and fishery, and total value
of services in support of farming, forestry, animal husbandry and fishery
activities. It reflects the total scale and results of agricultural production
during a given period.
Gross output value of farming is calculated by product method, and
is obtained by 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
values of all products of farming, forestry, animal husbandry and fishery
and professional and support activities in farming, forestry, animal
husbandry and fishery is then equal to the gross output value of
agriculture.
Grain Output refers to the total output of grains produced within a
calendar year. It includes summer crops, early rice and autumn crops by
harvest seasons; and covers cereals, beans and tubers by type of crops.
Output of cereals cover husked grain only. Output of beans refers to dry
beans without pods. The output of tubers (sweet potatoes and potatoes,
not including taros and cassava) are converted with the ratio of 4:1, i.e. 4
kilograms of fresh tubers were equivalent to 1 kilogram of grain before
1964. Since 1964 the ratio has been changed to 5:1. Tubers consumed 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. Data on
grain production before 1989 were obtained through the comprehensive
statistical reporting system. Since 1989, data from sample surveys are used.
Cotton Output refers to cotton production in the whole country
including cotton planted in spring and in summer. Output is measured as
the weight of ginned cotton. Ceiba is not included.
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 final output actually yielded
from fishing production (fishery and breeding), including all output of
marine and freshwater fish, crustaceans (shrimps, crabs), shellfish,
cephalopod, seaweed and other fishery products. Data on output of
aquatic products are reported by fishery agencies level by level. Before
1995, among the shellfish, oyster was counted as fresh meat; and 5
kilograms of ark shell, clams and frogs were equivalent to 1 kilogramoffresh aquatic products; they have all been counted as freshaquaticproductssince 1996.
Output of Pork, Beef, Mutton and Poultry refers to the meat ofslaughtered hogs, cattle, sheep and goats with head, feet, and offal takenaway. Before 1996, data were obtained through bottom-upcomprehensive reporting system. The first agricultural census of Chinain1996 revealed some discrepancy between the production of animal
products from the annual reports and that from the census. Efforts weremade to adjust the output value of animal husbandry to make the figuresfrom the annual reports consistent with the census data. Since 1999, theNBS conducted sample surveys in selected regions for the major animal
husbandry products, such as hogs, cattle, sheep and goats and fowls, andthe data from sample surveys are used as finalized national data.
Production of other regions which are not covered by the sample surveyis still reported by statistical agencies level by level. Amonitoringandsurvey program was set up in 2008 on main livestock, and data onthemain livestock such as hog, cattle, sheep and poultry fromthe samplesurvey became the official data.
Sown Area of Crops refers to area of all land (cultivatedornon-cultivated area) sown or transplanted with crops that are harvestedwithin the calendar year. All crops harvested within the year are countedas sown area, regardless of being sown in this year or the previous year.
Crops sown this year but will be harvested in the coming year areexcluded.
Consumption of Chemical Fertilizers in Agriculture refers tothequantity of chemical fertilizers applied in agriculture in the year,
including nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, andcompound fertilizer. The consumption of chemical fertilizersiscalculated in terms of volume of effective components by meansofconverting the gross weight of the respective fertilizers intoweight
containing effective component (e.g. nitrogen content in nitrogenousfertilizer, phosphorous pentoxide contents in phosphate fertilizer, andpotassium oxide contents in potash fertilizer). Compound fertilizer isconverted in regard to its major components. The formula is:
Volume of effective component= physical quantity×effectivecomponent of certain chemical fertilizer (%)
Total Power of Agricultural Machinery refers to the total ratedcapacity of all agricultural machinery. Agricultural machinery referstothe machines and equipment which are used for activities of farming,
animal husbandry, fishery, primary processing of agricultural products,
agricultural transport and infrastructure construction of farmland.
