农林牧渔业总产值 是以货币表现的农、林、牧、渔业全部产品的总量，它反映一定时期内农业生产总规模和总成果。
    农、林、牧、渔业的统计范围包括国有经济的各种专业农（农、林、牧、渔）场以及国家各级机关团体学校、部队；集体所有制的乡、镇、村各级办农场；工矿企业经营的农、林、牧、渔业，农村各种经济组织和农户经营的农林牧渔业和农民家庭兼营的商品性工业等。
    （1）农业包括种植业和其他农业。
    种植业包括谷物、豆类、薯类、棉、油料、糖料、麻类、烟叶、蔬菜、药材、瓜类和、其他农作物的种植，以及茶园、桑园、果园的生产经营。其他农业包括采集野生植物的果实、纤维、树胶、树脂、油料以及柴草、野生药材、菌类等及农民家庭兼营的商品性工业。

    （4）渔业包括水生动物和海藻类植物的养殖和捕捞。
    农业总产值的计算方法通常是按农林牧渔业产品及其副产品的产量分别乘以各自单位产品价格求得，少数生产周期较长，当年没有产品或产品产量不易统计的，则采用间接方法匡算其产值，然后将四业产品产值相加即为农业总产值。
    1957年以前的农业总产值中包括了厩肥和农民自给性手工业（如农民自制衣服、鞋、袜，自己从事粮食初步加工等）。1958年及以后的农业总产值，林业中增加了村及村以下竹木采伐产值；牧业中取消费厩肥产值；副业中取消了农民自给性手工业产值，增加了村及村以下办的工业产值；渔业中增加了海洋捕捞水产品产值。1980年及以后的农业总产值，在副业中增加了农民家庭兼营工业商品部分的产值。从1984年起村及村以下办工业产值划归工业。从1993年起，取消副业。将野生动物的捕猎划人牧业，野生植物采集和农民家庭兼营商品性工业划归农业。

Gross Output Value of Farming Forestry, Animal Husbandry and Fishery refers to the total volume of products of farming, forestry, animal husbandry and fishery in value terms, which reflects the total scale and total result of agricultural production during a given period of time.
The statistical coverage of farming, forestry, animal husbandry and fishery are as follows: 
In terms of ownership, China's agriculture includes specialized state farms (farming, forestry, animal husbandry, fishery), farms managed by various government agencies, organizations, schools, research institutions, and army; farms managed by rural collective organizations at levels of township, town, and village; farming, forestry, animal husbandry, fishery run by mining and industrial enterprises; farming, forestry, animal husbandry and fishery and some commodity industries run by various rural collective organizations and individual farmers.
(1) Farming includes cultivation of farm crops and other agricultural activitiesa￥
Cultivation includes the cultivation of grain crops, beans, tubers, cotton, oil-bearing crops, sugar crops, fiber crops, tobacco, vegetables, medicinal herbs, melons and gourds, and cultivation and management of tea plantations, mulberry fields and orchards.
Other agricultural activities includes gathering fruits, fiber, gum and resin of wild plants, oil-bearing plants, grass, wild medicinal herbs, fungus plants, and commodity industries of the rural households.
(2) Forestry refers to planting trees of various kinds (excluding tea plantations, mulberry fields and orchards), gathering of forest products, and cutting and felling of bamboo and trees by villages and other cooperative organizations under villages.
(3) Animal husbandry refers to raising and grazing of all animals except fishery and aquaculture, and hunting and raising of wild animals.
(4) Fishery refers to cultivation and catching of fish and other aquatic animals and cultivation and collection of seaweed and other aquatic plants.
Gross output value of agriculture is obtained by first multiplying the output of each product or by-products 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, China's 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 cooperative organizations 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 he 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 ration 4:1, i.e. four kilograms of fresh tubers was equivalent to one 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 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.
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, forestland, reed land, natural and man-made grassland and other land are not included in cultivated land.

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 for Farming 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 content in phosphate fertilizer, 100% potassium oxide content 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 sloughing, irrigation and drainage, harvesting, transport, plant protection, stockbreeding, 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.
