Explanatory Notes on Main Statistical Indicators
Gross Output Value of Farming, Forestry, Animal Husbandry and Fishery refers to the total amount of farming, forestry, animal husbandry, fishery products and the output value of services (refer to the supporting activities for farming, forestry, animal husbandry and fishery ) that behave with the currency. It reflects the total achievement or total scale of agricultural production in form of magnitude of value during a certain period. It is an important synthesis index to observe the agricultural production level and development speed, and study proportionate relationship inside agriculture, proportionate relationship between agriculture and industry, agriculture and national construction, and proportionate relationship of people¡¯s livelihood. And it is also the basic data for calculating the agricultural productivity of labour and agricultural added value.
The Added Value of Farming, Forestry, Animal Husbandry and Fishery refers to the added value of products of farming, forestry, animal husbandry, fishery and relative services, or the added value of providing services. It is calculated by subtracting the intermediate inputs from the gross output value of farming, forestry, animal husbandry and fishery which calculated by the current prices.
Total Power of Farm Machinery refers to the summary of power rating of total power of agricultural machinery. Agricultural machinery refers to the machines and equipment for relative agricultural activities, which including agricultural producing and primary processing for relative products. The total power of farm machinery is calculated by the statutory unit of measurement: KW (note: 1 horsepower=735.5W=0.735KW).
Effective Irrigated Area refers to the cultivated areas whose irrigated project or equipments is in suit, have water source, have been ploughed, and could normally irrigated in usual years. Under normal circumstances, the effective irrigated area should include the total area of paddy fields and irrigated lands which are fitted irrigating projects or equipments and can be irrigated normally.
Consumption of Chemical Fertilizers refers to the chemical fertilizers actually used in agricultural production during the year, including nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and compound fertilizer. Consumption of chemical fertilizers is calculated by 2 methods: practical amount and pure amount. Calculating by pure amount is separately converting the nitrogenous fertilizer, phosphate fertilizer and potash fertilizer into 100% according to their content of nitrogen, phosphorus pent oxide, potassium oxide. Compound fertilizer refers to fertilizer composed by various of nutritional components or elements, such as ammonium phosphate etc. Pure quantity is calculated by the percentage of its content of major component.
Total Sown Area of Farm Crops refers to the total sown area of farm crops which supposed to be harvested as products in the calendar year. Its calculation formula is:
Total Sown Area of Farm Crops = Autumn & Winter Sown Area of Last Year + Spring Sown Area of Current Year + Summer Sown Area of Current Year
= Spring Harvesting Area of Current Year + Summer Harvesting Area of Current Year + Autumn Harvesting Area of Current Year
The Output of Grain refers to the output of the whole society. It includes the grain output from state-owned economy, collective-owned economy and farmer family management, and also includes the output from farms run by industrial & mining enterprises and families and other production units.
The statistics of grains is divided into 3 broad categories. 1. Cereals, including rice, wheat, corn, sorghum, millet and other coarse cereals, the output of cereals is calculated by the threshed and dried grains. 2. Beans, including soybeans, mung beans and red beans etc. Its output is calculated by the dried one without pods. 3. Tubers, including sweet potatoes and potatoes, excluding taros and cassavas, is converted into that of grain at the ratio 4:1, i.e. 4kg of fresh tubers was equivalent to 1 kg of grain up to 1963, since 1964, the ratio for conversion has been 5:1. According to national system, the tubers are calculated by the fresh weight since 2015, and 5 kg of fresh tubers is still calculated as 1 kg of grain. Potatoes and taros in Guangxi are calculated as vegetable before 2009, and since 2009 they are calculated as tubers of grains. The sweet corn was calculated as grain before 2014, and it¡¯s calculated as vegetables instead of grain since 2014.
The Output of Forestry refers to the output of various forestry products which are gained from artificial planted bamboos and trees without felling them down. It includes raw lacquer, palm sheets, Chinese gallnuts, pine resin, bamboo shoots, tea-oil seeds, bancoul nuts, Chinese tallow tree seeds, walnuts, chestnuts and various seeds of trees and branches and leaves trimmed from bamboos and trees (including twigs of the chaste trees, twigs of the willow trees, leaves of palms etc. It excludes leaves of mulberry, leaves of tea trees and fruits; it also excludes the products from wild forests). If it is difficult to discriminate certain kinds of mixed forestry products from artificial ones to wild ones, it should be accounted into the output of forestry or the output of wild plants of other agriculture according to its major resource, and it shouldn¡¯t be calculated in both sides so as to avoiding repetition.
Output of Fruits refers to the output of fruits of trees, vines, perennial herbs and fruited melons produced by agricultural operators in the calendar year. It includes grove fruits and non-grove fruits(melons), but excludes collected wild fruits. The output of fruits is calculated with fresh weight. The dried fruits which have been dehydrated or dried out, such as dried dates, raisins, dried persimmon, tangerine cake, etc. should be converted into the fresh fruit and calculated in unison.
The grove fruits: refers to the fruits produced in professional groves, forestlands and sporadically planted trees (vines) by agricultural operators in the calendar year. It includes apples, pears, oranges, tropical and subtropical fruits and other grove fruit such as peaches, grapes and dates, excludes collected wild fruits. The output of fruits is calculated with fresh weight of fruits actually harvested. The dried fruits which have been dehydrated or dried out, such as dried dates, raisins, dried persimmon, tangerine cake, etc. should be converted into the fresh fruit and calculated in unison.
Total Output of Meat refers to total output of animal meat of various livestock, poultry and rabbits. The output of meat of pigs, cattle, sheep, horses, donkeys, mules and camels is calculated with the weight of carcasses gotten rid of heads, hooves and entrails, and the output of meat of rabbits and poultry is calculated with the weight of carcasses slaughtered and gotten rid of feather and entrails. The output of meat of pigs, cattle, sheep and poultry is gained from the sample monitor investigation of major livestock and poultry, the output of meat of horses, donkeys, mules, camels and rabbits is gained from the full investigation, and the output of meat of other culture of special species could be calculated by the data of household investigation.
Output of Aquatic Products refers to the final effective products of fishery (fishing and cultivating) producing activities, including the final volume of products of all the marine fishes, freshwater fishes, crustaceans(shrimps, crabs), shellfishes, cephalopods, algae and other fishery products, excluding the intermediate products in the fishery producing activities, such as fries, fingerlings, parent fishes, pond fishes, storage pond fishes and products for self-use of fodder. The aquatic products, which have rotten before shoring and cannot be eaten or processing to other products, should not be calculated as the output, too.
