Land productive potential, also known as land productivity, refers to the maximum productive capacity of land under the current level of farming technology and corresponding measures.
Discipline: Land science and management
Headings: Land production potential
english: land potential productivity，land productivepotential
annotations: The possible biological yield or harvest yield per unit area of land determined by natural factors such as light, temperature, water, soil and nutrients. Within a region land resource The potential to produce energy and protein quality (or food, meat and eggs) that can be used for people's physiological needs, including all arable land, gardens, pastures, waters, etc. that can be used for agricultural production. The relatively complete methodological basis and specific systematic working procedures for the study of land productive potential were in the 1970s FAO Popularized Agroecological zone law (Agro ecological zone, AFZ). It is a regional division of the ecological conditions of agricultural production climate, terrain, soil, etc., using a hierarchical similar geographical method, such as calculating the productive potential of their land resources respectively. Its advantages are: ① it correctly applies the relationship between various components of land resources and crop yield formation, such as light, temperature, water in the atmosphere and various fertility factors of soil. ② It uses the logical relationship between various land factors and crop yield forming factors in each agricultural ecological region. ③ Its working mode has been continuously improved and expanded, and it was applied to the computer programming work at the end of the 1980s, with updated development. Specific land production potential includes Climatic productive potential 、 Soil productive potential 、 Social and economic input benefits and Population carrying capacity Calculation and other four major contents. [1] definition: Land productive potential (or land productivity) refers to the maximum productive capacity of land under the current level of farming technology and corresponding measures. Its exact meaning includes theoretical potential and practical potential. In agriculture, land productivity refers to the ability of land in a region to produce energy and protein that people may use. For cultivated land and grain crops For example, land productivity refers to the energy or quantity of grain production per unit area of cultivated land.
