Grain production capacity checking method for tilled land

Abstract

The invention belongs to tilled land resource evaluation and utilization field and relates to a multi-tier tilled land production capacity checking method based on grade, establishes a quantitative checking model between tilled land index and standard grain production capacity based on tilled land quality evaluation, separately checks actual production capacity, achievable production capacity, theoretical production capacity of tilled land. The actual production capacity of tilled land is checked by actually investigating specimen for establishing model; achievable production capacity is checked by establishing model of utilization index of tilled land and achievable sampling point; theoretical production capacity is checked according to model of natural quality index of tilled land and theoretical sampling point. Different-tier production capacity is compared to compute utilization rate and increase production potential of tilled land, and to provide scientific basis for quality management, protection, utilization efficiency evaluation and moving of tilled land, which has significance to promoting sustainable development of agriculture and assuring grain safety.

Description

Technical field: [0001] The invention belongs to the field of evaluation and utilization of cultivated land resources, and is an accounting method for calculating the actual production capacity, realizable production capacity and theoretical production capacity of cultivated land grain production based on grades. Background technique: [0002] From an economic point of view, both Maslow's "Need Hierarchy Theory" and Marx's economic theory point out that a society can only carry out other activities after meeting people's survival needs. The so-called survival needs are, of course, the first and foremost "eating problem". In my country and most countries in the world, food is people's staple food, and people's eating habits are not easy to change. In our foreseeable future, no matter how society develops and how technology advances, the problem of food will still be the most basic problem of human life. China is a country with a population of 1.3 billion, coupled with the e...

Problems solved by technology

[0022] To sum up, in recent years, the research on cultivated land production capacity in my country has achieved fruitful results, but there are still several problems in the method and technology of cultivated land production capacity accounting: ① The understanding of the connotation of cultivated land comprehensive production capacity exists or is too much General or not comprehensive; ②The index weights are determined by experience, and a complete method system for the calculation of cultivated land production capacity has not been formed, and there are few studies on the spatial variation pattern and spatial differentiation of production capacity in different regions; ③Cultivated land production at different levels The capacity accounting method is not yet clear; ④ It is impossible to predict the long-term arable land production capacity, and the short-term arable land production capacity prediction method is too simple and rough, and the prediction results are affected by many factors, with large errors

In short, at present there is no complete set of methods and technical systems with scientific and accurate calculation and prediction results that can reflect the comprehensive production capacity and production potential of cultivated land at multiple levels
