Construction Of Jiangsu Province Grain Yield Prediction Model Based On SPSS

The development of the national economy depends on the development of agriculture,and the basic of agriculture is grain production.Therefore,food production becomes the eternal theme of the production and development of a country.Grain production is not only related to the National People's livelihood and stable development of the overall situation,but also related to national economic development,social stability of the global major strategic issues.As a large agricultural country and a country with a large population,the production of grain is very important.Jiangsu Province is located in east China and the world granary since ancient times,there have been "Su Chang harvested,and the world can eat enough" reputation.The study of grain production in Jiangsu Province is of great significance to guide grain production,ensure grain production and supply,stabilize grain price and ensure national food security.Based on the annual grain production in Jiangsu province,the factors influencing grain yield in Jiangsu Province were analyzed by correlation analysis and multivariate regression method.The main structure of the thesis is arranged as follows:In chapter 1,an introduction is devoted to review the background and the current situation related the dissertation.In chapter 2,based on the statistical data of the grain production in Jiangsu Province,this chapter gives the nine influential factors of grain production in Jiangsu province,and the related dates are consolidated and analyzed.In chapter 3,the linear regression model of grain yield in Jiangsu Province is established by regression analysis and correlation analysis,and the parameter estimation and hypothesis test of the model are carried out.In chapter 4,the multivariate regression model of grain yield in Jiangsu Province is established,and the model is analyzed and tested by SPSS.At the same time,the model is applied to actual production statistics,which verifies the validity of the model.In chapter 5,the summary and discussion of this dissertation are given,as well as the outlook of future work is discussed.
