摘要
Abstract
To verify the scientific rationality of the results of cultivated land productivity calculation, and in order to further improve the existing "technical specification of agricultural productivity calculation" , based on average elevation data and grain yield data within the county, the literature material method, the method of comparative analysis, the method of regression analysis were adopted. Based on the analysis of the results of cultivated land productivity calculation and farmland classification in Chongqing, the analysis and calculation of macrographic examination were carried out for calculation results of cultivated land productivity in Chongqing. The results indicated that there were significant linear regression relations among county grain overall yield and the theoretical, realizable, practical productivity. From the perspective of regression coefficients, the practical productivity is more close to the grain yield, followed by the realizable productivity capacity and finally the theoretical yield. County average elevation had obvious linear regression relationships with average elevation-the theoretical, realizable and practical per unit area yield, they were all influenced by the altitude, and the per unit area yield in above three levels all tally with the actual situation.关键词
