摘要:
在构建盐池县粮食总产量评价指标体系的基础上，应用因子分析法首先对盐池县25a粮食总产量与影响因子进行分析与评价：影响单产的主要5个主成分，因子1由投入因子决定；因子2由光温因子决定；因子3由生育期因子决定；因子4由降水量因子决定；因子5主要由风害因子决定。各因子各自占的比例分别为38.7559%、17.9852%、10.8728%、11.8884%、10.4799%，盐池县粮食总产量主要是依靠第一因子。总体评价最好为2004年，最差为1984年。并针对盐池县粮食总产量发展的现状的提出相应的对策。
Abstract:
Based on the construction of evaluation indicators system of the total grain output in Yanchi county, firstly analysis and evaluation to 25 years of total grain production and influence factors in Yanchi county were carried out by applying factor analysis. The 5 main components influence grain yield. Component 1 was decided by the input factor,factor 2 by the light and temperature, factor 3 by the growth factor, factor 4 by the precipitation factor and factor 5 was by wind damage factors. The proportion of each factor was 38.7559%, 17.985 2%, 10.872 8%, 11.888 4%, 10.479 9%, respectively. Yanchi county’s total grain output was mainly depended on the first factor. The overall best assessment happened in 2004, the worst one occurred in 1984. At the same time, the corresponding countermeasures were proposed for the purpose of the current development situation of the total grain output in Yanchi county.
