“六五”时期我国养猪生产辩析

A ANALYSIS OF THE NATIONAL SWINE PRODUCTION DURING THE PERIOD OF 1981--1985

用生物统计的原理和方法分析了我国“六·五”期间养猪生产状况。此期间我国养猪生产的总趋势是好的,而地区发展极不平衡。养猪生产力指数、人口产量指数和人口养猪头数指数三项指标均表明,江苏、湖南、浙江三省高于全国平均水平。四川省产肉量最高,主要是因为养猪头数多,养猪生产力指数却很低。这种分析是调整我国畜牧业结构的重要依据之一。

The national swine pnoduction during the period from 1981 to 1985 is analysed by means of the principle and method of biostatistics. The general aspect of swine production is good during the period, but the differences among provinces are extremely significant. The three indexes of swine productive Force (SPF), Meat Output per Capita Pig Quantity per Capita show that the three provinces of Jiangsu,Hunan, ZheJiang are in the leading position. Although Sichuan produces the largest quantity of meat as it has the biggest number of pigs,its SPF is low.The above analysis is one of the impnrtant bases for the adjustment of the national animal husbandray structure.
