统计计算及资料整理农村能源以数量大、种类多、定量性强为突出统计特点,因此如何对统计对象进行计算,是保证统计精度的关键。本讲就几个常遇到的资源统计计算方法介绍如下: 一、秸秆 Q总=Q谷×m×μ×·Q总——秸秆折成标准煤总量;m——为谷草比,是每亩秸秆产量与谷物产量比值,m值可以实测,无实测值时也可以查表(一)值;μ为折标煤系数,可以实测,先测出每种秸秆热值,然后除以7000大卡则为折标系数,无实测能力的也可查表(一)。
Statistical calculation and data compilation Rural energy is characterized by a large quantity, a large variety and a strong quantitative nature. Therefore, how to calculate the statistical objects is the key to ensure the statistical accuracy. This talk on several frequently encountered resources statistical methods are described below: First, the total straw Q = Q Valley × m × μ × Q total - straw converted into the total amount of standard coal; m - as straw ratio, is The ratio of straw output to grain yield per mu, m can be measured, no value can also check the table (a) value; μ for the standard coal coefficient can be measured, first measure the calorific value of each straw, and then divided by 7000 Kcal is a discount factor, no measured capacity can check the table (a).
