本研究对《中国统计年鉴》各省的大田作物的不同种类,根据2006—2011年报导的秸秆系数的实测值,研究确定各省市自治区(除港、澳、台外)各类大田作物的秸秆系数取值,以数学模拟取值法对水稻、小麦和玉米3大作物进行取值,以相同或相似地区平均取值法、同类作物取值法确定其他作物取值。结果表明:水稻的秸秆系数取值变幅为0.74~1.33,全国平均值为1.04。小麦的变幅为1.05~1.41,全国平均值为1.28。玉米的变幅为0.93~1.30,全国平均值为1.07。豆类和薯类的变幅分别为1.13~1.86和0.42~0.75,全国平均值分别为1.35和0.53。黄红麻和棉花的秸秆系数的变幅分别为1.22~2.23和2.41~4.09,全国平均值分别为1.73和2.87。花生、油菜和芝麻的变幅分别为0.85~1.43、2.57~3.17和1.78~2.23,全国平均值分别为0.99、2.90和1.89。甘蔗的秸秆系数在各省统一取值为0.34。甜菜和烟草的变幅分别为0.18~0.67和0.49~0.92,全国平均值分别为0.37和0.66。“其他谷类”、“其他油料”和“其他麻类”的秸秆系数在各省取值均相同,分别为2.32、2.63和6.55。 In this study, the different types of field crops in each province of China Statistical Yearbook were studied. According to the measured values ​​of straw coefficients reported in 2006-2011, the straw coefficients of various types of field crops in provinces, autonomous regions, municipalities and autonomous regions (excluding Hong Kong, Macao and Taiwan) The values ​​of three crops of rice, wheat and maize were determined by mathematical simulation. The average value of the same or similar area and the value of similar crops were used to determine the value of other crops. The results showed that the value of straw coefficient of rice ranged from 0.74 to 1.33, and the national average was 1.04. Wheat amplitude 1.05 ~ 1.41, the national average of 1.28. Maize range 0.93 to 1.30, the national average of 1.07. The amplitude of pulses and tubers ranged from 1.13 to 1.86 and from 0.42 to 0.75, respectively, with national averages of 1.35 and 0.53, respectively. The kenaf coefficient of yellow kenaf and cotton varied from 1.22 to 2.23 and from 2.41 to 4.09, respectively. The national average was 1.73 and 2.87 respectively. The amplitude of peanut, rapeseed and sesame were 0.85-1.43, 2.57-3.17 and 1.78-2.23 respectively, with the national average of 0.99, 2.90 and 1.89 respectively. Straw coefficient of sugarcane in the provinces unified value of 0.34. Beet and tobacco amplitude were 0.18 ~ 0.67 and 0.49 ~ 0.92, the national average were 0.37 and 0.66. The “straw” values ​​for “other grains ”, “other oil ” and “other hemp ” were the same in all provinces and were 2.32, 2.63 and 6.55 respectively.

从数学教育角度分析,“口算能力”不能称之为数学技能,而是一种基本的数学应用素养,它不借助任何书面或具象的计算工具,是塑造学生抽象思维能力的重要途径。本文中笔者以小学低年级为研究对象,探索数学教学中口算能力培养的策略,以供广大教育工作者参考借鉴。  【关键词】小学数学;口算能力;低年级;策略  新一轮课程改革标准要求,小学阶段要突出学生的计算能力培养,提高口算训练的重视程度。严格地说,“口算”是一種
