1990～2008年福建省农业废弃物产生量估算

摘要

Based on the data published in Fujian Statistical Yearbook, the amounts of various agricultural wastes produced in Fujian from 1990 to 2008 were obtained. The total waste of the crop straw was 8. 05 -10. 77 million tons. It declined gradually from 1990 through 2008. The straw from the food crops (I. E. , cereals) decreased most greatly: the rice straw by 30. 42% and wheat straw by 95%. On the other hand, the straw from the cash crops (except sugarcane) increased by 59. 99% from 1990 to 2005. The livestock manure increased gradually from 21. 66 to 32. 72 million tons over the years. Pig manure increased 1. 46 times from 1990 to 2005. Sheep manure increased 1. 46 times, but the cow manure declined by 32. 43%, from 1990 to 2008.%利用福建统计年鉴数据对福建省农业废弃物产生量进行估算.结果显示:1990～2008年,福建省秸秆资源总量呈下降的趋势,产生量为805.09～1 077.41万t,其中粮食作物(谷类)秸秆产量下降幅度最大,稻秸产量下降了30.42％,麦秸下降了95％,经济作物(除甘蔗外)的秸秆产量呈上升趋势,从1990年到2005年上升了59.99 ％；畜禽粪便资源总量呈上升的趋势,产生量为2 166.30～3 272.25万t,其中肉猪粪尿产生量从1990年到2005年增长了1.46倍,肉羊粪尿量增长了2.04倍,牛的粪尿量下降了32.43％.
