摘要
通过筛选确定各种系数,估算和比较了湖南的秸秆和畜禽粪便的资源潜力和开发潜力。结果表明:2016年湖南的秸秆资源总量为4 232.42万t;秸秆可利用量为3 267.43万t,折合标准煤为1 496.74万t;畜禽粪便总量4 900.95万t,尿液总量5 163.53,干物质资源量为1140.19万t;畜禽粪便干物质可利用总量为669.46万t,折合标准煤为316.37万t;湖南省农业资源废弃物可利用总量折标准煤超过1 800万t。对湖南农业废弃物的综合利用进行了分析,分析认为湖南农作物秸秆初步形成了肥料化、饲料化利用为基础,基料化、原料化利用为补充,能源化利用快速发展的秸秆综合利用格局;畜禽粪便利用以肥料化、能源化利用为主。
The correlation coefficient is helpful to evaluate the potential of agricultural waste resources in this area more accurately.Through screening and determining various coefficients,the resource potential and exploitable potential of straw and livestock manure in Hunan Province were estimated and compared.The results showed that the total amount of straw resources was 42 324 200 tons in Hunan in 2016.The available amount of straw was 32 674 300 tons,which was equivalent to 14 967 400 tons.The total amount of livestock and poultry manure was 49009500 tons,the total amount of urine was 51 635 300 tons,and the amount of dry matter resources was 11 401 900 tons.The total amount of dry matter available in livestock manure was 6 694 600 tons,equivalent to 3 163 700 tons of standard coal.The estimated amount of agricultural waste resources in Hunan is equivalent to over 1 800 000 tons of standard coal.The comprehensive utilization of agricultural wastes in Hunan Province was analyzed and evaluated based on the estimated results of resources.Hunan crop straw has initially formed a comprehensive straw utilization pattern based on fertilizer and feed utilization,supplemented by base material and raw material utilization,and rapidly developed energy utilization.The utilization of livestock manure is dominated by fertilizer and energy utilization.
