西安市蔬菜秸秆资源化利用潜力分析
|
摘要
[目的]评价西安市蔬菜秸秆资源量的分布特性,充分认识西安市蔬菜秸秆资源化利用潜力。[方法]通过草谷比计算方法,对西安市蔬菜秸秆资源量进行全面系统的估算及其资源量分布。[结果]2017年西安市蔬菜秸秆理论资源量31.63万t,可转化为沼气5 502.84万m~3;阎良区蔬菜秸秆资源分布最大,占全市蔬菜秸秆资源量的29%。全市蔬菜秸秆蕴藏的养分含量也较大,氮含量、磷含量、钾含量分别达4 287.81、578.25、5 099.52 t,具有很大的利用价值。[结论]该研究为西安市蔬菜秸秆综合利用提供借鉴。
[Objective] The research aimed to evaluate the distribution characteristics of vegetable straw resources in Xi'an City,and fully understand the potential utilization of vegetable straw resources in Xi'an City.[Method]Through the grass-to-grain ratio calculation method,a comprehensive systematic estimation of vegetable straw resources in Xi'an City and its resource distribution were carried out.[Result]In 2017,the theoretical resource of vegetable straw in Xi'an is 316 300 t,which could be converted into biogas 5 502 840 0 m~3;the distribution of vegetable straw resources in Yanliang District accounted for 29% of the total vegetable straw resources in the city.The nutrient content of vegetable straw in the city was also large,and the nitrogen,phosphorus and potassium contents were 4 287.81,578.25 and 5 099.52 t,respectively,which had great utilization value.[Conclusion]This study provides a reference for the comprehensive utilization of vegetable straw in Xi'an City.
