中国畜禽粪尿磷素养分资源分布以及利用状况

The distribution of phosphorus resources and utilization of animal manure in China

参照中国有机肥料养分志计算粪尿资源量的方法,研究了2002年我国畜禽粪尿磷素养分资源的状况及其分布。结果表明:我国畜禽粪尿肥资源总量约为33亿t,提供磷(P)318.4万t,主要分布在山东、河南、四川、河北、广东、湖南等省。145.7万t粪尿磷资源作为有机肥回田,占粪尿磷资源总量的45.8%;而进入环境的磷约为172.7万t,占粪尿磷资源总量的54.2%。北京和上海粪尿磷资源总量不多,但其单位面积承载的磷却很高,分别为98.7kg/hm2和86.6kg/hm2。

The P amount in animal manure in 2002 was studied based on the calculating method in the book 'Records of Nutrients in Organic Fertilizer in China'. The results showed that the amount of animal manure in China was 3.3 billion tons and the total P amount in animal manure was 3.18 million tons. The P of manure was distributed in Shandong, Henan, Sichuan, Hebei, Guangdong and Hunan province. The P amount of animal manure which was collected and used in farm land was 1.46 million tons, which occupied 45.8% of the total P amount. While the P amount input into environment was 1.73 million tons, which occupied 54.2% of the total P amount. The P amount of animal manure in Beijing and Shanghai was less than other province, but the P amount per hectare was the highest, it was 98.7 kg/hm^2 and 86.6 kg/hm^2 respectively.
