前言我国是一个农业大国,耕地面积不到世界总耕地面积的10%,但是我国人口众多,占世界人口总数的22%,我国在不断提高农产品产量过程中,不可避免的会对环境造成污染。根据相关的调查数据显示,我国农业源排放的COD逐年上升,已经达到全国COD排放基数的50%,此外,由于农药、化肥等的过量使用,导致土壤板结,严重降低了农产品的产量,阻碍了我国农业的可持续发展。因此,为了有效缓解环境污染,需要实
Foreword China is a big agricultural country with arable land less than 10% of the world’s total cultivated land. However, with a large population in our country, accounting for 22% of the world’s population, our country will inevitably pollute the environment in the process of continuously increasing the output of agricultural products. According to the relevant survey data, the COD of China’s agricultural sources has risen year by year, reaching 50% of the national COD discharge base. In addition, due to the excessive use of pesticides and fertilizers, soil compaction results in a serious decrease in the output of agricultural products, hindering Sustainable Development of Agriculture in China.
