Soil is a common crop environment growth condition. As an expert on soil protection, Zhou Jianmin submitted proposals on soil pollution prevention and protection and cultivated land protection at the National Two Conferences on many occasions. In view of soil pollution, Zhou Jianmin suggested that the relevant departments should formulate more reasonable standards. Scientific treatment to solve "soil disease". The biggest problem of soil pollution is unclear household background. At the same time, multisectoral management results in overlapping responsibilities and unclear boundaries. It is suggested that the third soil survey be carried out as soon as possible.



"Soil is not only related to our food security, but also to the whole ecological environment. It is suggested that the third national soil survey be carried out as soon as possible." At the panel discussion of the Standing Committee of the CPPCC National Committee, Zhou Jianmin, the Standing Committee of the CPPCC National Committee, said bluntly that soil census was imminent.




"Most of the data now used by researchers are from the second Soil Census in the early 1980s. In fact, over the past 30 years, China's soil has changed a lot, but there is no very detailed data. Zhou Jianmin said.



In April 2014, the National Soil Pollution Investigation Bulletin issued jointly by the Ministry of Environmental Protection and the Ministry of Land and Resources showed that the overall situation of the soil environment in China was not optimistic, with a total exceeding standard rate of 16.1%. Among them, the problem of cultivated land pollution was the most prominent, and the exceeding standard rate of soil sites reached 19.4%.



"It's scary, but it's not necessarily reliable." On the above data, Zhou Jianmin said that the prevention and control of soil pollution involves many departments, such as land and resources, agriculture, environmental protection, industry and so on. There are problems of cross-sectoral responsibilities and unclear boundaries.



Zhou Jianmin said that different departments now adopt different methods and standards, and the conclusions drawn from the survey are different, which will cause confusion. "Therefore, we need to unify standards and methods to ensure that we have real data."
