Black land is an extremely precious natural resource, which has important strategic significance and economic value. The black soil area in Northeast China is one of the three most fertile black soil distribution areas recognized in the world. It is an important national grain production base. The grain output accounts for about one quarter of the country and is the "ballast" to ensure national food security. The reporter learned from the Supreme People's Procuratorate that on May 24, the Supreme People's Procuratorate released relevant typical cases with the theme of "procuratorial organs protect black land according to law". It is reported that there are four typical cases released this time, including illegal mining by Wang and others, and illegal mining, concealment and concealment of criminal proceeds by Li; Heilongjiang Provincial procuratorate agricultural reclamation branch urged agricultural and rural departments to perform their duties of protecting fallow subsidy funds according to law; A case in which the procuratorial organ of Songyuan City, Jilin Province urged the agricultural and rural departments, forestry and grass departments to perform their duties of preventing and controlling alien invasive species according to law; Hulunbuir Procuratorate of Inner Mongolia Autonomous Region urged local governments to perform their duties of wetland protection according to law. This batch of typical cases mainly involve cracking down on the criminal acts of illegal mining and trafficking in peat soil according to law, protecting the national fallow subsidy funds, preventing and controlling alien invasive species, and strengthening the protection of wetland water and soil resources, which is of exemplary significance for the procuratorial organs to actively perform their duties according to law and strengthen the protection of black land resources. "Strengthening the protection of black land is an urgent need to safeguard national food security and secure the Chinese people's own jobs. It is of great significance to prevent soil erosion, reduce environmental pollution, improve the ecological environment and promote high-quality and sustainable development of agriculture." The procuratorial organs will conscientiously support the legal protection and win-win policy of illegal land processing and resource trafficking, and consciously support the procuratorial organs to protect and punish illegal land processing and resource trafficking in accordance with the law, We will effectively protect black land resources and the ecological environment and safeguard national food security.
