The second principle is biological and ecological diversity. Biological and ecological diversity in Beijing, Tianjin and Hebei and its surrounding areas is an important guarantee for ecosystem security. Water and wetland ecosystem can keep the water balance in the basin, replenish groundwater and optimize the natural environment; Forest and grassland ecosystems have the functions of windbreak and sand fixation, flood control and soil conservation, and climate regulation; Farmland ecosystem can maintain agricultural ecosystem. Therefore, we must ensure biodiversity, which is also clearly stipulated in the Beijing-Tianjin-Hebei coordinated development plan.
The third is the principle of unified planning and legal control. Unified planning refers to the strict implementation of the "Beijing-Tianjin-Hebei coordinated development planning outline" and other related planning. Control according to law, including space control, industrial structure control, negative list control of industrial access, and urban growth boundary control.
The fourth is the principle of functional partition and classified control. There are many districts in Beijing, Tianjin and Hebei, and each district has its own functions, including ecological district, industrial district, agricultural district, living district, cultural and educational district and commercial district. There are functional partitions to control different ecological environments according to different functional partitions. In accordance with the overall requirements of optimizing key points, restricting and prohibiting development, we will clarify the key points of economic and social development in different regions and rationally plan the scale ratio of towns, agriculture and ecological space.
Fifth, the principle of paying equal attention to incentives and constraints. Through strict environmental access, environmental standards, total control, environmental assessment and other management measures, strengthen government control and restraint, standardize development and construction behavior. Through policies and measures such as price, finance, fees and finance, we will guide and standardize the environmental behavior of enterprises and implement environmental protection responsibilities.
Sixth, the principle of combining coordinated protection with autonomy. The guarantee and development of Beijing-Tianjin-Hebei integration must have some common requirements, but each place also has different situations and different problems, so it is necessary to give full play to the local initiative and creatively solve the problems.
Legal basis: Article 10 of People's Republic of China (PRC) Environmental Protection Law stipulates that the competent department of environmental protection in the State Council shall exercise unified supervision and management over the national environmental protection work; The competent department of environmental protection of the local people's governments at or above the county level shall exercise unified supervision and management over the environmental protection work in their respective administrative areas.
The relevant departments of the people's governments at or above the county level and the military environmental protection departments shall, in accordance with the provisions of relevant laws, supervise and manage environmental protection work such as resource protection and pollution prevention.
