Multi-measures to promote green urbanization

Urbanization is a dynamic process, and it is a multi-dimensional, non-linear dynamic process. Therefore, to study green urbanization, we should construct a scientific and reasonable macro-layout of urbanization according to the carrying capacity of resources and environment.

One is to ease the contradiction between people and land and take the road of compact urbanization. Urbanization without land can not be talked about urban construction, but land must be saved to ensure that the people of the whole country eat. From the international experience, there are two main types of urban scale expansion: one is "spreading pie", with London's urban expansion being the most typical; the other is advanced planning, which is generally the case for urban construction in late-developing countries. Both models exist in our country. Therefore, starting from the current situation of tension between people and land, we should put land conservation in an important position, form a city scale, industrial characteristics and architectural style that conforms to "saving priority, protection priority, natural recovery first" and has its own characteristics, retain "homesickness"; keep the "red line of cultivated land" and ensure food security.

The second is to promote industrial upgrading and improve environmental quality. Industrial upgrading should coincide with the process of urbanization and should not blindly pursue an innovative economy. It is the primary task of urban sustainable development to give full play to comparative advantages, select characteristic industries and cultivate them into new economic growth points. Efforts must be made from the aspects of industrial layout, structural adjustment, full life cycle resource and environmental management, technological innovation, and incentive and restraint mechanisms. With enterprises as the main body and intelligence, greening and marketization as the direction, the government will gradually promote green manufacturing through the formulation and implementation of industrial policies, promote the development of productive service industries, implement innovation-driven, import substitution and brand strategies, and promote the construction of smart cities and intelligent logistics. Complete the historical task of industrialization and urbanization in China with as little resource, energy consumption and pollutant emission as possible.

At the same time, it is necessary to play an important role in the development of the city and innovate ideas in urban planning, construction, operation management and old city reconstruction. Give full play to the energy-saving and emission reduction effects of "Internet +", promote the innovative application of information technologies such as Internet of Things, cloud computing and big data, promote cross-department, cross-industry and cross-region government information sharing and business collaboration, build smart cities, intelligent transportation and intelligent buildings, promote intelligent information applications and new information services, and promote the informatization of urban planning management, intelligent infrastructure, convenient public services, modernization of industrial development and refinement of social governance. Improve the level and efficiency of urban management and make the living environment better.

Third, green circular development is a fundamental measure for environmental protection. Land, water, energy, minerals, forests and so on are the basis of urban site selection and planning and construction. Mineral resources are mined from underground to produce necessities for residents. However, the earth's resources are limited and must be recycled. The management of the whole process of production, circulation and consumption must be strengthened to form a spatial pattern, industrial structure, trade structure, production mode and life mode that saves resources and protects the environment, greatly reducing the resource consumption intensity in the unit economy and laying a foundation for sustainable urban development. An important way of circular development is to develop circular economy. Circular economy should follow the principles of reduction, reuse and resource utilization, eat and squeeze everything, make the best use of everything, turn waste into treasure and harm into profit, change the traditional linear growth mode of "resource-product-waste" of mass exploitation, mass production and mass emission, extend the industrial chain according to the relationships of "upstream waste becomes downstream raw material","process coupling" and "resource sharing", upgrade the value chain, and shift from paying attention to exchange value to paying attention to use value. Form an intensive growth model of "resource-product-waste-renewable resources".

Fourth, form a long-term mechanism for green urbanization and strengthen urban environmental management. It is necessary to optimize the operation of existing urban functional zoning and transportation, strengthen the construction of underground comprehensive corridors, reduce the phenomenon of "zipper roads"; construct rain and sewage diversion and rainwater utilization systems, and build a "sponge city" capable of natural accumulation, natural infiltration and natural purification; In urban expansion and old city reconstruction, we should not demolish and build large buildings, but keep hutongs and characteristic residential buildings as much as possible, leaving necessary space for residents to shop, shop, entertain and exercise; Make full use of information technology, gradually build smart cities, improve urban management level; encourage the public to travel green and low-carbon, and improve the welfare level of residents with as little greenhouse gas emissions as possible without lowering the living standards of residents. Establish a governance structure involving government, enterprises and the public to modernize urban environmental governance capabilities. The government should create a social atmosphere in which everyone abides by the law and consciously controls pollution and protects the environment. A livable urban environment requires the awakening and action of residents, starting from things around them, such as picking up "vegetable baskets" and recycling packaging materials, and actively participating in public welfare activities, such as garbage classification, public health care, afforestation, etc. In the historical process of moving towards the "two centuries" and realizing the great rejuvenation of the Chinese nation, the "Chinese Dream" will realize the environmental goal of blue sky and green water, and enter a new era of ecological civilization as soon as possible.
