1 Practical significance of developing low-carbon economy in Pengshui County
(1) Developing a low-carbon economy is an inevitable choice made by Pengshui in combination with its own characteristics and the construction of an ecological protection development zone. The Third Plenary Session of the Fourth Session of Chongqing Municipal Committee put forward the strategy of five functional areas, positioning Pengshui and other six districts and counties in southeast Chongqing as "ecological protection and development areas", and demanding that Wuling Mountain be built into a highland for green economic development, an important ecological barrier, a folk culture eco-tourism belt and a demonstration area for poverty alleviation and development. Pengshui must firmly grasp this historical opportunity, promote the construction of ecological protection development zone, and embark on a road of transformation and development and green rise.
(2) Developing low-carbon economy is the fundamental way for Pengshui to relieve the pressure on resources and environment. At present, Pengshui's energy consumption is highly dependent on foreign countries. At the same time, the energy consumption structure dominated by coal and the economic structure dominated by heavy chemical industry have increased the pressure to develop environmental capacity. Taking low-carbon economy as the strategic goal of development is the fundamental way for Pengshui to achieve leap-forward development under the constraints of resources and environment.
(3) Developing low-carbon economy is an important measure to promote the coordinated and healthy development of urbanization and industrialization in Pengshui. Pengshui is in the early stage of industrialization, and the transformation of the old city and the construction of the new city are carried out simultaneously. The next ten to twenty years will be the peak of industrialization and urbanization in Pengshui County, and this period will also be the most serious period of environmental resources destruction and pollution in the process of undertaking industrial transfer and large-scale urbanization. Therefore, Pengshui must pay attention to planning and top-level design, and handle the relationship between economic and social development and ecological environment management.
(4) Developing low-carbon economy is an effective guarantee to promote the industrial transformation and upgrading in Pengshui County. At present, the proportion of industry and service industry in Pengshui County is low. In the future, agriculture will further develop in the direction of modern agriculture, and the development of service industry will mainly rely on tourism. The greater space for industrial transformation and upgrading in Pengshui County comes from the rapid development of industry. New industrialization must take ecological protection as the premise, and minimize the impact of economic development on resources and environment through circular cleaning and green low-carbon production. Under the background of low-carbon development, the effective combination of Pengshui's low-carbon energy advantages and regional mineral advantages will provide support for industrial upgrading.
2 Pengshui low-carbon economic development status
2. 1 pengshui low-carbon economic development achievements have initially appeared.
(1) Pengshui County has carried out pollution prevention and control by implementing the "five major actions" of environmental protection, and the ecological environment quality has been continuously improved. Southeast Chongqing took the lead in starting PM2.5 monitoring, and the excellent rate of air quality in the county was 94.5%. Rebuild and expand the county sewage pipe network, and build more township sewage treatment plants and domestic garbage collection and transportation systems. The water quality compliance rate of centralized drinking water sources is 100%, and the water quality of Wujiang River and Yujiang River meets the national Class III surface water quality standard. Comprehensively standardize the order of forestry administration, close 45 wood processing enterprises, complete all kinds of afforestation/kloc-0.6 million mu, and increase the forest coverage rate to 49%. Eliminate backward production capacity and reduce energy consumption per unit of GDP by 3%.
(2) The industrial structure is adjusted and upgraded, and the industrial scale is constantly expanding. By the end of 20 13, the proportion of three industries in Pengshui was 18.6:44.2:37.2. Held a national promotion meeting for poverty alleviation of sweet potato industry in hilly and mountainous areas, and successfully established a Mowei mountain-level modern agricultural park. Successfully introduced Taiji Group, a top 500 enterprise in China, to build a 100 billion-level health food industrial park; Hydropower generation has exceeded 6 billion kWh; Industrial added value growth11.7%; Completed tourism investment of 800 million yuan; Build a special agricultural product exhibition center, develop exhibition economy, activate urban and rural consumption, and complete the total retail sales of social consumer goods of 5 billion yuan, an increase of 14%.
2.2 The main problems in Pengshui's development of low-carbon economy at present
First, the lack of low-carbon industries and project support. Pengshui has not yet formed a continuous low-carbon industrial system. As a symbol of low-carbon industry, seven strategic emerging industries have not formed a scale in Pengshui. Second, there is a shortage of technical talents, and basic work such as low-carbon statistics and testing lags behind. Third, clean energy, minerals and tourism resources are abundant, but the problem of rational utilization of resources is outstanding and the ability of low-carbon integration is relatively insufficient. Pengshui County is rich in hydropower resources, mineral resources and forest resources. Shale gas reserves are huge, accounting for one-third of Chongqing, and the development prospect of clean energy is broad. If Pengshui develops rich mineral resources by using clean energy with huge reserves, it will make great achievements in emerging industries. But at present, Pengshui's ability to integrate these resources into low-carbon development is relatively insufficient.
3 Pengshui County, low-carbon economic development and pilot city construction countermeasures and suggestions
3. 1 Promote industrial low-carbon development with institutional innovation and scientific and technological innovation
(1) Vigorously develop low-carbon power with hydropower construction as the main body. Pengshui County is the only "water conservancy and energy base county" in Chongqing, with water resources of 6.5438+0.07 million kilowatts and hydropower development capacity of 2.3 million kilowatts. By 20 15, the total installed capacity of Wujiang Pengshui Power Station will reach1750,000 kilowatts, with an annual power generation of 6 billion kWh, which is the core support for the development of hydropower industry in the county. Because Pengshui's energy structure is mainly hydropower, it has a unique low-carbon advantage in industrial electricity consumption and can be used to deal with the problem of high energy consumption. Secondly, seize the opportunity of Chongqing as a pilot city for carbon emission trading and carry out policy and system innovation. As a low-carbon pilot city, one of the tasks of Chongqing is to compile the national greenhouse gas emission inventory. We can learn from foreign experience, use smart grid technology to obtain the energy structure data of electricity, formulate the system of linking the energy structure and price of electricity with carbon tax, and determine Pengshui's energy advantage from the rules.
(2) Take shale gas exploration and development as an opportunity to build a clean energy base. Pengshui shale gas has become a key development project in Chongqing. By 2020, the accumulated investment will be 654.38+0.2 billion yuan, with an annual output value of 4.2 billion yuan. Shale gas power generation is a clean energy source. Using the surplus of mining and transportation to generate electricity has a small carbon emission coefficient, which is conducive to low carbon. Construction of LNG utilization device, production of household and industrial LNG, in addition to self-use, further development of clean energy, supporting Chongqing natural gas vehicles. Build a shale gas chemical park, convert fossil energy into industrial raw materials, and further reduce the carbon emissions of Pengshui industry.
(3) Using mineral resources to process low-carbon energy products. Pengshui has preliminarily proved 23 kinds of mineral resources. Among them, there are nearly 10 species with good grade and large reserves, and the reserves of fluorite, magnesium ore and barite all rank first in the city. Therefore, Pengshui should develop and utilize mineral resources to process low-carbon energy products, such as using silicon materials to produce solar energy application devices and using fluoride salts to produce new energy application devices.
(4) Vigorously promote the development of biomass energy. Actively promote biomass energy projects and plan small biomass thermal power plants, biomass diesel processing production lines and organic fertilizer plants. Actively promote straw power generation and garbage incineration power generation projects, and explore straw comprehensive utilization projects. Develop biogas, biomass solid briquette fuel and biomass gasification to provide efficient and clean living fuel for rural areas. Comprehensively promote rural biogas construction, adjust rural energy structure, adhere to the "one pool and three reforms" (biogas digesters, toilets, kitchens) as the focus, promote the project of enriching the people in ecological homes, and promote the application of biogas ecological agriculture model according to local conditions. Villages and towns shall establish biogas management service outlets to be responsible for the follow-up services of biogas digesters construction in this project area, including troubleshooting, operation procedures and technical training.
3.2 Urbanization as an opportunity to promote low-carbon development in old and new urban areas.
(1) The old city reconstruction is based on the principle of organically combining functional requirements with traditional features. In accordance with the principle of "eliminating danger, leaving blank space and increasing greening", we will promote the transformation of the old city in an orderly manner. Functionally, it is necessary to integrate the development concept of low-carbon cities and promote the use of new energy and energy-saving materials. Considering the limited land in Pengshui, we should avoid large-scale demolition and construction, and adopt small-scale and gradual improvement methods.
(2) Build a new city Indishui, which aims at a low-carbon ecologically livable new city. It has a unique demonstration role for Chongqing's urbanization transformation and development to build Indishui new city into a low-carbon ecological livable new city. Based on the encrypted road network, the new town planning should rationally lay out the construction of urban backbone road network, urban water supply and drainage, communications, electricity and gas projects, flood control projects, municipal squares, urban greening, etc., so as to lay the foundation for building low-carbon Pengshui. The corresponding carbon emission reduction targets have been formulated in the aspects of total carbon emission reduction control in construction, transportation and production.
(3) Optimize the planning of major industries in the city and improve the management system of key industries. The construction industry is the focus of carbon emissions. The construction planning should implement the relevant laws, regulations and technical standards for building energy efficiency, innovate the working mechanism, and effectively ensure the effective implementation of mandatory standards for building energy efficiency in the design and construction stages. At the same time, establish and improve the evaluation system of energy conservation and emission reduction targets for highways, waterways and urban passenger transport. Strengthen the responsibility of energy conservation and emission reduction of transportation departments and enterprises at all levels, decompose and implement the energy conservation and emission reduction targets of the industry, and form a comprehensive assessment method and corresponding reward and punishment measures for the competent departments of the industry and key enterprises.
