广东省能流图与能源平衡分析

改革开放30年来，广东省已成为中国经济最发达的地区之一，经济的快速发展和大规模城市化建设也给能源供应和环境保护带来巨大压力。为了保障能源的充足供应和环境、经济的可持续发展，有必要从能源供给、转换、消费等方面对广东省能源平衡的全过程进行分析。根据2007年广东省能源平衡表．绘制出2007年广东省能流图。广东省能源消费中化石能源比重偏高，以煤炭、石油和天然气为主。而资源丰富的可再生能源比重偏低；能源消费总量增长迅速，对外依存度高，能源安全保障难度高；化石能源消费还带来了环境恶化和气候变化；火力发电效率与先进国家相比还有提高的空间。广东省工业部门消耗的能源最多，其次是交通运输和仓储邮政业。再次是城镇和农村居民生活，此外广东省对油品和电力等优质能源的需求也迅速扩大。鉴于此，建议在广东本地开发低碳新能源。包括核能、新能源与可再生能源等；充分开发利用国内国外两种资源、两个市场，进一步加强能源运输传送能力建设；提高火力发电效率应以技术改进为主，以优化燃料构成为辅；在工业上推进节能高效先进技术的应用，加快第l_产业的发展，在交通上推进高效率智能低排放的运输方式，鼓励居民采用并不降低舒适度的低碳生活方式和生活习惯。

Analysis of Guangdong Province's Energy Flow Chart and Energy Balance

Guangdong province is now one of the most developed regions in China after 30 years of growth since the start of reform and opening-up.Rapid economic growth and large-scale urbanization construction have also created enormous pressure for energy supply and environmental protection.To ensure an adequate energy supply and sustain the growth of economy and the environment,it is necessary to analyze all the factors affecting the province＇s energy balance including energy supply,conversion and consumption.Researchers mapped an energy flow chart based on Guangdong province＇s energy balance sheet in 2007.Fossil fuels,principally coal,petroleum and natural gas,accounted for a large proportion in the province＇s energy mix,while the percentage of rich renewable energy resources ergy consumption was very fast and the province the difficulty of ensuring energy security.The use was relatively low.The growth of Guangdong province＇s enhighly relies on import to meet its energy needs,adding to of fossil fuels has also resulted in a deterioration of the environment and climate change.The efficiency of coal-fired power generation in Guangdong province is still lower than that in developed countries.Industrial sectors are the biggest energy consumers province,followed by the traffic and transportation and storage and postal industries.The third in Guangdong largest energy consumer is the residential sector.The province＇s demand for high-quality energy sources such as refined oil products and electricity is also expanding rapidly.Given this situation,we suggest Guangdong province develop low-carbon energy sources,including nuclear power,new energy and renewable energy sources.Other measures include making full use of resources and markets both within and outside of China,strengthening the con- struction of energy transportation capacity ,raising the efficiency of coal-based power generation by conducting technical upgrades as well as optimizing the fuel mix, pushing the application of energy-efficient technologies in the industrial sector,accelerating the development of the third industry ,promoting the introduction of effi- cient,intelligent and low-emission traffic and transportation means and encouraging residents to lead a low- carbon life that does not compromise the comfortability of life.
