低碳沼气工程建设的生态经济效益核算研究——以广西恭城瑶族自治县为例
Ecological and Economic Benefit Accounting for Low-Carbon Biogas Project Construction——A Case Study of Gongcheng, Guangxi
摘要
Abstract
In the background of global warming and rapid urbanization, the economic-social-ecological sustainable development of rural areas has been constrained due to its blind role of energy intensive consumption. Biogas project provides a suitable clean energy consuming pattern, which has predominant advantages in optimizing energy-using structure, reducing environmental pollution, conserving natural resources, increasing farmers' income and promoting rural economic transformation, etc. The biogas demonstration project of Gongcheng Yao-Autonomous County of Guangxi is chosen as a study case. In this paper, we evaluate the carbon footprint, emission reduction effect, economic benefit and ecological value in the life cycle process of construction, operation maintenance and output consumption of an 8 m3 biogas tank. The results show that the substitution of coal, firewood, and straw can lead to a CO2 emission reduction of 1. 24 million tons. With a viewpoint of input-output value analysis from biogas' s construction to production process, each household can save 19,877 Yuan(RMB) through biogas consumption instead of fossil fuel and recycling of the wastes, which can bring 126 million Yuan(RMB) of total earnings for Gongcheng Country. Therefore, the biogas project is considered as an effective measure in promoting low carbon economy in rural areas and enriching the peasants for Gongcheng Country. Meanwhile, the direct economic-environmental-ecological effects of Gongcheng' s biogas project could be worthy of popularizing.关键词
