Abstract
To evaluate the ecological level and energy consumption of Guangdong Province, by collecting the related data of energy consumption and land area from 2010 to 2019, the energy ecological footprint and net primary productivity were calculated. The study found that between 2010 and 2019, the energy ecological footprint of Guangdong increased from 119.77 million hm2 to 139.90 million hm2, while the net primary productivity increased slightly. Finally, the study analyzed the specific reasons for these changes.
Highlights
The shortage of ecological resources and environmental damage caused by the massive consumption of fossil energy make the problem of ecologically sustainable development more serious
Energy ecological footprint (EEF) is based on ecological footprint accounting, which refers to the total energy consumption of a certain area and the bio-productive land area occupied by its wastes
The energy terminal consumption data and various ecological land areas in this paper come from Guangdong Statistical Yearbook [4] and the official website of Guangdong Provincial Department of Natural Resources [5], the average low calorific value data of various energy sources comes from General Rules for Calculation of Comprehensive Energy Consumption (GB/T 2589-2008), and the carbon emission values from combustion or consumption of various energy sources are taken from 2006 IPCC Guidelines for National Greenhouse Gas Inventory[6]
Summary
The shortage of ecological resources and environmental damage caused by the massive consumption of fossil energy make the problem of ecologically sustainable development more serious. Sustainable development is the "golden key" to solve the current global problems, and the necessary prerequisite for realizing sustainable development is to attach great importance to the construction of ecological civilization and pay attention to the ecological economy at the same time. Before putting forward targeted countermeasures for the ecological environment of each region, it is necessary to evaluate the ecological situation and sustainability of the region objectively and accurately. After deepening the understanding of ecological footprint, Jason Venetouslis et al [3] first proposed to combine Net Primary Productivity(NPP) with the ecological footprint, and produced a new improved calculation model. Providing a reference for identifying the sustainable development situation of Guangdong Province, formulating urban construction strategies, and realizing sustainable development
