Abstract:

In this paper, we introduced the evaluation method of balance indicator and production indicator based on satellite retrieved net primarily production of vegetation that is implemented into a three-dimensional ecological footprint model.Using this model, we further calculated and analyzed the ecological carrying capacity and sustainable development ability of resources and environment in 2000, 2005, 2010, 2015, and 2018 in Guilin from the perspectives of space and time, using footprint breadth and footprint depth as the measurement unit and "national hectare".In addition, the utilization efficiency of natural resources in Guilin was quantitatively evaluated using the economic evaluation index (Gross Domestic Product, GDP) and ecological footprint index.The results showed that the ecological carrying capacity in Guilin increases slightly from 2000 to 2018, while the ecological footprint and ecological deficit both increase at first with the peak values appearing in 2010 and then decrease.Contribution rates of various land-use types to the per capita ecological footprint and ecological carrying capacity are quite different, and the demand and supply levels of all kinds of land in social and economic construction are unequal.The footprint breadth increases in all years except for 2005, and the footprint depth increases first and then decreases.The excessive consumption of natural resources is an important factor affecting the sustainable development of the ecological environment in Guilin.The ecological efficiency of natural resources in Guilin increases significantly from 2000 to 2018.After 2010, the tertiary industry gradually plays a major role in economic construction, with great economic development potential.
