Research on Sustainable Development Capacity of Yellow River Wetland Based on the Ecological Footprint Model - A Case of Dongying

The ecological footprint demand and ecological capacity for the six types of productive land during 2005~2010 are calculated using the ecological footprint model in this paper by taking Dongying City as the example, and the ecological deficit of Dongying City is thereby figured out. Based on this, the indicators such as the ecological footprint of 10k yuan GDP, the ecological pressure index, the ecological diversity index, and the social economic development index, etc representing the sustainable development are calculated and analyzed, to learn that it is not allowed to be optimistic about the ecological environment in Dongying in recent years, as the ecological deficit has increased year after year, and the ecological pressure has become heavier and heavier. However, it is learned through analysis of the ecological footprint of 10k yuan GDP and the social economic development index that under the situation when the ecological pressure on economic growth in the ecological economic system of Dongying is increased, a tendency exists for the consumptive and extensive economic growth pattern to gradually step towards the ecologically intensive pattern, but it is still required to make more efforts in the aspects of reducing the ecological footprint demand and improving the ecological capacity.
