Temporal-Spatial Evolution of the Urban Ecological Footprint Based on Net Primary Productivity: A Case Study of Xuzhou Central Area, China

The urbanization process all over the world has caused serious ecological and environmental problems which have recently become a focus for study. Ecological footprint analysis, which is widely used to assess the sustainability of regional development, can quantitatively measure the human occupation of natural capital. In this study, the ecological footprint based on net primary production (EF-NPP) and MODIS data were used to measure the ecological footprint in Xuzhou central area from 2005 to 2014. The results showed that from 2005 to 2014, the per capita ecological footprint increased from 1.06 to 1.17 hm2/person; the per capita ecological capacity decreased from 0.10 to 0.09 hm2/person; the per capita ecological deficit increased from −0.96 to −1.09 hm2/person; and the ecological pressure index increased from 6.87 to 11.97. The composition of the ecological footprint showed that grassland contributed most to the ecological footprint and deficit, and cultivated land contributed most to the ecological capacity. The spatial distribution of the ecological footprint changed significantly, especially in the expansion of the area of lower value. The ecological capacity and deficit changed little. The ecological situation in Xuzhou central area was unbalanced. Based on this study, Xuzhou city was recommended to control the increase of the ecological footprint, improve the ecological capacity and balance the ecological pattern for sustainable development.

An increasing number of nature reserves are being invaded by various development and construction activities, such as energy, resources, and transportation facilities. The ecological footprint model, which enables a quantitative assessment of ecological sustainability, can assess whether human consumption at various spatial scales falls within the regenerative capacity of the biosphere. Based on the traditional ecological footprint evaluation model: the Global Agro-Ecological Zone (EF-GAEZ model), this study proposes an improved ecological footprint model based on net primary productivity (EF-NPP model) and its validations. In this study, the status of ecological footprints and the ecological carrying capacities of 319 national nature reserves in 2010 is explored, and the changes in ecological surpluses and ecological deficits from 2000 to 2010 are analyzed. The ecological footprint per capita and the ecological carrying capacity per capita calculated by the two models were mostly consistently at the same level (more than 68%), which indicated that the ecological footprint per capita and the ecological carrying capacity per capita of the two models followed the same rule. The EF-NPP model can reflect the change in the global climate, the degradation of the soil, and the progress of the technology.

The paper calculates ecological footprint per capita and ecological capacity per capita in the Jilin province during 1998 and 2010 by using the ecological footprint theory, and analyzes the dynamic changes of ecological footprint per capita and ecological capacity per capita, and obtains development prediction model of ecological footprint per capita and ecological capacity per capita based on grey prediction model. The results indicate the ecological footprint per capita had increased continuously from 1.7841 hm2 per capita to 3.2013 hm2 per capita between 1998 and 2010. During this period, ecological capacity per capita dropped from 1.3535 hm2 per capita to 1.3028 hm2 per capita. Ecological deficit had increased from 0.4306 hm2 per capita to 1.8985 hm2 per capita that showed that the development of Jilin province was in an unsustainable status. The gray prediction model shows the ecological footprint per capita in the Jilin province will increase from 3.4833 hm2 per capita to 5.7022 hm2 per capita between 2011 and 2020, ecological capacity per capita will drop from 1.2978 hm2 per capita to 1.2676 hm2 per capita and ecological deficit will increase from 2.1855 hm2 per capita to 4.4346 hm2 per capita.

The Relationship

With the rapid development of tourism in“3+5” urban agglomeration, more and more attention is paid to ecological security triggered by tourism wave. Taking Loudi City in urban agglomeration as an example, conduct empirical study on the application of ecological footprint theories and methods on the quantitative evaluation of sustainable development of regional tourism. The results show: tourism ecological footprint per capita of Loudi was 768.9881×10-5hm2 in 2009 in which transportation taking 55.3156% is the maximum, and food consumption taking 39.7622% is the second one. Tourism ecological capacity per capita was 1520.5170×10-5hm2; tourism ecological surplus per capita was 751.5289×10-5hm2 and ecological security degree was 0.5057 which showed a common condition or could be said as a safer condition. However, with the rapid development of tourism, tourism ecological footprint of Loudi City shows an increasing trend year by year. We should coordinate well the relationship between tourism development and ecological environmental protection.

The componential method of ecological footprint is applied to estimate the ecological footprint of the Xi’an University of architecture and Technology (XAUAT) in 2011. An EF value for the urban public university was calculated as 21,398 global hectares with footprint of 0.71 global hectares and ecological capacity of 1.14 per capita. The components considered in this study include energy for the built environment (58%), food (34%), transportation (2.9%), water usage (2.5%) and waste discards (1.5%). Compared to the large urban universities in North America, university campuses in China show similar high density of land use while appear lower consumption levels and utilization rate of resources.

Reasonable Use

Reasonable use of land or not, directly related to the sustainable development of a country or region. This paper introduced the basic concept, calculation formula and method of the ecological footprint. We calculated the ecological footprint of Shenzhen by application of the ecological footprint model. The results showed that the per capita ecological footprint in Shenzhen in 2011 was approximately 2.486 hm2, while the per capita ecological capacity was approximately 0.0597 hm2, the per capita ecological deficit was approximately -2.433 hm2, and the ecological footprint is about 47.33 times greater than the ecological capacity. Finally, we discussed the limitations of applying the ecological footprint model to judge the sustainable use of land in this paper.
