ECOLOGICAL FOOTPRINT-BASED ENVIRONMENTAL IMPACT ASSESSMENT OF STRUCTURAL ADJUSTMENT OBJECTIVES FOR OVERALL LAND UTILIZATION PLANNING-AN EMPIRICAL STUDY BASED ON LINXIANG CITY - Y. Z. Liu; X. Zhou; Y. Chen; Z. Zhang; L. L. Zhou (Journal of Animal and Plant Sciences, 2015)
The ecological footprint model is modified pursuant to the characteristics of the overall land utilization planning of Linxiang City to conduct the ecological footprint accounting of the structural adjustment objectives of the planned land. The results show that compared to 2005, the total ecological capacity will rise to some extent in Linxiang City by the end of the planning period, the total ecological profit/loss of consumption will change from an ecological profit to an ecological loss, the total ecological profit/loss of output will present a growing ecological deficit. The sustainable ecological loss will decline to some extent, but the degree of ecological sustainable development will be still maintained at a higher level. The research proves thatthe structural adjustment objective of the planning land determined in the overall land utilization planning of the city will alleviate the pressure on the ecosystem created by the implementation of the planning, and help increase the sustainable utilization level of the land ecosystem. The research concludes that the major way to further promote ecological sustainability of Linxiang City is to increase the resource yield rate, resource utilization rate and intensive land utilization, and control excessive population growth.
