- Abstract:
- The relationship between land use ecology safety and human survival and development is extremely close, and land use ecology is the core idea of land use sustainable development. According to land use characteristics in Xi’an City, we selected 15 indexes from natural economic and social perspectives, and established the evaluation system from economic availability index (EI), non-social availability index (NSI), non resource environment appropriateness index(NREI), and carried out the dynamic assessment of the status and trend of ecologic safety of Xi’an City from 2005 to 2013 based on triangle model. The results showed as follows. The triangle model was appropriate in land ecologic safety assessment. The development of land ecologic safety of Xi’an City showed the positive trend, evolving from unsafety in 2005 to general safety in 2013. The trend of land ecologic safety of Xi’an City varied as the principle: from weak safety to strong safety to general safety to strong safety to weak safety. Overall, land ecologic safety of Xi’an City showed the more positive trend and its land use was becoming more appropriate.
