- Abstract:
- Based on the principle of DPSIR model, driving force, pressure, state, effect, and response were selected to establish an index system for analysis of sustainability of the dryland farming with limited irrigation in Tongxin, Ningxia Hui Autonomous Region. The index system was expected to reflect the relationships among all the indices. An analytic hierarchy process and an entropy method were used to determine weights of every index and calculated the comprehensive evaluation index of ecological sustainability. The sustainability index of the dryland farming system with limited irrigation in Tongxin County always increased from 2005 to 2008. The sustainability state improved from good to very good level, which showed that the general sustainability was fair good because of the implementation of limited irrigation project. The order of indices was: 2008(0.924 5)>2007(0.851 9)>2006(0.710 3)>2005(0.572 4). This method combined DPSIR model and revised entropy method, which provided a new tool for ecological sustainability evaluation.
