- 摘要:
- 根据DPSIR模型的原理，针对宁夏同心旱作补水农业可持续发展评价，从驱动力、压力、状态、影响及响应这5个方面来建立指标体系，力求能够反映出指标体系中各指标之间的关系；根据层次分析法和熵值法确定综合权重，对其指标进行赋权，并计算出生态可持续发展综合评价指数。同心县旱作补水农业体系2005-2008年可持续发展评价值一直上升，可持续状态从一般转变为良好到优秀。评价指数依次为：2008年（0.924 5）>2007年（0.851 9）>2006年（0.710 3）>2005年（0.572 4）。用DPSIR模型与改进熵值法的结合为生态可持续发展评价提供了一个新的方法。
- 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.
