摘要:
耕地生态安全评价对改善耕地生态系统安全状况、促进耕地可持续利用具有重要的现实意义。以西安市为研究区域，采用压力—状态—响应模型，构建了基于能值理论的耕地生态安全指标评价体系，采用组合赋权法来确定指标权重，测度了2001—2012年西安市耕地生态安全水平值及变动趋势，并采用多元线性回归模型分析了耕地生态安全的影响因素。结果表明：西安市耕地生态安全值总体波动趋势为：2001—2007年耕地资源由较安全区下降至安全临界区，在2004年出现一次波动；2007—2010年耕地资源安全评价值呈上升趋势，且达到最高值，耕地生态状况由安全临界区跨越到较安全区；2010—2011年耕地资源安全状态下降至安全临界区，幅度较大，2012年虽有升高，但仍然处于安全临界区。提高人均能值产出、增加农业财政支出比例和严格管控建设用地占用耕地是改善西安市耕地生态安全的重要措施。
Abstract:
Ecological security evaluation of cultivated land has the important practical significance to improve the cultivated land situation and promote the sustainable utilization of cultivated land. We established evaluation index system of cultivated land ecological security based on P-S-R model and evaluated the cultivated land ecological security during the period from 2001 to 2012 by using combination weighting method in the range of Xi’an,and the multiple linear regression was carried out to find the driving forces on cultivated land ecological security with SPSS software. The results showed that the evaluation value of cultivated land resources changed from the relatively safe area to safety critical region during the period from 2001 and 2007, there was a wave in 2004; The evaluation value increased during the period from 2007 to 2010, and reached up to the highest levels in 2010, cultivated land ecological situation changed to the safety critical region from the relatively safe area; The cultivated land resources safety state changed to the critical safety region in 2011, it had improved slowly in 2012, but still belonged to the safety critical state. Therefore, improving the output of per capita energy, increasing the proportion of agricultural financial expenditure and controlling the construction of farmland are all the important measures to improve the ecological security of cultivated land in Xi’an City.
