摘要
基于土地利用的多功能性理论,构建"三生用地"效益的三级指标体系;运用改进的TOPSIS方法分析了晋城市2006—2013年"三生用地"效益的动态变化;运用协调度模型评价"三生用地"子系统的协调程度。结果表明:在2006—2013年期间,晋城市"三生用地"综合效益及各个子系统效益总体均呈上升趋势;其中,生态生产用地效益在整个研究期间均保持增长的趋势,其余各个子系统出现一定的波动;在整个研究期间,"三生用地"子系统效益的协调度呈现双"U"的形状,每一年度的协调度均在0.95以上,各个子系统保持着高度协调。最后提出推广农业创新技术以提升耕地抵抗自然灾害能力、生活方面倡导人们改变生活方式、工业生产过程中运用脱硫技术等措施改善生态环境的建议。
We evaluated the land use efficiency of ecological-living-productive land from 2006 to 2013 in Jincheng,and established the indictor system containing three levels indictors.The indictor system was based on the theory of land multiple functions.The method of TOPSIS and coordination model were used to evaluate dynamic change process of the land use efficiency and coordination development,respectively.The results showed that both the comprehensive efficiency of ecological-living-industrial land and the efficiency about land use subsystems improved throughout the study period;the efficiency about subsystems was fluctuating without the efficiency of ecological-productive land that increased continuously;the chart about coordination development of ecological-living-productive land subsystems was in the shape of‘double U＇;and the subsystems coordinated highly with the degree of coordination in each year was great than 0.95.Agricultural innovative technology should be promoted to enhance the ability of resisting natural disasters for cultivated land,people was advocated to change their lifestyles,and utilization of the desulfurization technology in the industrial production process can improve the ecological environment.
