摘  要:
为喀斯特地区土地优化利用、改善土地生态安全水平提供理论和实践参考,以贵州省遵义市为例,采用三角模型法,从经济可行性、社会可接受性及资源环境合理性建立土地生态安全评价指标体系,通过构建的三角模型对遵义市2005—2015年间的土地生态安全状态和趋势进行分析与评价。结果表明:2005—2015年遵义市土地生态安全水平经历不安全→弱安全→一般安全→很安全4个阶段,具有逐渐向非常安全发展的趋势。

摘  要:
To provide theoretical and practical references for optimal land utilization and improvement of land ecologic security level,based on the status of land use in Zunyi,in this paper the authors establishes the evaluation index system of urban land ecological security from economic feasibility,social acceptability and resource and environment rationality.Through the constructed triangle model,the authors analyzes and evaluates the status and trends of land ecological security during 2005-2015 in Zunyi.The results show that during the period of 2005-2015,the level of ecological security of land in Zunyi has undergone four stages:unsafe → weak security → general security → very safe,tending toward very safe gradually.
