摘　　要：维护土地生态安全,有利于保障土地资源可持续利用。以合肥市为例,采取PSR模型,从压力、状态、响应三个维度,共选取19个指标,构建合肥市土地生态安全评价指标体系,并对2011~2020年合肥市土地生态安全指数进行评估。研究发现,2011年至2020年,合肥市土地生态安全压力指数和状态指数变化幅度较小,土地生态安全响应指数从0.0819上升至0.3091,土地生态安全综合指数十年间增长50.81%。提出完善土地法律法规,强化土地行政管理措施;坚持土地绿色发展理念,科学合理规划土地利用;强化相关宣传力度,提高群众生态保护意识等对策建议。Maintaining land ecological security is conducive to ensuring the sustainable use of land resources.Taking Hefei as an example,with the PSR model,this paper selects 19 indicators from three dimensions of pressure,state and response to construct the evaluation index system of land ecological security,and then evaluates the land ecological security index of Hefei from 2011 to 2020.The land ecological security pressure index and state index in Hefei show a small changing range within the 10 years,with the land ecological security response index from 0.0819 to 0.3091,and an increase by 50.81%for the land ecological security comprehensive index from 2011 to 2020.The countermeasures on the land ecological security in Hefei include improving land laws and regulations to strengthen land administration measures,adhering the concept of green land development to plan scientifically and rationally the land use,strengthening relevant publicity efforts to improve the people's awareness of ecological protection.
