摘  要：
[目的]基于景观生态安全格局的土地利用研究,为缓解人地矛盾、经济发展与生态保护提供科学依据。[方法]以成都平原与龙门山脉过渡带的四川省绵竹市为例,基于遥感和GIS技术,在提取和分析20a来土地利用变化及其地形因子响应基础上,以生态用地保护为目标,选取地形和土地覆盖类型为阻力因子,应用最小累计阻力模型构建景观生态安全格局。通过与土地资源现状的叠加,对不同景观安全水平的土地资源进行划分。[结果]研究区土地资源分为优先开发、适度开发、限制开发、禁止开发等4种类型,其面积分别达7 218.39,17 974.75,21 545.39,77 791.46hm2,并分析各类型土地利用特征,提出了相应的土地资源开发利用规划。[结论]基于景观生态格局理论与方法,提出的不同生态安全水平的土地用地规划,有利于区域生态安全保护和土地资源持续性利用。

摘  要：
[Objective]Land use was studied based on landscape ecological security pattern to provide a scientific basis for relieving the contradiction between the increasing population and limited land,and for economic development and ecological protection.[Methods]Mianzhu City of Sichuan Province which located in the transition zone from Chengdu plain and Longmen mountain was took as a case study,where the land use change and its terrain factors response were extracted and analyzed from 1995 to 2015,based on remote sensing imagery,technology of remote sensing and GIS.To achieve the goal of ecological land protection,terrain and land cover types were selected as resistance factors,the minimum cumulative resistance model was applied to landscape ecological security pattern based on GIS spatial analysis method.Upon the spatial overlay analysis of land use status and landscape ecology security patterns in Mianzhu City by GIS,land resources in different levels of landscape security were divided.[Results]Land resources of landscape security includedpriority,appropriate,limited,prohibited development,having acreages of 7 218.39,17 974.75,21 545.39,77 791.46hm2,respectively.The corresponding planning of land resources development and utilization was put forward based on the analysis of characteristics of each type land use in study area.The results can provide effective methods and means for regional ecological safety and reasonable development and utilization of land resources.[Conclusion]The land use planning whereon proposed by different ecological security level based on the theory of landscape ecological pattern and the corresponding method are conducive to regional ecological security protection and sustainable utilization of land resources.
