【摘要】 研究目的:探索县域土地资源环境承载力变化特征,为县级土地利用总体规划的调整完善提供一定的理论依据。研究方法:采用极差变换法处理基础数据,均方差决策法赋指标权重,状态评价法确定土地资源环境承载力。研究结果:和林格尔县土地利用总体规划(2009—2020年)实施期间(2009—2015年),生态环境、社会与经济子系统承载力变化呈缓慢上升趋势;水土资源系统承载力变化幅度较大,稳定性较差;全县土地资源环境综合承载力呈现先升后降、总体呈上升且趋于稳定的趋势。研究结论:①本轮规划实施期间研究区土地利用与社会经济发展及生态环境趋于协调,使得土地资源环境承载力逐步提高;②今后继续在提高土地节约集约利用水平、提高资源利用效率、深化生态建设等多方面保证本县承载力水平的稳定。更多还原

【Abstract】 The purpose of this study is to study the change of land resources carrying capacity of county and provide theory evidence for the adjustment and improvement of the land use planning at county level.During the period of 2009—2015,the carrying capacity of the ecological environment and social and economic subsystem increased slowly,and the carrying capacity of the soil and water resources system in Helingeer varied greatly and the stability was poor.The method of range transformation is used to deal with the basic data,and the weight coefficient is determined by the mean square decision method.Finally,the environmental carrying capacity of land resources is evaluated by the method of state evaluation.The evaluation results reveal that the land use planning in Helingeer 2009—2020 implementation period shows a rise of environmental carrying capacity of land resources in the county after the drop,with the overall trend of becoming stable.Research conclusion:①During the implementation of the current plan,the land use and socio-economic development and ecological environment in the study area tend to coordinate,making the land resources and environmental carrying capacity gradually improved;②In the future,we should continue to improve the level of land conservation and intensive use,improve the efficiency of resource utilization,and deepen the ecological construction and other aspects to ensure the stability of the county’s carrying capacity.更多还原
