摘要
土地持续利用是区域可持续发展的核心内容与重要基础,是推动区域经济可持续发展的重要保障。利用GIS和CLUE-S模型,以郑州市为研究区,以郑州市2000年土地利用现状数据为基础,模拟研究区在可持续利用情景下的未来土地利用变化情景,并运用层次分析法对研究区土地承载力和环境敏感性进行分析评价,在此基础上对郑州市土地可持续利用发展模式进行了探讨。研究表明:郑州市土地承载力水平偏低,土壤环境敏感性较高。在未来情景建设用地面积将明显增加的情况下,郑州市应优化土地利用结构,加大环境治理力度,改善生态环境,以促进土地资源的可持续利用,保障社会经济稳定快速发展。本研究可为理解土地利用系统的复杂性和动态性提供帮助,并为研究区今后的土地利用总体规划编制和土地可持续性管理具有指导作用。
Sustainable land use is the core and an important foundation of regional sustainable development,and is an important guarantee to promote the sustainable development of regional economy.Using CLUE-S(Conversion of Land Use and its Effects model)model based on GIS spatial analysis and statistics,this paper takes Zhengzhou City as research area,and simulates the future land use spatial change,in the scenario of sustainable land use,based on the land use map of Zhengzhou City in 2000.This paper discusses the development pattern on sustainable land use in Zhengzhou City,by evaluating land carrying capacity and environmental sensitivity in study area based on AHP(Analytic Hierarchy Process).As a result,the land carrying capacity in Zhengzhou City is low,and environmental sensitivity is high.So,the government of study area should optimize land use structure,improve the environment and the ecological environment,promote the sustainable use of land resources,protect the rapid development of social and economic stability.This study can help understand the complexity and dynamic nature of land use system.It has guiding significance on drawing up general land use planning,and gives advice to realize the land sustainable utilization.
