利用多种来源的不同专题空间数据,运用特尔菲法建立评价指标体系并确定各评价因子的权重值,以GRID(栅格)作为评价单元,在GIS支持下进行空间叠加分析,对张掖市土地生态适宜性进行了评价,实现了环境评价结果全空间区域的定量表达.对张掖市土地用途管制分区进行了划定,并提出环境友好型的土地生态适宜发展模式.研究表明:利用多源空间数据叠加分析的方法,可以比较综合地了解区域环境背景的整体特点及其差异,评价结果较为客观地反映了张掖市土地适宜性空间分布及其区域分异特点.

Taking Zhangye City as a case, this paper selected GRID as the evaluation unit, filtrated the index of evaluating applying Delphi method and determined the weight value in order to establish the grade standard of land eco-suitability. Then, a synthetic assessment of land eco-suitability in Zhangye was carried out by using multi-source spatial data and GIS spatial overlay method. Combined with suitability analysis, Zhangye City is divided into 7 regulation zones, and some environment-friendly land-use countermeasures and advices for environmental development were put forward. This study can provide scientific basis for regional land use planning, eco-environment protection and construction planning. Results indicated that the method of multi-source spatial data overlaying analysis can reveal the overall feature and difference of regional environmental background synthetically. Studying results reflected the spatial distribution and regional difference in Zhangye objectively.
