基于GIS的小区域土地利用潜力评价

Land use potential evaluation of small region based on GIS

根据已有土地评价系统和评价表,制定出符合项目区实际情况的评价系统及评价单位和评价表,对各个评价指标进行权重分析,运用层次分析法和合适的数学模型对其进行计算,从而得出量化的权重分级表,对土地利用潜力进行评价.

According to the existing land evaluation system and the evaluation form,the evaluation system,evaluation unit and evaluation form coincident with the actual situation in the project area are established,and then the weight of each indicator is analyzed.Using the Analytic Hierarchy Process and appropriate mathematical model,the quantitative weight classification table is arrived,and then the land use capacity is evaluated.
