基于GIS的东营市土地适宜性评价研究

Dongying City Land Suitability Evaluation Research Based on GIS Technology

依据土地适宜性评价原则,以山东省东营市土地适宜性评价为例,探讨了运用GIS技术对用地的自然、社会属性进行综合评价的数量化方法,结合当地实际情况,选取了土壤类型、地下水位、全氮、全磷、土壤盐分五个评价因子,各因子的适宜度的确定和各单元因素适宜性的评价,对评价结果进行了分析,提出了土地改良应用的合理化建议。将GIS引入到土地适宜性的空间评价中评价方法更科学,使评价结果能更好地为土地利用和规划服务。

In this paper, Based on the land suitability evaluation principles, in Shandong province Dongying city land suitability as- sessment, discusses the quantitative method for comprehensive evaluation of natural, social attribute by using GIS technology, com- bined with the local actual situation, selects the soil type, the underground water level, total nitrogen, total phosphorus, soil salinity five evaluation the determination of the degree of each factor, and unit factors suitability evaluation for each factor, the results of evalu- ation are analyzed, and puts forward some rational suggestions improved land application. GIS will be introduced to the land suitability evaluation of land resources in the space of more scientific evaluation method, the evaluation results can be better for the land use and planning services.
