层次分析法在四川省通江县广纳镇土地评估中的应用

应用层次分析法对四川省巴中市通江县广纳镇地区的土地进行了质量评估。通过分析影响各评价指标的主要因子．建立各层次结构模型和质量指数数学模型，得出地球化学综合指数，评价了该地区土地的质量状况。在此基础上．对各指标进行优化选择，比较所选的不同指标对建立土地质量评估最终结果的影响差异，进行指标筛选的探索。评价结果显示．佛驹山村的土壤质量情况较好，高坑坝村的土壤质量较差。

Application of the analytic hierarchy process in the evaluation of land quality of Guangna Town, Tongjiang County, Sichuan, China

The analytic hierarchy process (AHP) was used to perform a quality evaluation of the land at Guangna Town, Tongjiang County, Bazhong City, Sichuan Province. Main factors which may influence various indices were analyzed and various hierarchy models and quality index mathematic models were constructed. Thus the geochemical comprehensive indices were obtained and used to evaluate land quality in the study area. On that basis, the authors selected suitable evaluation indices, compared the differences in influences of the various selected indices on the final results of land quality evaluation and explored the selection of the index sets. The evaluation results indicate that the land quality is better at Fojushan Village but worse at Gaokengba Village.
