该文在MAPGIS技术支持下,以郑州市为例,依据“活动—性质—功能”的土壤功能分析框架,构建了土壤的生产功能、缓冲与过滤功能评价指标体系,并采用了层析分析法与指数和法对其进行评价,实现了土壤功能从定性到定量的评价,评价结果显示郑州市土壤的生产功能大体处于中等水平,但有进一步恶化的趋势,土壤缓冲与过滤能力较强,同时将其分别与农用地自然等分等成果、以绿色蔬菜产地土壤环境质量为标准的土壤环境质量评价成果进行比较分析,结果分布趋势较为一致,真实的反映了郑州市的实际情况。可为农业生产发展规划、城市建设发展和相关管理部门提供参考与决策依据。
With the support of MAPGIS technology and taking the city of Zhengzhou as an example, this paper constructs the evaluation index system of soil productive function, buffer and filtration function according to the soil function analysis framework of “activity - property - function” Analysis method and index and method to evaluate the soil function from qualitative to quantitative evaluation results show that the production of soil in Zhengzhou City, generally at a moderate level of production, but there is a further deterioration of the soil buffer and filtration ability At the same time, the results of soil environmental quality assessment were compared with the results of natural equal grading of agricultural land and the soil environmental quality of green vegetable producing area. The distribution trend of the results was consistent and truly reflected the actual situation of Zhengzhou City. For agricultural production development planning, urban construction and development and related management departments to provide a reference and decision-making basis.
