摘  要:
以鲁西北地区县级空间数据库和属性数据库为基础,采用"机制法"对农业土地资源生产潜力模型进行了光、温、水、土、社会因子逐级订正。研究结果表明,"机制法"能够很好的反映鲁西北地区农业生产和农业土地资源分布的空间格局和区域差异,各级订正的有效系数进一步揭示了鲁西北地区各种资源因子对农业生产的限制程度。

摘  要:
By using spatial database of 1:50000 soil type map and attributes databases including meteorological data, soil properties data and statistical data on agriculture, effective coefficients for factors such as radiation, temperature, water, land resources and social factors were decided. Then, agricultural potential land productivities were computed by using relevant computing models of mechanism methodology and mapped based on geographic information system(GIS) in this paper. Results indicated that the mechanism methodology could reveal well the regional heterogeneousness of potential land productivity and spatial distribution of agricultural resources among different counties. Moreover, the results showed different limitations of radiation, temperature, water, land resources and social factors to agriculture production.
