| 摘 要： | 城乡结合部是位于中心城市区与外围典型农业区之间，具有城市与乡村双重特征的过渡带。土壤质量是土壤在生态系统边界范围内维持作物生产能力，保持环境质量及促进动物健康的能力。以开封市为例，在实地采样调查的基础上选取一定的参数，修改内梅罗公式，对其城乡结合部土壤的整体质量及不同土地利用方式下的质量进行评价，于1982年土壤普查结果作对比，探讨土壤质量的动态变化；从土地利用的角度分析了因其土壤质量变化的原因，提出维持和提高开封市城乡结合部土壤质量的措施。 |
| 关 键 词： | 城乡结合部 土壤质量 动态变化 开封市 |

| Abstract: | Situated in between the central city and surrounding typical agricultural region, the area joining town and country is a transitional belt of land use, society and population which has dual features of rural and urban district. Soil quality refers to the capacities of soil for sustainable crop productivity, environmental quality and health of biota in the ecosystem. Based on the practical sampling and research, this article selects certain parameters including pH, organism, total nitrogen, quick\|acting phosphorus, quick-acting kalium and cation substitution to modify Nemoro Fomular and assess the overall soil quality and quality of soils under different land use patterns. The results indicated that vegetable land is the best and dry land is the worst. The paper probes into dynamics of soil quality based on the comparisons of present conditions with that in the 1982, which revealed that soil quality decreased from 1982 to 1998 and total nitrogen and quick\|acting phosphorus are accountable for the soil quality changes. It also puts forward measures maintaining and improving soil quality in the area joining town and country of Kaifeng. |
