摘　　要：基于土地生态健康评价原理,选取土地肥力指标对土地健康进行评价,为土地利用调控提供依据。以河南省东北部三县为例,通过对研究区域内土地质量进行调查,得到土地肥力空间分布格局,并以此为依据计算土地肥力健康综合指数。将影响土地肥力的因子指标进行综合分析,结果表明,研究区域土地肥力健康综合指数均在中等以下。研究区土地肥力健康综合指数和相应的指标体系能较为合理地反映土地健康、土地利用、经济布局与资源环境承载力相适应,能够为区域可持续发展提供理论基础。To discuss the idea of land nutrient evaluation under new circumstances,based on the principle of land ecological health assessment,which can provide references for the adjustment of regional land use,three counties are selected in northeast of Henan Province as example.The integrated soil fertility quality is determined according to the spatial combination of indices of soil nutrients,which are assessed in terms of the standard of state.The results indicate that the spatial distribution of soil fertility quality at the middle level.It is concluded that the land ecological assessment can clearly reflect the relationship between changes in land use and social economic development.It can further accelerate the compatibleness among land use,economic zoning,and carrying capacity of resources and environment,and also enhance the sustainable development ability.
