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。
Based on the principle of land ecological health evaluation, the index of land fertility was selected to evaluate the land health, which provided the basis for land use regulation. Taking the three counties in northeastern Henan Province as an example, spatial distribution pattern of land fertility was obtained by investigating the land quality in the study area, and based on this, the comprehensive index of land fertility and health was calculated. The comprehensive analysis of the factors influencing land fertility showed that the comprehensive indexes of land fertility and health in the study area were below average. The index of land health and resilience in the study area and the corresponding index system can reasonably reflect the adaptability of land health, land use and economic layout to the bearing capacity of resources and environment, and provide a theoretical basis for sustainable development of the region.
