Abstract

This paper presents an integrated evaluation model based on emergy analysis and fuzzy logic and using the geographic information system (GIS) to evaluate the health of agricultural land. An evaluation system is developed, which includes quality, productivity and the soil environment. A major grain-producing region in the North China Plain, namely Luancheng County, was selected for the case study. Field survey, household inquiry, sampling, and experimental analysis were conducted in the study area. Based on a composite index, the agricultural land was divided into 4 classes, namely in perfect health, in normal health, in sub-health, and in poor health.
