Regional assessment of human-caused ecological risk in the Poyang Lake Eco-economic Zone using production-living-ecology analysis.

ABSTRACT: In this study, based on the regional land-use risk space division (regional ecological risk source/receptor space identification) using production-living-ecology analysis, three spatial function indexes, i.e., production, living, and ecology function indexes, were proposed for regional ecological risk assessment (RERA) with respect to human disturbance. The first two indexes can be regarded as regional ecological risk source indexes, whereas the final index can be regarded as a regional ecological risk receptor index. Using an artificial assignment method based on the land-use types and Defense Meteorological Program Operational Line-Scan System (DMSP/OLS) nighttime light intensity data, these three spatial function indexes were effectively manifested. By incorporating these indexes with e
