Ecological security evaluation and optimization system for microscale remediation of abandoned terrestrial field

Aiming to the technical needs in ecological restoration of the abandoned terrestrial fields, a practical evaluation and optimization system was suggested from the perspective of ecological security. The system mainly included site investigation, classification of contamination, establishment of resistance factor and model analysis, ecological security evaluation, as well as comparison and optimization of remediation strategies. Besides, a specific case was presented to apply this ecological security evaluation and optimization system at a typical contaminated site. This study provided a scientific and quantitative method for the strategy determination of microscale ecological remediation in abandoned terrestrial field.
