Abstract

Abstract: Ecological risk assessment is a key measure of ecological environment management. To assess the ecological risk at regional scale is of practical significance in strengthening ecosystem management and regional ecological safety. This paper reviewed the concept, definition, main contents, and development process of regional ecological risk assessment, and discussed the key issues in related researches, e.g., region, scale, model, and uncertainty. In the meanwhile, the further research directions on regional ecological risk assessment were prospected.

Key words: Urease inhibitor, Nitrification inhibitor, NH₄⁺-N, NO₃^--N, NO₃^-leaching
