Lake ecological security assessment based on SSWSSC framework from 2005 to 2013 in an interior lake basin, China

摘要: The increasingly serious ecological security issues of lake systems have aroused increasing political and academic attention. Based on research regarding domestically abroad, this study brings forth the concept security. A new selection-system-weight-standardization-standards-calculation framework for at watershed scale was proposed, it integrates several existing methods, including “driver-pressure-state-impact-response” framework, analytic hierarchy process fuzzy assessment model, to systematize ecology meet needs management. This systematic applied comprehensively assess an interior basin in China from 2005 2013, using year 2000 as a comparative reference. results illustrated that index (ESI) values 2013 were 0.58 “common” level 0.61 “good” level, respectively, area. From 2012, ESI stable, mostly between 0.4 0.6 with exception 2007 “poor” level. Then, result individual used reference we found response better than state nearly equal driving force close level; however, pressure impact relatively not ideal. These can be basis eco-environmental
