Abstract

China has developed more than 20 water pollution control plans for river basins RBWPs since 1996 However the implementation has generally lagged This paper proposes a threestep postevaluation methodology to analyze the implementation result of a RBWP and its influential factors First a multiattribute evaluation method based on an index system is established to score the enforcement results of a RBWP Indicators measure how well a RBWP has achieved its objectives which include water quality compliance pollution load control project construction financial inputs and related management requirements Second an interpretive structural model is used to detect the significant factors that affect RBWP implementation This model can effectively analyze the causeeffect chain and hierarchical relationship among variables Five groups of factors were identified namely plan preparation water resource endowment policy institution and management Both qualitative and quantitative methods are employed in the third step to evaluate the extent to which these factors have influenced the execution result of a RBWP including prepost contrast scenario analysis and correlation analysis This research then postevaluated the implementation of the Huai River Basin water pollution control plans HRBWPs over a period of 10 years as a case study Results showed that the implementation of the HRBWPs was unsatisfactory during 2001–2005 although it improved during 2006–2010 The poor execution of these plans was partially caused by the underestimation of regional economic development in combination with ineffective industrial structure adjustment policies Therefore this case study demonstrates the feasibility and flexibility of the proposed postevaluation methodology
