Performance Evaluation of Watershed Environment Governance—A Case Study of Taihu Basin

The rapid development of urbanization and industrialization brings a series problems environment governance, several basins are facing huge pressure. This paper selects the Taihu basin in Yangtze River Delta China as study area, establishes DPSIR model to measure water governance performance region (Cj), analyzes causes changes five subsystems (the is recorded C1j,C2j,C3j,C4j,C5j), uses diagnostic identify barrier factors that restrict improvement Cj last 5 years. results show during period, C1j driving force subsystem generally tends increase maintains steady growth, which closely linked economic growth basin; C2j pressure increases with small fluctuation, pollution generation still needs attention; state subsystem, C3j shows large varies significantly cyclical manner, corresponding short maintenance time repeated treatment watershed; C4j impact an overall upward but slightly slower trend, it related fact industrial structure be improved; C5j response trend larger increase, multi-actor collaborative management has helped lot. main include key cross-sections’ quality compliance rate, rate function areas, consumption per 10,000 yuan added value, lake trophic status index. Based on study, article gives recommendations for watershed such controlling generation, optimising structure, using technological tools help sharing cost among multiple parties strengthening supervision findings make scientific environmental protection planning policies region. research can also provide experience other countries regions governance.
