Abstract

Human have a long history of implementing hydrological regulations in lakes. With the rapid increase in global population since the mid-20s, the anthropogenic pressure on freshwater resources has intensified, which would result in abrupt change in lake ecosystems. A meta-analysis study had been cond...
