Survey on Theory and Driving Factors of Regime Shifts on Lake Ecosystems
摘要
Abstract
The lake ecosystem can undergo regime shifts triggered by long-term human threats and short-term strong disturbance. Before and after regime shifts, the ecosystem structure and key processes will change dramatically. For scientific management and decision making on lakes, it is therefore essential to reveal the mechanism and explore the driving factors of regime shifts. We concluded and discussed the concept and driving factors of regime shifts. Changing dramatically and difficult to forecast, ecosystem structure and key processes change, alternative stable state are main connotations of the concept of regime shifts. The characteristics of regime shifts include non-linear, alternative stable state, multiple thresholds, and hysteresis during restoration. There are external and internal factors in driving shifts between alternative states. The external driving factors include external nutrient loadings, climate change, storm, and water level. The influence of external nutrient loadings and climate change on lake ecosystem are long-term and accumulative. They can weaken the ecological resilience of lake to trigger regime shifts. Storm and water level are short-term factors and can trigger regime shifts shortly. The internal driving factors include fish, macrophyte. Fish can impose influence on macrophyte, lake sediment and zooplankton to trigger regime shifts. There is not only positive feedback effect of macrophyte on clear state of lake, also under certain conditions there is negative feedback effect. Some potential research focus was proposed based on the intensive literature review, including: (a) integrated influence of environmental and biological factors on macrophyte, (b) dominated states and key processes controlling the state based on large scale lake survey.关键词
