Spatio-temporal variations and influencing factors of water yield in the Thousand-Island Lake basin in the past 30 years
【Objective】The Thousand-Island Lake basin is an important water conservation and ecological barrier area in the Yangtze River Delta. Thus, the study of water supply services is of great significance to ecological protection and high-quality sustainable development of the social economy. 【Method】The water yield of the Thousand-Island Lake basin was quantified over a six-year period: 1995, 2000, 2005, 2010, 2015 and 2019 based on the InVEST model, and water yield spatio-temporal variations and influencing factors were explored using the scenario and geodetector analyses.【Result】From 1995 to 2019, water yield inter-annual variations in the Thousand-Island Lake basin was consistent with precipitation trends; that is the water yield decreased significantly from 1995 to 2005, increased significantly from 2005 to 2015, and showed a subsequent marginal decrease from 2015 to 2019. Spatial distribution patterns showed little variation over the study period; however, patterns were high in the west of the basin and low in the basin’s eastern lake. The average water yield of buildings was higher than that of other land use types, followed by grasslands and woodland; water bodies had the lowest average water yield. Precipitation had a stronger effect on water yield than that of land use changes, which was significant. Actual evapotranspiration was the main driving factor of water spatial patterns, followed by land use types. The interaction between actual evapotranspiration and rainfall was the most significant than others. 【Conclusion】The water yield is the result of a combination of factors including climate and land use types. For the future ecological construction and environmental protection, the impact of terrain, climate, and human activities on water yield services must be considered and comprehensively studied.
