Spatial and temporal evolution characteristics of the water conservation function and its driving factors in regional lake wetlands—Two types of homogeneous lakes as examples

Water conservation is the core wetland ecological function. The pattern of water conservation in geography often exhibits local spatial heterogeneity. In this paper, the Dongting Lake (DT) and Poyang Lake (PY) wetlands were taken as research objects, and the water yield (WY) module of the Integrated...
