Abstract:
Wetland vegetation is one of the important indicators for evaluating the spatial structure, function and process of wetlands. In the light of the problems of few vegetation types, poor water quality, low landscape diversity and poor ornamental effect in Liuli River Wetland Park in Beijing, aiming at the realization of water purification, species conservation, ornamental and science popularization of the wetland, the main river channel was optimization and new wetland construction were studied. Based on current landuse status and restoration objectives of the study area, three functional areas of wetland restoration, i.e. water purification functional area, species conservation functional area and ornamental and science popularization functional area, as well as their overall layout were proposed. For different functional areas, the reconstruction schemes of wetland ecological elements were proposed from the aspects of base restoration and vegetation allocation. In the scheme, an area of 1.13 km
2 of wetland was optimized and constructed, and 28 vegetation communities were allocated. This scheme could improve the ornamental functions of the study area while taking into account the purification of water quality and species conservation function.
