Abstract:
Harbin Jinhewan Wetland Botanical Garden has the characteristics of unstable floodplain，and the growth of woody plants in different elevation is different.In this study，the whole garden was divided into three regions，and the 20 m × 20 m quadrats were selected as the investigation units.The plant species and growth status were collected，and the differences of plant species and spatial structure between 2011 and 2016 were compared.Then the suitable species of woody plants under different elevation in wetland were studied.The results showed that there were 29 species of woody plants in the park in 2016，belonging to 11 families，of which 16 species of trees and 13 species of shrubs.Under water habitat (elevation 115.17-116.00 m)，only Salix saposhnikovii and Salix matasudana，which were growing well.In the amphibious environment(elevation 116.00-119.49 m),except for Salicaceaeother plants grew in worse condition，compared with completion of plans in 2011，the species disappeared at a rate as high as 52.4%，the order of the survival rate of woody plants：Salix saposhnikovii（88.7%）> Salix matasudana(80.3%)>P.alba×P.berolinensis(78.5%)> Ulmus pumila(76.3%)>Betula platyphylla(72.8%)，all of them had good ability to adapt to the local environment under the elevation level.Even in flooded amphibious region(elevation 119.49-125.68 m)，the order of the survival rate of woody plants：Salix matasudana(97.6%)>P.alba×P.berolinensis(93.5%)> Ulmus pumila(90.7%)>Juglans mandshurica(89.6%)>Prunus triloba(88.5%)，all of them had good ability to adapt to the local environment under the elevation level.
