| Abstract: |
| 【Objective】The plant resources and application status of wet ponds in Hangzhou were investigated and
their suitability were evaluated, and suggestions for improving the application of plants in wet ponds in Hangzhou were put
forward to provide references for the construction of wet ponds and sponge cities. 【Method】The plant resources of 8 wet
ponds in Hangzhou were investigated on the spot and an evaluation system of wet pond plant suitability was constructed
from three aspects: growth suitability, aesthetic suitability and rainwater function suitability. The grade classification
was determined based on the comprehensive evaluation score. 【Result】There are 71 families, 129 genera, and 148
species of commonly used plants in the wet ponds of Hangzhou. Among them, there are many species of Rosaceae,
Gramineae, and Compositae. The repetition rate of plant applications is high, mainly for foliage and flower viewing, the ratio of evergreen species to deciduous tree species is 1 ︰ 2. Plant suitability evaluation results show that there are 2 plots
with grade Ⅰ (excellent), 5 with grade Ⅱ (good), and 1 with grade Ⅲ (normal),and the suitability of plants in Hangzhou wet
ponds is generally at a good level. Among them, Donghu Road Citizen Park has the highest comprehensive evaluation score
for wet pond plants, followed by Yangliu County West Park, and Guyuan Park has the lowest score. The three indicators of
maintenance needs, growth conditions, and rainstorm runoff reduction have the greatest impacts on plant selection in wet ponds.
【Conclusion】As an important terminal storage facility in the low-impact development system of sponge city, wet ponds have
an important influence on the performance of rainwater functions. The research results can provide a scientific reference for
the selection and application of wet pond plants in Hangzhou, and the research methods can also provide references for plant
selection and application in other low-impact development facilities. |
