lease oxygen, improving urban air quality. Street green spaces and community gardens are
distributed across various urban areas, enhancing the connectivity of urban green spaces and
improving ecosystem service functions. Street green spaces provide pedestrians with shaded
resting areas while beautifying the urban environment; community gardens encourage resi-
dent participation in planting activities, raise environmental awareness, and to some extent
increase urban green coverage.
Wetlands, as a crucial component of urban ecosystems, receive significant attention
from cities. Cities strictly protect existing wetlands by delineating wetland protection red
lines, clarifying conservation boundaries, and prohibiting any illegal occupation or destruc-
tion by organizations or individuals. Concurrently, active wetland restoration projects are
implemented. These include restoring wetland vegetation through planting locally adapted
aquatic species to rebuild ecosystem biodiversity; improving water quality by removing pol-
lutants through sewage treatment facilities and ecological purification technologies, thereby
enhancing wetland ecosystem functions. Wetlands possess powerfulcarbon sequestration
capacities, their vegetation and soil can absorb and store large amounts of carbon dioxide,
playing a significant role in mitigating climate change. During extreme weather events such
as heavy rainstorms, wetlands can function as flood regulation systems. Acting like natural
reservoirs, wetlands can store substantial rainwater during floods to reduce urban impacts,
while gradually releasing stored water during droughts to replenish urban water resources.
By constructing ecological corridors, cities connect green spaces, wetlands and other eco-
systems. These corridors - whether rivers, forest belts or green pathways - provide migration
routes for species, facilitatespecies exchange between different ecosystems, enhance eco-
system stability and resilience to disturbances, thereby further strengthening urban climate
change adaptation capabilities.
V. Public Participation Mechanisms for Climate Change Response at
City Level

Urban efforts to address climate change cannot be achieved without extensive public
participation. Establishing effective public engagement mechanisms and platforms is crucial
for promoting the smooth implementation of urban climate actions.
Community initiatives play a fundamental role in urban climate responses. Cities ac-
tively encourage community organizations to carry out various energy conservation and
emission reduction activities. In some communities, environmental volunteer groups have
been established. These volunteers regularly organize residents for waste sorting promo-
tional activities, educating them about the knowledge and importance of waste classification
through lectures and on-site demonstrations, thereby enhancing residents’ awareness and
participation in waste sorting. Energy conservation knowledge lectures are conducted, in-
viting experts to teach residents methods and techniques for household energy saving, such
as rational use of electrical appliances and adjusting air conditioning temperatures, guiding
