Ecological Planning and Design of Urban Green Space System of Sanya City

The construction of International Tourism Island has accelerated the development of Sanya City. The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as "One Belt & Three Bays, One Core & Six Towns, Two Axes & Three Wedges, Two Net Synchronous-construction" strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.

Urban avifauna distribution explained by road noise in an Eastern European city

In Eastern Europe,efforts are being made for road infrastructure development,as this area has not yet reached the level of that in the West.Road noise negatively affects birds,especially in urban habitats.Therefore,seven green spaces from an Eastern European city were monitored,which were selected according to the urbanization gradient and the hydrographic peculiarities of the area.The correlation between species richness and human population density,urban mobility,or road noise was verified.These three factors together explained over 99%of species richness distribution in habitats and during study periods.Road noise was the strongest predictor and the most negative influencer of bird species.These correlations were higher when we also considered the variability of species in habitats over time,instead of the total species richness of a habitat,as it expresses more accurately the impact of noise on the presence of species.The presence of species has decreased from one habitat to another along the urbanization gradient,from the edge of the city to the center,both in the case of terrestrial and aquatic green spaces.The most central park differed significantly from the other terrestrial green spaces in the city.At the same time,no significant differences were registered between the aquatic habitats or the rest of the terrestrial habitats.The ideal mitigation measure in this case would be that there are no roads in the immediate vicinity of green spaces.Still,if this is not possible(as in the case of all the existing green spaces in a city),we discuss/recommend placing noise barriers at the edge of green spaces or high-speed roads.
