The carbon sequestration capacity of trees plays a crucial role in determining the carbon sink potential in urban green spaces. To investigate the variations in carbon sequestration capacity among tree species and their impact factors, we selected four common tree species (Cinnamomum camphora, Metasequoia glyptostroboides, Ginkgo biloba, Cedrus deo...

Outdoor heat stress possesses significant health risks, contributing to thousands of premature deaths each summer. Urban greening has been widely recognized as a potential solution to mitigate this heat threat. However, the optimal way to maximize cooling effects from urban forest—specifically through the influences of plant leaf traits and canopy...

Urban forests can mitigate urban heat effectively during hot summer days. Their cooling effects are largely determined by the plant canopy structure, which can be classified into three features: canopy density and horizontal and vertical canopy structures. This study aimed to identify the contribution of these canopy structural features to cooling...

As the components having the highest biological activity and fastest turnover rate in the plant root system, fineroots (≤2mm) are very sensitive to global climate change and significantly affect the carbon balance and nutrient cycling inthe belowground part of the terrestrial ecosystem. Coastal wetlands are among the ecosystems with significant car...

Remote Sensing (RS) techniques are increasingly used in urban tree inventory measurements for their improved accuracy and promptness over the conventional methods. The focus of this study is to evaluate the application of iPad Pro 2020 and its LiDAR sensor for urban trees reconstruction and Diameter at Breast Height (DBH) measurements. Altogether,...

SfM can produce image-based point clouds with high accuracy and quality only by consumer cameras. In this paper, we evaluated the urban trees reconstruction and Diameter at Breast Height(DBH) measurements by SfM based on a circular urban forest plot(radius = 6 m) to verify the feasibility for urban forest inventory. Furthermore, hand-held laser sca...

In this study, ground−level air pollutants (i.e., particulate matter (PM), NO2, and CO) were monitored at two transects of an urban−road−green−belt of Shanghai for one month during the summer season. Four monitoring sites at 100m intervals were set along each transect from the road to the inside. The air pollution was evaluated for each site based...

The patent designed a fully automatic control irrigation device for the integration of water and fertilizer for vertical greening. The patent can solve the problems of water resource waste, single appearance, can't splicing and high technical requirements caused by the existing model. At the same time, the device is quantitative, uniform, accurate,...
