In general, young plants in the establishment phase demonstrate sensitivity to changes environmental conditions, especially regarding water availability. The effects of seasonality biophysical processes on plant physiology can trigger differential responses, even within same region, making it necessary conduct studies that characterize physiological performance species at different spatial and temporal scales, possible understand their needs growth limits under stress conditions.

Cities play a critical role in anthropogenic CO2 emissions, which exacerbate climate change and impact urban populations. Urban green infrastructure, such as trees, provides essential ecosystem services, including reducing atmospheric levels. However, there is significant knowledge gap regarding the of trees on semiarid, polluted cities like Tehran, capital largest metropolis Middle East. This study assesses carbon sequestration storage potential Tehran’s infrastructure using i-Tree Eco model. A randomized cluster sampling method was employed, collecting data species composition, diameter at breast height (DBH), total tree height. The results indicate that sequester approximately 60,102 tons per year, equivalent to 220,393 CO2. net about 254,579 tons, 933,455 Parks spaces demonstrate highest rate hectare, followed by services land use. Prioritizing planting with high rates Cupressus arizonica (Arizona cypress) sempervirens L. var. horizontalis (Mediterranean could enhance efforts Tehran. These provide valuable insights into environmental different use types, may aid development effective policies management strategies semiarid areas other similar settings.

Carbon dioxide emissions, leading to global warming, have threatened human development. It is urgent control and slow down greenhouse gas emissions maintain ecologically sustainable The energy demand pollutant generated in the process of urban development are main reasons climate environmental change. Scientific planning for cities construction low-carbon models first work deal with issues. In view these problems, article takes Guangyuan City as an example city construction, through transforming city's industrial structure, strengthening science technology innovation, establishing improving system other methods implement specific city, build a clean, low- carbon new life mode, Make from 2015 reach exploitable hydropower installed capacity 65% 80% 2020. this paper, we propose series spatial layout strategies, which not only in-depth analysis key problems China's urbanization process, such consumption, etc., but also targeted solutions. By implementing can effectively meet challenges brought about by promote Chinese more direction.
