The temperature difference between an urban space and surrounding non-urban space is called the urban heat island effect （UHI）. Global terrestrial evapotranspiration （ET） can consume 1.4803x1023joules （J） of energy annually, which is about 21.74% of the total available solar energy at the top of atmosphere, whereas annual human energy use is 4.935× 1020 J, about 0.33% of annual ET energy consumption. Vegetation ET has great potential to reduce urban and global temperatures. Our literature review suggests that vegetation and urban agricultural ET can reduce urban temperatures by 0.5 to 4.0℃. Green roofs （including urban agriculture） and water bodies have also been shown to be effective ways of reducing urban temperatures. The cooling effects on the ambient temperature and the roof surface temperature can be 0.24-4.0℃ and 0.8-60.0℃, respectively. The temperature of a water body （including urban aquaculture） can be lower than the temperature of the surrounding built environment by between 2 and 6℃, and a water body with a 16 m2 surface area can cool up to 2 826 m3 of nearby space by 1℃. Based on these findings, it can be concluded that the increase of evapotranspiration in cities, derived from vegetation, urban agriculture, and water body, can effectively mitigate the effect of urban heat islands.

To reveal additional effects of aquatic macrophytes on biogeochemical properties of onshore lake phosphorus and to investigate the ecological response of reed communities to this phosphorus,sediments from the Meiliangwan onshore reed area of Lake Taihu were sampled by using a columnar sampler (D=8 cm) on September 18,October 17 and December 3,2003. The samples were compared with those from macrophyte-free areas. The collected samples were dried naturally at room temperature,ground and screened with a 100 mesh sieve. The HClO4-H2SO4 digesting and H2SO4-H2O2 heating digesting methods were used to analyze the total amount of phosphorus (TP) contained in sedi-ments of the reed area and in tissues of reed roots and stems. The result shows: 1) the level of TP,from both the reed area sediment and the reference samples,is highest during the vigorous growing stage and lowest during the slow growing stage. The difference between the two levels is statistically significant (p rhizome > stem. All are smaller in the level of phosphorous than that in rhizosphere sediments (0-2 cm).
