Evapotranspiration and land surface temperature of typical urban green spaces in a semi-humid region: Implications for green management

Ecological deterioration and water scarcity motivate people to seek a balance between ecological reserves consumption in cities located Semi-humid regions. This study is designed develop method for evaluating cooling water-saving characteristics of green space structures. Land surface temperature ( T S ), vegetation quantity VQ ) evapotranspiration ET typical structures 50 plots with an average area 10,000 m 2 were studied. Parameters obtained based on data from three temporal remote sensing images; the energy algorithm land SEBAL model, single-channel algorithm, normalized difference index NDVI utilized calculation. The relationships , explored using regression analysis. A comprehensive EWI was proposed evaluate abilities different Based assessment results, species classified into three: good ≥ 0.795), common (0.795 > 0.419), weak < 0.419). 17 or compositions summarized as: 1) mix arbor, shrub, herb, 2) complete cover by shrub.
