Abstract
There is a correlation between evapo-transpiration, soil water, and vegetation cover. Evapo-transpiration was measured in the three different cover types, soil, Sedum, and Zoysia. Evapo-transpiration was increased with less than 0.3 g cm-3 of soil water. The lower temperature of vegetation covering and soil surface caused by increasing of evapo-transpiration. However, temperature decreasing did not depend on the plant species, such as Sedum, and Zoysia, and soil type. The light spectrum was related to the different amounts of soil water and it was increased in near infra-red range by increasing of soil water.
