Research response of land surface water and heat flux to land use land cover changes in Laizhou Bay

Under the influence of the global change and human activity, the land use/land cover change (LUCC) is remarkable. The evapotranspiration is one of the key taches of the water cycle. And it's the component of both water balance and energy balance, which embodiments the balance of the substance, energy and the information system. The evapotranspiration is closely related to the land use and land cover change. In this paper, we first gives the dynamic characteristics of the land use and land cover change; and then, the distribution of the land surface water and heat flux and evapotranspiration, by means of the SEBAL equation, based on the radiation balance equation and energy balance equation; and finally, based on the tempo-spatial characteristics of evapotranspiration, we discusses the influence Of land use/cover change to the land surface evapotranspiration from two aspects: land use/land cover type and fresh/salt water
