| Abstract: | Through investigation on the small lakes in the Basin of Lixia River in Jiangsu, the difference in temperature between water areas and their environments was analyzed. The denaturation and thermal transfer of air current over the water areas, the thermal efficiency of water and its influence on the near farmlands were dicussed. Besides, several models are established for estimating the extent and scope of thermal efficiency rising from water body with different scales. |
