| 英文摘要 | In order to study energy and water cycles in the Huaihe River Basin, micrometeorological measurements were carried out in Shouxian County, Anhui Province, during HUBEX/IOP (May to August 1998 and June to July 1999). The employed techniques included Bowen Ratio-Energy Balance (BREB) and Eddy Covariance (EC) methods. In this paper, the basic characteristics of the energy balance components in the district are analyzed. Furthermore, the results axe compared with those from other regions of China. The main results axe as follows: (1) There was a consistency between the available energy (R-n - G) and the sum of sensible (H) and latent (E) heat fluxes measured by the EC method (H+E)(ec), but E-br was slightly larger (about 10%) than E-ec; (2) Most of the net radiation (R-n) was used to evaporate water from the surface. During HUBEX/IOP in 1998 and 1999, the mean daily amounts of R. were 13.89 Mj m(-2) d(-1) and 11.83 Mj m(-2) d(-1), and the mean Bowen Ratios (beta) were 0.14 (over ruderal) and 0.06 (over paddy) respectively; (3) The diurnal variation characteristic of beta was larger and unsteady at sunrise and sunset, and smaller and steady during the rest of the daytime. Local advection appeared in the afternoon over paddy areas in 1999; (4) In comparison with the results from other regions of China, the mean beta was the lowest (0.06) over paddy areas in the Huaihe River Basin and the highest (0.57) during June-August 1998 in Inner Mongolia grassland. The Bowen Ratio, beta is mainly related to the soil humidity. |
