| 中文摘要 | 据1987年5—10月在北京西山李子峪沟观测所得的微气候资料,运用波文比-能量平衡法,研究了坡地的辐射状况及能量平衡的各分量变化规律。分析结果表明,与阴坡相比,阳坡总辐射强度、净辐射量均较大;在雨季(6—8月),阴阳坡蒸发散量均为3.4—4.4毫米/日;潜热通量占净辐射量比例:阳坡约62％,阴坡约67％;植被层下土壤热交换量占净辐射量比例:阳坡约16％,阴坡约12％。 |
| 英文摘要 | According to the climatical data, observed in Lizhiyu Valley of the West Mountain of Beijing (116°28′E,39°54′N) during May-October of 1987, the investigations of the slope radiant conditions and all components of slope energy balance are analysed by theBowen ratio-energy balance method. Its results are as follows:1.By comparison with the shady slope, the total radiation and net radiation of the sunny slope are generally greater.2.The average albedo of the denudated soil. the sunny slope is 20%, the shady slope 18 %; the average albedo of vegetation: the sunny slope 19%, the shady slope 20%.3.The evapotranspiration of the shady and sunny slopes in rainy season (from June to August) vatied between 3. 4-4. 4mm/d; that of the sunny slope on September -was still over 2.0mm/d, but that of the shady slope slightly smaller.4.The sum of the latent and evident heat flux of the sunny slope are about 84 % of slope net radiation, that of the shady slope about 88%; while the latent heat flux of the sunny slope are about 62% of slope net radiation, that of the shady slope about 67%.5.The proportion of the soil heat flux under vegetation to slope net radiation: the sunny slope about 16%, the shady slope about 12% , are much more than that of the storing heat of the vegetation to slope net radiation(<1%). |
