In this paper, the evapotranspiration and supplementary water requirement of paddy fields for different cultivating periods in China are estimated from heat and water balance climatological methods. The results may be summarized as follows: (1) The net radiation (R_0), evapotranspiration (E) and radiative dry index (R_0/L_r) of paddy fields for different cultivating periods in China are shown below: (2) The critical radiative dry index (R_0/L_r)_c needless of irrigation rapidly decreases with the increasing...

In this paper, the evapotranspiration and supplementary water requirement of paddy fields for different cultivating periods in China are estimated from heat and water balance climatological methods. The results may be summarized as follows: (1) The net radiation (R_0), evapotranspiration (E) and radiative dry index (R_0/L_r) of paddy fields for different cultivating periods in China are shown below: (2) The critical radiative dry index (R_0/L_r)_c needless of irrigation rapidly decreases with the increasing of percolation (P), and the slope of the correlative curve between (R_0/L_r)_c and P gradully decreases with the increasing of R_0. In present condition of rainfall ultilazation, the irrigation is necessary at any place and in every cultivating period according to (R_0/L_r)_c of the paddy fields during the cultivating period. (3) The supplementary water requirment (M) of paddy fields during the cultivating period increases with increasing of P and R_0/L_r, but it increases more rapidly in case of R_0/L_r below 1.0 than that above 1.0. (4) The calculation shows that the ratio of the area of catchment to the area of paddy field (A_(?)/A_(?)) also rapidly increases with R_0/L_r and P.

本文根据热量平衡与水分平称衡的气候学方法估算了我国各种造别水稻田的蒸散量与灌溉量。结果可总结如下:(l)我国各种造别水稻田的辐射平衡(R。/(L_r)蒸散量(E)和千澡度(R。/(L_r)如下表一所示:表一 (2)不需灌溉的临界干燥度(R。/(L_r)。随渗透量(尸)的增大而迅速减小,但(R。/(L_r)和p的相关曲线的陡度则随R。的增大而逐渐减小。根据水稻本田生长期的(R。/(L_r)。判断,在目前的雨量利用情况下,任何地点、任何造别的水稻田灌溉都是必需的。 (3)水猫本田生长期的灌溉量(M)随P和(R。/(L_r)护而增大,但这种增大在R。ILr小于1.0的范围内比在(R。/(L_r)大于1.0的范围内要快。 (4)计算表明,集水域而积与水稻田面积的比值(Ac/A,)同样随(R。/(L_r)犷和尸而迅速增大。

Based on field experimental results and systematic ecology, a coupling model is designed to simulate the temperature of the canopy water layer of a rice field. With different input into the model investigation is made of cold irrigation effect on the crop population structures and irrigative schemes, thus providing theoretical basis for the management of such rice growth.

在田间试验基础上,从系统生态学的观点出发,构建了水稻田冠层-水层温度场耦合模型。通过对模型的不同输入,模拟了不同天气条件,不同水稻群体结构以及不同灌溉方案下的冷灌效应,对低温敏水稻冷繁技术的生产实施具有指导意义。

The data obtained by the recruited observational period of HUBEX over rice field area at Shouxian site from June to July, 1999 are used to investigate the bulk transfer coefficients CD, CH and CE. Although the range of stability is relatively narrow over rice field area, the bulk transfer coefficients are mainly affected by the stability z / L, observational height z and the roughness length z0.

利用1999年夏季淮河流域能量和水循环试验(HUBEX)补充加强观测期间寿县观测站探测资料,计算分析了水稻田下垫表面上的整体输送系数CD、CH;和CE,并与能量平衡结果进行了对比研究。结果表明,尽管水稻田下垫面上的稳定度集中在一狭小区间内,但整体输送系数CD、CH和CE仍取决于稳定度参数z/L、观测高度z和地表粗糙长度z0。
