  drought climate
Along the Yangtze River valley in central eastern China and Southwest China, interdecadal high temperature occurred from 1920s to 1940s and in 1990s, but the drought climate mainly appeared from 1920s to early 1940s.
      


An Australian cultivar of two-rowed barley (Hordeum distichon) has been grown at 19 different localities in Liaoning province for studying some agronomic and economic characters for two years. The results of this experiment suggest that the Australian barley has shorter growing period. The growing period from seedling emergence to mature was 77.7±7 and 79.3±2.7 days in 1981 and 1982 respectively. When it was sown in time, it would be harvested at late June. Its average 1000 kernel weight, within two years was...

An Australian cultivar of two-rowed barley (Hordeum distichon) has been grown at 19 different localities in Liaoning province for studying some agronomic and economic characters for two years. The results of this experiment suggest that the Australian barley has shorter growing period. The growing period from seedling emergence to mature was 77.7±7 and 79.3±2.7 days in 1981 and 1982 respectively. When it was sown in time, it would be harvested at late June. Its average 1000 kernel weight, within two years was 49.7±4.8g and 47.7±4.4g respectively. It was approximately 5.7g and 3.7g more than its original samples. The yields were 421.1 carries per mu in 1981, and 485.4 catties per mu in 1982. This Australian barley about 70—80 cm in height, with strong straw, resists to lodging and powdery mildew or rust as well. The nitrogen content in kernels of this cultivar was higher than original seed sample probably due to the drought-climate in local areas in these two years.

1981~1982年,在辽宁省内19个点进行了澳大利亚二棱大麦试种试验,结果表明,该大麦:(1) 生育期较短,从出苗到成熟,两年分别为77.7±7天和79.3±2.7天。如正常时期播种,一般6月下旬都能成熟:(2) 千粒重较高,两年分别为49.7±4.8克和47.7±4.4克,比原来种子提高5.7克、3.7克;(3) 产量较高,1981年平均亩产为424.1斤,1982年为485.4斤;(4) 该大麦一般高度为70~80厘米,茎秆较坚韧较抗倒伏;(5) 抗病性强,除少数试验点感轻度白粉病或轻度锈病外,其他各试点均无病情发生。但该大麦籽粒含氮量比原引进种子为高,可能与这两年当地天气干旱有关。

The variation of vegatation cover in a large range can change the physical properties on the surface, and influence evaporation from the surface into the atmosphere, because evaporation averaged for a long range on the whole globe should be equal to the corresponding precipitation, thus, it is possible that the variation of vegatation cover has some effects on the formation of precipitation in a certain region.In order to study the effects of the variation of vegatation cover on precipitation in a certain region...

The variation of vegatation cover in a large range can change the physical properties on the surface, and influence evaporation from the surface into the atmosphere, because evaporation averaged for a long range on the whole globe should be equal to the corresponding precipitation, thus, it is possible that the variation of vegatation cover has some effects on the formation of precipitation in a certain region.In order to study the effects of the variation of vegatation cover on precipitation in a certain region and drought climate, by the improved lorenz's low-order moist spectral model, six numerical experiments whose integrational times are longer than seventy model days are designed and performed. The physical processes introduced into the model are solar radiation absorbed by the surface, exchange of sensible heat, release of latent heat, hydrological cycle, convective adjustment, frictional dissipations, land surface heat budget, orographic effects, and differences between sea and land. The experimental re-sults show the increasing of the vegatation cover may increase the model precipitations, and shorten the durations in which the day's model precipitation is less than 1.0mm. It seems that the increasing of the degree of the vegetation cover contributes to an improvement of drought climate to a certain extent.

本文用改进了的Lorenz低谱湿模式,设计与实施了六个时间积分大于七十天的数值试验。模式包含的物理过程有:太阳幅射的地面吸收,感热输送,潜热释放,水份循环,对流调整,摩擦耗散作用,地形作用,陆面热量平衡和海陆差异。试验结果表明,大范围植被覆盖度的增加,使模式降水量增多,连续无降水日数缩短。似乎说明:植被覆盖度的增加可使干旱气候得到一定程度的改善。
