| 摘要: |
| 本文采用云南省20年(1951—1970)降水资料,计算出七个区域的年平均降水垂直递增率为23—79毫米/100米,并绘制1300米、1700米和2000米等高面年平均降水量分布图,初步揭示了稻作区水分状况的立体特征。用各地区代表站30年(1951—1980)降水资料,通过降水保证率、相对变率和湿润状况的计算,对粳稻、籼稻和双季稻栽培上限高度的水分资源进行初步分析,并提出正确的决策。 |

| Abstract: |
| This paper is based on the 20-year(1951-1970)precipitation data of Yunnan province.The vertical increasing rate(23-79mm/100m)of mean annual precipitation in seven areas were calculated,and the charts of the distribution of mean annual precipitation at the constant levels of 1300m,1700m,and 2000m were drawn.These charts initially brought to light the stereoscope feature of the water condition of rice planting areas.Based on the 30-year(1951-1980)precipitation data of selected stations sepresenting various ar... |
