南方水稻面积波动与我国夏季降水分布的相关性分析

Analysis of Correlation between Fluctuation of Rice-planting Area and Allotment of Summer Rainfall in South China

对我国南方水稻主产区水稻面积的消长与我国各主要气象站点夏季降水量变化的相关性及其区域分布情况进行了分析。结果发现，水稻面积变化与我国各地夏季降水量的变化有一定的相关性，主要表现在6～8月江南地区降水量与南方水稻面积呈负相关，7、8月长江以北大部分地区降水量与南方水稻面积呈正相关。

In this paper, in south China, the correlations between fluctuation of rice - planting area in main rice - planting regions and changes of summer rainfall in the main weather stations were analyzed. The results showed that the rice - planting area influenced the rainfall to a certain extent. In January and February, a positive correlation exists between the rainfall precipitation in the north, north - east and south to Yangzi River in China and rice - planting area in the southern rice - planting regions; but in summer, a nega- tive correlation in the south China. From July to August, in the north Yangzi River and September most regions excluding the northwest the rainfall precipitation has negative correlation with the southern rice - planting area, but in December and January, a negative corre- lation in most of China.
