川南降水的时空分布及农业意义

The Precipitation's Distribution in Space and Time and Its Agricultural Meaning in Southern Sichuan

川南位于四川省南部,包括自贡市、宜宾地区及泸州市,面积28461平方公里。川南拥有肥沃的土壤、丰富的热量,有利于耕作业的发展;但地貌特别是水分条件构成了耕作业发展的主要限制因子。本文即试图对川南降水的特征进行探讨,为农业发展提供参考。

It's indicated that the precipitation in southern Sichuan not only distributes unequally in space and time but also changes un-simultaneouslly with Crop's water-requirement in Seazon distribution for analysing the precipitation and Crop's wate r - requirement.So it's necessary to regulate the volume of water in Seazon and region,being solved through engineering and changing cultivation-system.
