根据湖南省1956年底的统计,在全省丘陵地区的3,408万亩灌溉面积中,依靠山塘灌溉的为1,826万亩,占53.5%。这说明在南方丘陵地区,主要的灌溉水源是山塘。但是过去我们对于这个重要的水源所作的工作很少。1957年5～10月我们在湖南省醴陵县新联农业社选择了一口独立的山塘——清水塘进行了水量平衡各项因素的观测,这里仅将其初步成果和工作中的几点体会介绍如下:希望大家批评和指正。 According to the statistics of Hunan Province at the end of 1956, of the 34.48 million mu of irrigated area in the hilly areas of the province, 18.26 million mu (53.5%) rely on mountain ponds for irrigation. This shows that in the southern hilly region, the main source of irrigation water is the ponds. But in the past we have done very little to this important source of water. From May to October 1957, we selected an independent pond-Qingshuitang pond in Liling County, Hunan Province, to observe the various factors of water balance. Here, we will only discuss the preliminary results and some points in our work Described as follows: I hope everyone criticism and correction.
