盆地中部是我省的老旱区。为有效地制伏干旱,我们对盆地中部干旱出现规律、形成原因以及防御措施进行了调查。现从农业气象角度探讨该区干旱的一些解决途径。一、加强蓄水保水,提高降水利用率 1、降水资源,有潜可挖:经计算,从沱、涪、嘉三江流域面积内流走的自然降水量,即达186.9亿方,折合降水量360毫米,占该区平均年降水量的36％。换言之,盆
The middle of the basin is the arid area in our province. In order to effectively control the drought, we investigated the law of the occurrence of the drought in the central part of the basin, its causes and the preventive measures. From the perspective of agricultural meteorology, we discussed some solutions to the drought in the area. First, to strengthen water and water conservation, improve precipitation utilization 1, precipitation resources, there is potential to dig: After calculation, from Tuo, Fu, Ji Sanjiang drainage area within the flow of natural precipitation, which reached 18.69 billion cubic meters, equivalent to precipitation 360 mm, accounting for 36% of the average annual precipitation in the area. In other words, pots
