一、斯里兰卡大约有三分之二的土地面积按气候划分干旱区,因为该地区一年只有三个月大雨,其余九个月连续干旱。由于存在对农业的有利条件.国家粮食生产的主要部分是以这个地区为基础的.农业灌溉用水主要由水库来提供,这些水库由来自中部丘陵常年不断的河流供水。然而,由于地形状况,自流灌溉只能适用于一部分这样的土地,而旱季高地的种植只能靠提灌地下水或从常年不断的河流提水灌溉。斯里兰卡农民过去为了提灌一直使用人力与畜力提水工具.然而.现在这些工具几乎完全为机灌所代替。这种情况已使该国整个农业
First, about two-thirds of Sri Lanka’s land area is divided by aridity because of the heavy rains in the area for only three months a year and the continuous drought for the remaining nine months.

In the past, Sri Lankan peasants used to use manpower and livestock to raise water, but these tools are now almost completely replaced by irrigation. This situation has given the country as a whole agriculture
