australia's biggest river system is shared by four states and feeds two-thirds of the country's irrigated farmland.

澳大利亚最庞大的水系遍布四个州，哺育着这个国家三分之二的农田。

on the other hand, the non-irrigated farmland, forestland and grassland degrade more seriously among all types of landscape utilization.

就不同土地景观类型而言，旱地、林地、草地生态系统退化较严重。

the pattern development and utilization of cultivated land is "half irrigated land, half no irrigated farmland" .

耕地利用格局大致为“水旱各半”，耕地兼有水田旱地，且水田稍多于旱地。
