澳大利亚处于南半球,其南部和中国北部气候相同,而北部则和中国南部一样。离海岸线200公里处就很干燥,没有天然植被。例如莫雷河边的沙土地带,高温时达40℃,而年降雨量只300毫米,植被很象沙漠地带。这个地区所有的喷灌水源均来自莫雷河,要提水30～40米,并穿过山谷才能用于灌溉。国家用航空 Australia is in the southern hemisphere, with the same climate in the south and in northern China, while the north is the same in southern China. 200 km from the coastline is very dry, there is no natural vegetation.

All the irrigation water in this area comes from the river Morey, with 30 to 40 meters of water and irrigation through the valley. Country with aviation
