Off the Fukien coast near Amoy, Kinmen and such neighboring islands as Little Kinmen are only slightly more than 150 square kilometers in area. With strong winds and poor soil, only tough crops that don't need much water, such as sweet potatoes and peanuts, can grow there. It is a far from ideal environment for development.
與福建省廈門隔海相對的金門島連同小金門等小島，只有一百五十多平方公里大，風大、土壤貧瘠，只能種植耐旱雜糧如蕃薯、花生等，並非理想的發展環境。
