摘　　要：本文通过最近三个时期的遥感分析表明 ,四湖地区乱占耕地现象比较严重 ,人地矛盾日趋恶化。该地区自然属性较为优越 ,但土地利用效益差 ,局部地区土地退化严重。必须采取相应有力措施 ,改善农业生态环境 ,提高土地质量。Remote sensing analysis of the last three periods was made in this paper. It shows that the phenomena of arbitrary occupation of cultivated land is very serious, and the contradiction between the man and land has steadily deteriorated. Though the natural condition of this area is favourable, the landuse benefit is poor, and the degeneration of land in some areas is serious. So it is imperative to take appropriate measures to improve the agricultural ecological environment and the quality of land.
