摘　　要：利用不同时期的遥感数据(包括卫星遥感与航天遥感),结合研究区文献资料和野外调查,利用GIS的空间分析功能,对武昌湖地区近年来的生态环境变化的特点进行分析.指出武昌湖存在①湖区面积缩小,湖底不断淤积;②湖面已开始出现沼泽化趋势;③调洪蓄洪能力减弱;④生物多样性下降等生态环境问题,阐述了这些变化产生的原因.文章最后还结合实际情况提出了一些对策建议,力图使武昌湖地区的生态环境向着良性循环的方向发展变化.Based on satellite remote sensing data of different period, making use of geographical information, the ecosystem environment change in Wu-chang Lake is analyzed. There are some useful results： ①the area of lake is contracted and the bottom has seriously silt up ②a swampy tendency has appeared in the west of the lake ③the ability of regulating and storing flood has dropped ④ living creature variety has descent. Meanwhile, the paper analyzes the reason for the change. At last, based on actual circumstance, the paper gives some feasible advice to protect and develop the lake resources. In short , the paper suggests that a sustainable development may be a better choice.
