| 摘 要： | 在野外调查和资料收集的基础上,利用2000和1988年遥感数据,对我国中东部地区的湿地环境进行评价,结果表明:我国中东部地区湿地类型多,面积大,但分布不均;人工围垦、农业生产活动和水利工程建设是导致中东部地区湿地破坏的主要原因;由于湿地面积缩小,导致湿地功能下降,湿地生物多样性降低,区域洪涝灾害频繁发生.

| Abstract: | Based on field investigation and data collection, and using 2000 and 1988 remote sensing data, the condition of wetland in mid-eastern China was analyzed and assessed. The results show that there are many kinds of wetlands in mid-eastern China, with wide area but uneven distribution; the wetlands have been strongly destroyed mainly by artificial reclamation, agricultural production activities and construction of water conservancy works ; their functions have been reduced and the diversity decreased due to shrinking of the area of wetlands, which has resulted in frequent floods in the region. |
