2 200 a BP以前,江汉-洞庭湖平原是一个完整的湿地生态系统,在人类活动影响下,其湿地空间逐渐由平原边缘向腹心萎缩,水陆交错型湿地之生物多样性的破坏早于水体型湿地之生物多样性的破坏,耕地转化是湿地空间萎缩和湿地生物多样性损失的主因.从湿地历史变迁看,江汉-洞庭湖平原现有湿地的保护与可持续利用必须:调整传统的"国家粮仓"的区域战略定位,实施湿地生态大农业和湿地生态旅游发展战略;加强湿地效益的宣传教育,提高湿地保护与可持续利用的政府决策能力和公众参与水平;协调耕地保护与湿地保护关系,推行湿地总量动态平衡制度;优化湿地生态系统的整体功能,将退田还湖作为区域发展的一项长期战略...

The JianghanDongting Plain in Hubei and Hunan provinces constituted a huge ecosystem of wetlands 2200 years ago. With the impacts of historically human activities, the extent of natural wetlands has been gradually atrophied from edge to center of the Plain; the deterioration of biodiversity in the waterland interlaced wetlands was earlier than that in the waterdominant wetlands; and farming conversion was a primary cause of the spatial atrophy and biodiversity deterioration of wetlands. From the historical process variation of wetland var...
