| 摘 要： | 运用GIS和RS技术,通过对1987-2007年盐城海滨湿地景观变化进行比较,分析其景观变化及生态环境响应。结果表明：（1）盐城海滨湿地景观受人为干扰强度增大,景观破碎化明显。1987-2007年平均斑块面积由753.910hm2下降到124.470hm2;平均分维数由1.036降到1.027。（2）海滨湿地生态环境响应主要表现为：盐城海滨湿地是围垦的重点,自然湿地面积大量丧失,＂九五＂和＂十五＂期间围垦面积近全市湿地面积的1/3;丹顶鹤等栖息物种生境面临威胁,生物多样性下降,2000年以来丹顶鹤越冬种群数量呈波动下降;湿地生态系统退化,海滨湿地水环境、土壤环境面临威胁。

| Abstract: | By using GIS and RS technology,the coastal wetland landscape changes of Yancheng form 1987 to 2007 were compared,its landscape changes and effect of ecological environment were analyzed.The result indicated that:(1) the coastal wetland landscape in Yancheng was disturbed intensively by human activity,landscape fragmentation was obvious.During 1987-2007,the average pattern area changed from 753.910 hm2 to 124.470 hm2;the average dimension varied from 1.036 to 1.027;(2)the response of coastal wetland eco-envi... |
