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753.910 hm2下降到124.470 hm2；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-environmental mainly performances as the coastal wetland in Yancheng is the key of reclamation, natural wetland area largely lost, the ninth five-years and the tenth five-years reclamation area near the city was 1/3 of the wetland area; the living environment of Red-crowned cranes faced threats, biodiversity declined, the population of red-crowned cranes wintering declined since 2000, wetland ecosystem, the water environment and soil environment in coastal wetland faced the threats.
