摘要 自然和人为因素引起的滨海湿地生境变化是我国面临的重要问题。大片沿海栖息地正在消失，而剩下的栖息地则容易受到工业、农业、水产养殖、城市发展和生活垃圾的人为影响。一个问题是栖息地面积的变化是否会对自然保护区的边界调整产生影响。本文报告的研究应用遥感图像、环境和社会经济数据来分析1988年至2008年河口地区土地利用、土地覆盖和生境质量的变化，并确定这些变化的驱动力。结果表明，这一时期土地利用发生了显着变化。耕地面积由1988年的36,879.0公顷减少到1999年的35,313.7公顷，占总面积的35.96%。居民点面积由1988年的11,305.1公顷扩大到1999年的16,661.3公顷，2008年进一步扩大到23,258.6公顷。 1988年至1999年，聚落、咸水体和未利用土地分别增加了47.38%、33.51%和16.66%。1999年至2008年，这种趋势持续存在。2003年的平均总生物量远低于1983年同一区域的生物量，生物密度也急剧下降。 1993年至2006年，大港区的国内生产总值和人口持续增长，是栖息地变化的主要驱动力。滨海湿地生境质量与自然保护区边界相关，应根据实际保护状况进行调整。边界调整的建议也有助于提升滨海湿地生境质量。本研究强调通过边界调整来改善沿海环境。
Abstract Habitat change of coastal wetlands caused by natural and anthropogenic factors is an important issue facing China. Large areas of coastal habitat are disappearing, and those remaining become vulnerable to anthropogenic impacts from industry, agriculture, aquaculture, urban development, and domestic waste. A question is whether the change of habitat area has an influence on boundary adjustments of natural reserves. The study reported in this paper applied remote-sensing images, and environmental and socioeconomic data to analyse the change of land use and land cover and habitat quality in an estuarine area and to identify the driving forces for these changes from 1988 to 2008. The results show that land use has changed significantly over this period. Cultivated lands occupying total area 35.96% decreased from 36,879.0 ha to 35,313.7 ha from 1988 to 1999. The area of settlements expanded from 11,305.1 ha in 1988 to 16,661.3 ha in 1999 and further to 23,258.6 ha in 2008. The areas of settlement, saltwater bodies, and unused land increased by 47.38%, 33.51%, and 16.66%, respectively, from 1988 to 1999. These trends continued from 1999 to 2008. The total average biomass in 2003 was far below the biomass of the same region in 1983 and the biological density also decreased sharply. The gross domestic product and population of the Dagang District grew continuously from 1993 to 2006 and was the main driving force of habitat change. The habitat quality of coastal wetlands is associated with natural reserve boundaries, which should be modified according to the actual protection status. The suggestion of boundary adjustment has also assisted the enhancement of habitat quality of coastal wetlands. This research emphasises the improvement of coastal environments through implementation of boundary adjustments.
