摘要：对福建漳江口红树林湿地保护区1992年、1996年、2001年和2008年4个时期LandsatTM影像数据分别进行校正和配准,然后选用波段比值法进行红树林信息提取,并根据植被指数和植被覆盖度的关系模型估算保护区植被覆盖度。并针对保护区红树林面积的时空变化特征和植被覆盖度空间格局变化,分析红树林湿地保护对策。结果表明:近十几年来,红树林面积逐渐增加,以大斑块的增加较为明显,红树林分布趋于集中。其中,以2001～2008年间红树林面积增长最多,而1992～1996年间面积增长最快。保护区中高植被覆盖度呈总体增加趋势,低植被覆盖面积比降低。从植被覆盖面积构成来看,中高植被覆盖面积比达80%以上。针对保护区红树林面积和空间变化特点,结合当地实际情况,提出合理的湿地保护对策。
To understand the spatial and temporal dynamic characteristics of mangrove wetland reserve Zhangjiang Estuury in Fujian Province, this paper employed the bands ratio algorithm to classify the man- grove forest by using the calibrated ＆ registered landsat TM images of 1992,1996,2001 and 2008. The vegetation coverage of the region was estimated by means of relation model between vegetation index and vegetation coverage. The protection countermeasures of mangrove wetland were suggested according to the dynamic changes of mangrove area and vegetation fraction. The conclusions are as follows：The mangrove area had been increasing gradually in recent 16 years, the changes of large patches were obvious especially, and the spatial distribution of the mangrove forest tended to be concentrated. The area of the mangrove forest changed mostlg between 2001 and 2008, and the changing rate of the mangrove area was the greatest between 1992 and 1996. The middle and high vegetation coverage of the mangrove wetland reserve was in- creasing, but the low vegetation cover was decreasing. The percentage of the change area of the middle and high vegetation cover was more than 80%. According to the characteristics of temporal and spatial varia- tion and local situations, the proper measures of wetland protection were proposed.
