摘要
采用定性与定量相结合的方法,根据实地调查和华南地区的年鉴资料,从湿地面积、湿地时空动态变化、湿地景观格局变化3个方面,对近20年间华南地区湿地的现状及变化趋势进行了系统的研究分析,并探讨了导致华南地区湿地发生变化的影响因子,进而提出了针对华南地区湿地保护的措施。结果表明,华南地区湿地以天然湖泊、河流等湿地为主,其次是人工湿地。在气候、社会、文化等因素的影响下,华南地区原始自然湿地面积锐减43%,湿地类型也发生了显著变化,并带来了一系列生态问题。
According to the field surveys and Southern China Yearbook data, we used a qualitative and quantitative combination method in this paper. From the three aspects of wetland area, wetland spatially and temporally dynamic changes and wetland landscape pattern changes, we researched and analyzed the status and trends systematically of wetlands in Southern China in past 20 years. Then we explored the influencing factor of wetland changes in Southern China, and then presented protection measures. The results showed that the wetlands in Southern China were mainly natural lakes and rivers wetlands, followed by artificial wetlands. Under the influence of climate, society, culture and other factors, original natural wetland area in Southern China decreased by 43%. The types of wetlands had also undergone an significant change and a series of ecological problems appeared.
