中文摘要:
      利用1985年、1995年、2005年和2018年4期遥感影像获取了海口全市湿地数据,在湿 地类型转移矩阵和主成分分析基础上较系统地剖析了近30年来海口市湿地动态变化过程及其驱 动力。结果显示:(1)1985—2018年海口市湿地总面积共减少了10 409.98 hm2,减幅达13%,水田、 河流湿地、近海与海岸湿地以及库塘湿地等湿地类型面积减少显著;(2)湿地空间变化显著区由沿 江向沿海转移,2005年以前全市湿地变化主场区集中于南渡江以东地区,2005年及其以后南渡江 以西地区生产性人工湿地类型有少量增加;(3)滨海地区在1985—1995年、1995—2005年和2005— 2018年3个时段均有湿地变化,但1995—2005年滨海地区的湿地空间变化范围、强度均明显大于 其他两个时期;(4)社会经济因素是造成海口市湿地变化的主要原因,其中人口增长、城镇扩张和 经济规模扩大是导致全市湿地面积减少最主要的驱动因子,水产养殖业发展是改变海口市湿地景 观格局的重要因素。
英文摘要:
      The wetland data of Haikou were obtained by using the remote sensing images of 1985, 1995, 2005 and 2018. Based on the transfer matrix of wetland types and principal component analysis, the dynamic change process and driving forces of the wetland in Haikou in the past 30 years was systematically analyzed. The results showed that: (1) The total area of wetland in Haikou decreased by 10 409.98 hm2 from 1985 to 2018, with a percentage of 13%. The area of wetland types such as paddy fields, rivers, offshore and coastal wetlands decreased significantly. (2) The significant change area of wet⁃ land changed from riverside to coastal. Before 2005, the main area of wetland change was concentrated in the east of Nandu River, since then the productive constructed wetland type in the west of Nandu River has been slightly enhanced. (3) There were wetland changes in coastal areas in 1985—1995, 1995—2005 and 2005—2018, but the spatial variation range and in⁃ tensity of wetland in coastal areas between 1995 and 2005 were significantly larger than those in the other two periods. (4) Among the factors that affect wetland changes, socio-economic factors are the main causes of wetland changes in Haikou. Among them, population growth, urban expansion and economic scale expansion are the main driving factors leading to the shrinkage of wetland area in Haikou, and the development of aquaculture is an important factor to change the landscape pattern of wetland in Haikou.
