| 摘 要： | 海岸带景观是沿海地区社会经济可持续发展的基础,研究人类活动影响下的海岸带景观生态风险演变对海岸带景观规划与景观资源的合理开发具有重要意义。本文基于1990—2010年间3期的Landsat TM/ETM+遥感数据源,结合野外实地调查,研究了象山港海岸带景观生态风险及其变化趋势。结果表明: (1)20 a间,象山港海岸带景观格局发生显著变化,耕地、海域和林地等景观类型面积呈下降趋势,而建设用地、未利用地和养殖用地不断增加;(2)1990年以来,象山港海岸带景观生态风险等级有不断增高趋势,部分低、较低等级生态风险区演变为中等级以及较高等级;(3)从不同等级生态风险区的空间分布上看,1990年以来海岸带景观低和较低等级生态风险区空间分布在沿海地区减少,而中等、较高和高生态风险区在沿海地区不断形成并向陆侧扩张。从演化速率上看,近10 a的较高和高生态风险区面积增加速率较前10 a显著加快。

| Abstract: | Coastal landscape is the foundation of sustainable social and economic development in coastal areas .It is significant to make a analysis change of landscape ecological risk on coastal zone to optimize the evolution of the coastal landscape planning and rational development of landscape resources. The study, based on the Landsat TM/ETM+ remote sensing data of 1990-2010 and field survey ,analyzes the temporal-spatial change of landscape ecological risk on coastal zone of Xiangshangang bay. The results show that: (1) Over 20 years, Great changes of landscape patterns have taken place in Xiangshangang bay . The area of arable, sea, woodland decreased. While the area of construction land, unused land and farming land increased. (2) Since 1990, Xiangshangang coastal landscape ecological risk grade has constantly increasing trend. Some low, low grade of ecological risk area evolved in high grade and extremely high grade.(3) Judging from different levels of ecological risk from space area distribution ,It embodies in the space that the extremely low and low grade ecological risk areas shrink to upstream during 1990~2010, and the area show a downward trend. The medium, high and extremely high grade ecological risk areas expand to the coastal areas. In terms of the evolutionary rate, nearly 10 years of high and extremely high ecological risk area has significantly accelerated the rate of increase over the previous 10 years. |
