摘要
海岸带是全球环境变化最为敏感的地区之一,其土地利用变化可引起多种资源与生态过程的改变。随着人口的增加以及经济的发展,烟台市海岸带土地利用变化不断加剧,研究其土地利用空间格局变化对合理利用土地资源、促进沿海地区的可持续发展具有重要意义。利用RS,GIS手段研究分析了烟台市套子湾沿岸景观格局的时空变化及其驱动力因子。对1986,1992,2000和2004年4个时期的TM影像进行了解译。结果表明:套子湾沿岸耕地和林地呈现明显的减少趋势,居民地、果园呈明显增加趋势,水体和滩涂变化不明显。受自然和人类活动的共同影响,景观多样性指数与均匀度均呈现出先上升后降低的趋势,反映出土地利用首先逐渐趋于多样化和均匀化,而后又开始向单一化的趋势发展。
Coastal zone was one of the most sensitive regions in global environment change. Most of the physical phenomenon and ecological process changes in coastal zone took place because of the coastal land use changes. The land use change of the seacoast in Yantai City had been strengthened along with the increase of population and the development of economy. The study of its land use and cover pattern dynamics has great significance to the utilization of land resources and sustainable development. The paper mainly dealt with the spatial-temporal variation and driving force of the landscape pattern of study area with the technique of remote sensing and GIS. Four TM images in 1986, 1992, 2000 and 2004 were interpreted. The results showed that the areas of plow land and woodland decreased obviously; the residential area and orchard area increased significantly; there was no significant change in water area and bottomland. The SHDI, SHEI indices represented the trend of increasing at first and then turning to decrease which reflected that the land use pattern tend to diversification and uniformity at first and then went in the opposite way.
