【摘要】：为深入揭示烟台市海岸线40年时空变迁及土地利用空间格局变化,采用Landsat MISS,TM,ETM+遥感数据,对烟台市4个时期海岸线进行了长度提取,以海岸线向陆地延伸5km作为研究范围,结合地形图和土地利用调查数据,运用监督分类提取了1973年和2014年两个时期土地类型,分析了土地利用现状和时空变化;在此基础上,应用Costanza的生态服务价值计算方法,参考中国陆地生态系统景观单位面积生态服务价值表进行了货币化计算评估。结果表明:(1)1973—2014年海岸线总体长度呈递增趋势,40年间净增了55.976km,其中人工岸线增幅最大,而基岩和淤泥质自然岸线大幅减少;(2)40年间总土地面积净增了95.661km~2,主要是填海造陆导致建设用地面积增加,而湿地、林地和水体等生态用地面积大幅减少;(3)土地利用变化导致生态服务总价值损失了158.636万元,其中湿地、林地的生态服务价值损失最多。自然湿地大量转化为建设用地以及大力保护耕地是导致不同土地覆盖类型生态服务价值发生变化的主要原因。
[Abstract]:In order to reveal the spatial and temporal changes of the coastline and the spatial pattern of land use in Yantai for 40 years, the length of the coastline in four periods of Yantai city was extracted by using Landsat MISS,TM,ETM remote sensing data, and the study scope was to extend the coastline to land by 5km. Combined with topographic map and land use survey data, land types in 1973 and 2014 were extracted by supervised classification, and land use status and temporal and spatial changes were analyzed. On the basis of this, the calculation method of ecological service value of Costanza was applied. With reference to the value of ecological services per unit area of terrestrial ecosystem landscape in China, the monetization calculation and evaluation are carried out. The results showed that: (1) the total length of coastline in 1973-2014 showed an increasing trend of net increase of 55.976km in 40 years, in which artificial shoreline increased the most. However, the natural shoreline of bedrock and silt decreased significantly; (2) the total land area increased by 95.661km2 in the past 40 years, which was mainly caused by reclamation, which resulted in an increase in the area of construction land, but in wetlands, The area of ecological land such as forest land and water body decreased significantly. (3) the total value of ecological services lost 1.58636 million yuan due to the change of land use, among which wetland and woodland lost the most value of ecological services. The transformation of natural wetland into construction land and the protection of cultivated land are the main reasons for the change of ecological service value of different land cover types.
