【摘要】：為深入揭示煙臺市海岸線40年時空變遷及土地利用空間格局變化,采用Landsat MISS,TM,ETM+遙感數(shù)據(jù),對煙臺市4個時期海岸線進行了長度提取,以海岸線向陸地延伸5km作為研究范圍,結(jié)合地形圖和土地利用調(diào)查數(shù)據(jù),運用監(jiān)督分類提取了1973年和2014年兩個時期土地類型,分析了土地利用現(xiàn)狀和時空變化;在此基礎(chǔ)上,應(yīng)用Costanza的生態(tài)服務(wù)價值計算方法,參考中國陸地生態(tài)系統(tǒng)景觀單位面積生態(tài)服務(wù)價值表進行了貨幣化計算評估。結(jié)果表明:(1)1973—2014年海岸線總體長度呈遞增趨勢,40年間凈增了55.976km,其中人工岸線增幅最大,而基巖和淤泥質(zhì)自然岸線大幅減少;(2)40年間總土地面積凈增了95.661km~2,主要是填海造陸導(dǎo)致建設(shè)用地面積增加,而濕地、林地和水體等生態(tài)用地面積大幅減少;(3)土地利用變化導(dǎo)致生態(tài)服務(wù)總價值損失了158.636萬元,其中濕地、林地的生態(tài)服務(wù)價值損失最多。自然濕地大量轉(zhuǎn)化為建設(shè)用地以及大力保護耕地是導(dǎo)致不同土地覆蓋類型生態(tài)服務(wù)價值發(fā)生變化的主要原因。
[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.
