Research on Landscape Pattern Change of Land Use in Lianyungang Coastal Zone Based on Remote Sensing

摘要

With the increase of population in Lianyungang, and economic development of coastal land use change continues to accelerate, study of land use pattern changes on the rational use of land resources is important. In determining the scope of the study and land use classification system, based on the use of ArcGIS to the 1987, 2000 and 2009 three times to understand translation of TM/ETM images to produce three phases of land use classification map. From the landscape level and landscape level 2 levels, select the patch area, the proportion of plaque area, mean patch fractal dimension, landscape diversity, landscape evenness and landscape dominance index, the coastal zone of Lianyungang, between 1987-2009 landscape pattern change of land use laws. The results show that: arable land, salt pan area decreased, filling sea land, building land, garden grass, water area, aquaculture, unused land area was increasing. Downward trend in the uniformity of the case, the landscape diversity and dominance are rising.
