20世纪后期黄河三角洲高效生态经济区土地利用结构变化分析
Analysis on Change of Land Use Spatial Structural Characteristics of High-Efficiency Ecological Economic Zone in Yellow River Delta in the Late 20 Century
摘要
Abstract
Based on the 1 km X 1 km scale land use/land cover data, land use/land cover diversity index, land use extent comprehensive index and vegetation cover index were applied to analyze the spatial structural characteristics and heterogeneity of land use (for the year 1980s, 1995 and 2000) and its change (from 1980s to 1995 ; from 1995 to 2000) of high-efficiency ecological economic zone in Yellow River Delta, which were visually shown in the form of images. The results showed that from 1980s to 2000, farmland area decreased in 1995 and returned to the 1980s' planting area in 2000, and the mutual conversions mainly happened between farmland and the reservoir and pond aquaculture land, farmland and urban and rural residential and industrial land, farmland and unused land. The areas of forest land and grass land had a little change. The urban and rural residential and industrial land has remained relatively stable since the area extended in 1995. The areas of tidal flat and salt-affected soil strongly changed from 1980s to 2000. The spatial patterns of land use/land cover diversity indices, land use extent comprehensive indices and vegetation cover indices of 1980s, 1995 and 2000 were basically similar. In general, land use changes of Wudi County, Zhanhua County, Kenli County, Dongying District and Laizhou City located at the coast of high-efficiency ecological economic zone in Yellow River Delta were strong, and these areas were the most active areas. The change trends of land use extent comprehensive indices and vegetation cover indices between 1980s and 1995, 1995 and 2000 were basically the same, especially at the coastal zone of Kenli County and Dongying District, which reflected that land use development and vegetation protection in the region could be achieved together.关键词
