摘要
以1987年和2005年SPOT遥感影像为数据源,采用GIS/RS技术对黑龙江省大庆市土地利用变化进行分析,并分析其对生态环境的影响。结果表明:1987-2005年大庆市未利用地、建设用地、耕地和林地呈增加趋势,草地和水域呈减少态势;土地利用时空分异的整体处于微小差异和一般差异;土地利用变化导致土壤质量和大气质量下降,水体严重污染,生物多样性减少,土地利用景观结构趋于均匀分布;土地总生态承载力呈增加态势,但人均生态承载力明显下降。
With the SPOT remote sensing images of 1987 and 2005 as the data source, this paper analyzes land use change ano its eco environmental effect of Daqing City by means of GIS/RS. The results indicate that unused land, construction land, cultivated land and forest land assumed an increase trend from 1987 to 2005, while grass land and water areas were decreasing. The spatial temporal differences of land use were tiny difference and general difference. Land use change has led to the decrease of soil quality and atmosphere quality and to severe water pollution and bio-diversity decrease, the landscape structure of land use tending to uniform distribution. The total land ecological capacity has an increase trend, but ecological capacity per capita obviously decreases.
