摘要
利用2000年哈尔滨市1/25万TM遥感数据,运用景观生态学原理,根据各类景观参数,从斑块和景观水平上分析哈尔滨市土地利用景观格局。结果表明:哈尔滨市的基质景观为耕地;耕地和建设用地斑块边缘密度大,边缘复杂,连接性好;林地、草地、水域和未利用土地斑块边缘密度小,边缘简单,连结性差,受人类干扰弱;从总体上看,斑块总数下降,多样性也下降,土地利用向平原区水田景观要素集中。
In this paper, we analysis on landscape pattern of land use in Harbin, based on the 1/250 000 TM remote sensing image of Harbin in 2000. Used various types of landscape parameters, we calculate the indexes including patch area, number of patch, patch density, edge index, shape index, connection index and diversity index on levers both of Patch and Land. It shows： 1 ） Farmland is the matrix of the landscape. 2） The land patches of farmland and land used for construction have complicated edge, high edge density, good connection. 3） The land patches of woodland, grassland, water area, unutilized land have simple edge, low edge density, bad connection. In conclusion, both the amount of patches and diversity are decreased, and the area of plain paddy landscape element is increased.
