松嫩高平原黑土区耕地动态变化特征分析——以黑龙江省巴彦县为例
An Analysis on Dynamic Characteristics of Cultivated Land in Black Soil Region of the Songnen High Plain——A Case Study of Bayan County in Heilongjiang Province
摘要
Abstract
Study on the dynamic characteristics of cultivated land plays a very important role in protection,consolidation and utilization of cultivated land.By taking remote sensing images in 1991,2006 and 2009 as data source,the characteristics of amplitude and speed,roll-in and roll-out,spatial distribution,and landscape distribution of cultivated land changes were analyzed by means of spatial analysis function of GIS.Results show that the total area of cultivated land increased,but the net annual average speed declined in the three years.Unutilized land,forest land and construction land were the main land use types transformed into cultivated land.Cultivated land was mainly transformed into forest land,unutilized land,grassland and construction land.Spatial differences of cultivated land change in Bayan County were remarkable,and newly increased cultivated land was mainly from the reclaimed floodplain along the Songhua River,deforestation of northeast hilly areas and construction land change in northwest.The number and density of cultivated land plaque tended to increase,human interference extent increased,and fragmentation enlarged.Landscape shape index and fractal dimension tended to decrease and the shape of cultivated land landscape plaque became simpler and more regular.The high connectivity of cultivated land landscape indicated that the spatial distribution of cultivated land landscape had a high degree of aggregation.关键词
