摘要
为实现县域范围内土地合理开发利用,对其土地利用及空间分布特征进行综合分析十分必要。本文以浙江省宁波市鄞州区为研究区,以ArcGIS为分析平台,利用2011年该区土地利用现状数据,运用计量地理模型探讨其土地利用总体组合类型、土地利用综合程度及各地类的区位意义,以表征各乡镇土地利用的数量特征,进而分析其空间格局特征。结果表明:研究区土地利用的数量特征总体存在一定的差异性,各地类中耕地和园地的区位意义较为突出;空间格局的总体特征表现为各地类斑块的形状总体较为复杂,其中耕地、林地的形状较规则且分布集中连片,为该区域的景观基质,园地、城镇用地和草地的分布最为离散。
It＇s necessary to study land use characteristics and its spatial distribution of the study area.In this paper,take Yinzhou District,Ningbo City,Zhejiang Province as the study area,based on the land use map of Yinzhou district in2011,the land use overall combination types、land use comprehensive degree and the regional meanings of each land use type were used to explore the quantity characteristics of land use of the 24 towns of Yinzhou.The results showed that land use quantity characteristics existed certain differences in overall,the land use combination type of 24 towns showed weakly for the overall land function.Land use degrees showed a big difference,and the regional meanings of cultivated land and garden land were prominent relatively.The general characteristics of spatial distribution showed relatively complex of all the patch shapes.Water area,other land and forest land were relatively regular and intensively distributed,which were regional landscape matrix,while garden land,residential and industrial land and grass land distribute most discretely.
