论邻接类型对土地利用变化的影响——以长沙市望城区为例

Influence of Adjacent Types on Land Use Change——A Case Study in Wangcheng County,Changsha City,Hunan Province

以长沙市望城区为研究区域,依据土地利用二级分类标准,定量研究不同时间段内(2009—2010、2010—2011、2011—2012)土地利用类型的变化情况,分析每个变化斑块与其邻接类型之间的关系。从斑块数量上来说,变化后的斑块类型是其邻接类型占比的24.50%;从斑块面积上来说,变化后的斑块类型是其邻接类型占比的34.16%。因此,邻接类型对土地利用变化有一定影响,在驱动力分析和土地利用模拟预测过程中要考虑邻接类型对土地利用变化的影响。

Taking the Wangcheng County as a case study area,and according to the second category of land use classification standard,this study tries to quantitatively study changes of land use types in different time periods（ 2009—2010、2010—2011、2011—2012） and analysis of relationship between land use change and adjacent land use types. From the number of patches,the percent of the number of type after change which is the same as its adjacent type before change is24. 50. Similarly,from the area of patches,the area of type after change which is the same as its adjacent type accounted for 34. 16 percent. Thus,the type of adjacent land will have an impact on land use change,and in the driving force analysis and land use simulation and forecasting process,it is best to consider the impact of land adjacent type on land use changes.
