安徽省大别山集中连片特困区土地利用结构的多维计量分析

Analysis on Structure of Land Use in Dabieshan Mountain's Contiguous Poverty-stricken Area in Anhui Province

采用安徽省大别山集中连片特困区2011年12个区县的土地利用详查变更数据,运用计量地理学模型和GIS空间分析技术等方法,对土地利用空间结构进行深入分析,结果表明:研究区土地利用结构多样化指数空间差异较为显著,由南向北呈递阶变化特征;集中化指数与优势度空间上大体一致,而均匀度与优势度、集中化空间呈现相反分布特征;土地利用程度呈现从南向北逐渐升高的空间特征,但土地利用组合类型数差异较大且复杂多样;土地利用信息熵表现为南部较高、中北部地区较低的空间特征。

Based on the changed detailed investigation data of land use in Dabieshan Mountain′s contigu-ous poverty-stricken area of 12 counties in Anhui province , using quantitative geography model and GIS spatial analysis techniques ,it probed into in-depth analysis of spatial structure of land use in the paper . The results showed the diversity index of structure of land use in the studied area showed significant re -gional differences and the gradient spatial characteristics from the south to the north as a whole .Central-ized index is in direct proportional relationship to dominance approximately ,while evenness is in inverse proportional relationship to dominance and centralization generally .The extent of land use showed a grad-ually rising spatial characteristics from the south to the north , but the types of combination of land use showed great complexity and diversity .Land use information entropy showed southern higher and north-central region lower of the spatial characteristics .
