北京市平谷区不同区域农村居民点内部结构差异分析

本文以北京市平谷区2006 年集体土地调查的数据为基础, 运用景观生态学的研究方法, 对不同区域条件 下农村居民点用地内部结构特征进行分析, 进而揭示农村居民点用地内部结构的地域分异规律, 研究结果表明: 生 产力水平的不同使农村居民点用地内部结构形成不同的地域特点, 就内部结构多样性指数而言, 半山区>平原区> 山区, 就集中性指数而言, 山区>平原区>半山区。同时, 各区域农村居民点内部不同用地类型的区位意义指数也在 发生规律性变化: 就宅基地而言, 山区>平原区>半山区, 就企业用地而言, 半山区>山区>平原区, 就公共管理与公共 服务用地而言, 半山区>山区>平原区, 就空闲地而言, 平原区>山区>半山区。今后新农村建设过程中, 要从各区域社 会经济发展的实际情况出发统筹城乡发展, 着力于合理安排城乡产业用地布局, 并体现土地集约利用的方向; 同 时, 还应根据区域特点的不同采取不同村镇规模控制标准, 提出各自农村居民点用地的调整模式与途径。

Analyzing Land Use Structure Difference of Rural Residential Areas in Different Regions of Pinggu District of Beijing

Based on the collective land survey data in Pinggu,Beijing in 2006,the paper analyzes the inner land use structure in rural residential areas of differential regions with the aid of landscape ecology method,thus revealing its geographical distributions.It shows that the difference in productivity caused the characteristic of land use structure of different regions.As far as the diversity index of inner land use structure is considered,Mid-Levels>plains>mountains.As far as the centrality index is considered,mountains>plains>Mid-Levels.Meanwhile,the location index of different land use types change regularly as the regions change.As far as residence land is considered,mountains>plains>Mid-Levels.As far as factory land is considered,Mid-Levels>mountains>plains.As far as service establishment land is considered,Mid-Levels>mountains> plains,as far as idle construction land is considered,plains>mountains>Mid-Levels.In the progress of new rural area construction in the future,the development of urban and rural should be integrated in the view of arranging the industry distribution reasonably,and reflect the principle of land intensive use.Moreover,different rural residential areas should have different scale control modes and approaches of land adjustment.
