宝泉岭垦区土地利用数量结构特征分析

Analysis on Quantitative Structural Characteristics of Land Use in the Baoquanling Reclamation Area

宝泉岭垦区是我国重要的粮食生产基地,选用相关定量指标并借助GIS技术,对宝泉岭垦区2009年土地利用数量结构特征进行分析,以期为垦区土地利用规划的编制提供参考,为垦区土地利用管理和政策制订、实现区域土地合理开发利用提供科学依据。结果表明:全垦区土地利用多样化指数不高,集中化指数则较高,组合类型和洛伦兹曲线表明,宝泉岭垦区土地利用组合类型只有三种,即:耕地,耕地+林地,耕地+水域及水利设施用地;土地利用类型齐全程度较为单一。通过GIS空间分析,定量阐明了13个农场地类区位意义。宝泉岭垦区土地利用程度指数在265.54～291.56之间,其中有8个农场高于垦区276的平均水平,土地利用程度较高。

Baoquanling reclamation area is an important grain production base of China.Quantitative indices combining with GIS technology were selected to analyze the quantitative structural characteristics of land use of Baoquanling Reclamation in 2009 in order to plan reclamation area of land use,provide reference for reclamation area of land use management and policy formulation,realize the regional land the rational development,and provide the scientific basis for utilization.The research results showed that the diversification indices of each farm were not relatively high,while centralization indices were generally high in the whole reclamation.The combination of land use types and Lorenz curve showed that the combination of land use types were only three.That was cultivated land,cultivated land ＋ foreland,and cultivated land ＋ waters and water conservancy facilities.The complete degree of land use types was relatively single.The quantitative GIS spatial analysis illuminated the location significance of 13 farm land types.Land use degree index was between 265.54 to 291.56.And the degree indices of 8 farms were higher than the average level of 276 farms in the reclamation area,a higher degree of land use.
