河北省农用地质量空间格局的计量地理分析
- Title:
- Analysis on Spatial Pattern of Agriculture Land Resources Quality in Hebei Province Based on Quantitative Geography Model
- 分类号:
- F323.211
- 摘要:
- 在农用地分等成果的基础上,采用GIS技术、计量地理学分析相结合的方法,对河北省农用地资源质量的空间格局进行定量研究：从河北省不同指标控制区农用地资源质量的多样性、集中度、均匀度、优势度等分布特点来看,河北省农用地质量空间格局呈现从东南到西北方向上的递变规律,即东南部平原区农用地资源质量各等别面积比例较为平衡均一,而西北部坝上地区集中程度较高;同时针对各指标控制区农用地资源质量结构提出各区土地利用的方向,为河北省农用地资源的合理利用提供科学依据;最后对影响农用地质量空间分布的气候、地形地貌等自然因素影响及人类活动的干扰作用进行分析.
- Abstract:
- Based on the database of agricutural land classification in Hebei province,we studied the spatial pattern of agriclutural land resource quality and analyzed its affecting factors through the methods of GIS and quantitative geography model.By evluating the index of diversity,centrality,superiority and homogeneity of agriculture land resource quality in different index-control regions,we found that the spatial pattern of agriclutural land resource quality showed decreasing tendency from southeast to northwest:the area ratio of each grade in Southeast plain area is equalization,while the concentration degree in north-west dam area is high.The paper also proposed the land using direction according to the quality structure of agriculture land resource in different index-control regions,in order to provide a scientific foundation for agricultural land resource rational use.Finally,we analyzed the factors which affected the spatial distribution of agriculture land quality,such as climate,topography and other natural factors and human activities.
