摘要
【目的】探明印江县村域"三生用地"不同功能用地的结构和空间分布规律,为区域国土空间结构与功能的优化提供决策依据。【方法】以国家重点生态功能区之一的印江县351个村为解析尺度,按生态、生产和生活用地功能划分土地类型,运用计量地理学和GIS方法,计算"三生用地"多样性、优势度、组合数和组合类型、利用程度和区位度等指标,分析"三生用地"的结构和空间特征。【结果】①印江县村域"三生用地"多样化指数为0.81,多样性程度总体处于中等偏上水平;优势度指数为0.58,优势度总体呈中等偏下的状态。②"三生用地"组合类型集中在生态-生产生态双重组合类型、生产生态-生态的双重组合类型和生态单一类型。③"三生用地"利用程度为231,利用程度总体水平较高。④村域"三生用地"类型的区位差异明显,东部、南部地区生态用地区位优势突出,北部、西北部和中部地区生产生态用地区位优势突出,西部地区生活生态用地区位优势突出。【结论】对土地利用进行"三生用地"分类,运用计量地理模型及多样性、优势度、组合数与组合类型、利用程度和区位度5种指标能够较为全面地反映不同功能用地的结构和空间特征。
【Objective】The present paper aimed to explore the structure and spatial distribution pattern of ecological-living-productive land with different function at village level and provide the decision basis for optimization of spatial structure and function of national land in Yinjiang County.【Method】The diversity,dominance,combination number and combination type of ecological-living-productive land were calculated by taking 351 villages as analysis scales in Yinjiang County,dividing land type according to ecological,productive and living function and using quantitative geography and GPS.The structure and spatial distribution of ecological-living-productive land were analyzed by the indexes of level and location degree.【Result】(i)The diversity index of ecological-living-productive land was 0.81 and the diversity index was at the above-average level overall.The dominant index was 0.58 and the dominance was at the below-average level overall.(ii)The combination types of ecological-living-productive land concentrated upon the ecological-productive ecological double combination type,productive ecological-ecological double combination type and single ecological type.(iii)The utilization degree of ecological-living-productive land was 231 with a higher overall level.(iv)The location difference among types of ecological-living-productive land at village level was obvious.The ecological land in east and south region was of obvious location advantage.The productive-ecological land in north,northwest and central region was of obvious location advantage.The living ecological land in west region was of obvious location advantage.【Conclusion】The structure and spatial distribution of the lands with different function can be calculated by the quantitative geographic model,diversity index,dominance,combination number and type,utilization level and location degree in land utilization classification of ecological-living-productive land.
