发达地区镇域土地利用碎片化测度研究--以中山市东升镇为例

摘要

对中山市东升镇土地利用碎片化形态及其形成过程进行量化分析，以准确刻画其土地利用格局，探析碎片化的主要影响因素，作为进一步剖析其碎片化形成机制的实证基础。借用景观生态学的“斑块”概念及研究方法，运用Fragstats软件工具进行城乡用地格局的数理统计运算。发现东升镇土地利用碎片化主要作用因素是多年来大量分散增长的工业用地和农村居住用地，而占据主要比例的大量细碎用地斑块是其碎片化格局的直接原因。以期为半城市化地区土地利用研究提供新的视角和方法。%A quantitative analysis is launched on the characteristics and formation of land use fragmentation of Dongsheng to characterize the land use pattern accurately and to ifnd out the main inlfuencing factors, that aims at the driving forces of Dongsheng’s land use fragmentation. This paper measures the land use fragmentation of Dongsheng using the Fragstats program based on the“patch”and the method of landscape ecology. It concludes that the main forces inlfuencing Dongsheng’s land use fragmentation include the industrial land using and rural house land using which sprawled rapidly over the years, and the high proportion of fragments of land use is the most important reason of the fragmentation. This paper provides a new perspective and method for the analysis of land use of peri-urbanization areas.
