高州市土地利用结构的地域差异研究

根据2010年第二次土地调查成果数据,利用景观生态学中的方法定量分析高州市土地利用结构的地域差异.结果表明,研究区土地利用结构自东北向西南逐渐递变,其中多样性和均匀度逐渐增大,土地利用组合类型数增多,而集中化、优势度逐渐减小;各区域优势土地类型存在差异,东北部以林地为主,中部为园地,西南部为耕地;各镇土地利用组合类型数从1～5类不等;研究区土地利用结构区域差异的成因主要包括地形地貌、区位条件和经济发展水平.定量计算方法能较好地反映一定区域内不同局部土地利用结构差别,可以为区域内土地利用分工协作提供很好的研究工具.

Study on Regional Differences of Land Use Structure in Gaozhou City

According to the second land survey achievements data of Gaozhou City in 2010,using the method of landscape ecology,the regional differences of land use structure of Gaozhou City were analyzed quantificationally.The results showed that the land use structure changed gradually from northeast to southwest in the study areas,among which the structural diversity,homogeneity and composed types of land use structure increased gradually,however,the centrality,superiority of land use decreased by degrees,different areas have different preponderant land types,in the northeast,mainly in forest land,in the central,garden land occupied most,and in the southwest,mainly in arable land;the types of land use combination in each town were from 1 to 5;the regional differences of land use structure in the study areas were influenced strongly by the geomorphologic situation,location advantages and level of economical development.The quantitative calculation method can reveal the regional differences of land use structure well,which can provide better research instruments for regional land use division and cooperation.
