广东省土地利用结构的地域差异研究

The studies of the different regional land-use structure of Guangdong Province

采用广东省所辖21个地级市2005年土地利用变更调查资料中二级分类的用地面积和比例作为研究的基础数据,并按主导性、差异性、稳定性和景观差别性原则进行必要处理和整合,运用景观生态学方法和组合系数法进行土地利用结构的定量和定性分析,以此揭示区域土地利用结构的地域差异,研究结果呈现以下规律:土地利用多样性和土地利用组合类型数由南部沿海城市向中北部城市依次递减,而土地利用的集中程度则大致相反;土地利用的组合类型与区域的经济发达程度呈正比例相关,经济越发达的南部地区,土地利用类型组合数越大,反之,经济不发达的北部山区,组合数很小。

Field area and proportion is adopt to classify two steps in what Guangdong province has 21 downtown area land-use in 2005 alteration under command inquiring into a data are the basis data studying.And difference principle carries out necessary treatment according to the leading factor,difference,stability and landscape and integrates,And then,the ecology method and combination modulus wielding landscape follow architectural quantify and qualitative analysis carrying out land utilization,reveal architectural region of area land-use difference on this account.Study result displays the following law： Land-use diversity and the land-use combination type number decrease by degrees in proper order from the southern part coastal city to middle north part city;But land-use＇s concentrating degree is basically contrary.The land-use combination type and developed degree of the area economy assume the direct proportion relevance.Developed southern part of economy area,the land-use type combination number is increasingly big,on the contrary,underdeveloped economy north part mountain area,the combination number are very minor.
