东南沿海低山丘陵区土地利用结构的地域分异研究——以温州市为例

STUDY ON DIVISION OF REGIONAL LAND USE STRUCTURE IN THE COASTAL AREA OF LOW MOUNTAINS AND HILLS IN SOUTHEASTERN CHINA—A CASE STUDY IN WENZHOU CITY

根据土地利用详查变更资料中二级分类的用地面积和比例 ,采用景观生态学结构定量分析方法 ,以温州市为例对东南沿海低山丘陵区土地利用结构的地域分异进行了定量研究。研究结果表明 :(1 )前述方法能够很好地揭示区域土地利用结构的地域分异 ,其结果能在一定程度上反映研究区自然条件、自然资源和社会经济发展地域结构的差异 ;(2 )研究区土地利用结构的区域变化呈以下规律 :土地利用结构的多样性和土地利用组合类型数由沿海向内陆、平原向山区、城市近郊向远郊依次递减 ,土地利用结构的集中度则刚好相反 ,土地利用的组合类型与区域的经济活动特点相关等 ;(3 )研究区土地利用结构区域差异主要受地理位置、地貌状况、区位条件、经济发展水平等因素的强烈影响。

Summary The division of regional land use structure in the coastal area of low mountains and hills of southeastern China was studied in this paper by the quantified structure analysis method of landscape ecology, according to the square and ratio of second class land types of the detailed land use investigation and a case study in Wenzhou City. The results showed: (1) the division of regional land use structure can be revealed well by the above mentioned method, and those results can show the regional structural differences of natural condition, natural resources and socio economical development in the study area; (2) the regional change of land use structure in the study area saw the following regular patterns: the structural diversity and composed types of land use decrease by degrees from coastal area to inland area, from the plain area to the mountain area and from nearby suburbs to far suburbs, but the centrality of land use structure is on the contrary, and composed types of land use are related with the features of regional economical activities; (3) the regional differences of land use structure in the study area are influenced strongly by the geographical place, geomorphologic situation, location advantage, level of economical development and other factors.
