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.
