| 摘 要： | 选取重庆市沙坪坝区陈家镇为研究区,采用其建立的土地利用现状数据库,运用GIS的图形处理与空间分析功能,生成6种景观格局图并输入Fragstats for ArcView3.X软件,提取景观格局指数,借助于景观格局指数在生态过程与土地利用间所建立的一种关联,分析并探讨土地利用诱发下景观空间格局特征的响应.其结果:水田景观在景观类型中占据着绝对优势,其连接度表现较高,是景观类型明显的基质,受人类活动干扰强;冬水田景观要素接近于水田景观本底,且冬水田景观要素斑块个数、类型面积随着河流缓冲区距离的增大而增加;旱地景观中各景观要素斑块总体上分布比较零散,规律性不强;农村居民点景观要素是建设用地景观的主要类型,其斑块几何形状简单、规整,各斑块间的相似性强,外围边界接近于正方形或者矩形. |

| Abstract: | Taking Chengjiaqiao Town in Shapingba District,Chongqing as a study area,this paper adopted the current land use database,re-modified the classification of land use,and created six landscape pattern maps relying on the spatial analysis and graphics processing of ArcGis8.3 and ArcView3.2 software.Individual landscape metrics were calculated by function of Fragstats3.3 software.Landscape metrics is seen as a bridge between ecological process and land use,thus the paper analyzed and explored characteristics of landscape pattern resulting from land use.The result indicated that in the study area,the paddy land landscape was dominant landscape types.They were landscape matrix and the main location of human activities,and controlled landscape patterns and their evolvements too.Winter water-stored paddy field landscape element is closely approach to background of paddy land landscape.Moreover,their patch number and area were raised along with the distance of river's buffer zone by Buffer analysis.The patches of dry land landscape element distributed erratically in dry land landscape.Rural settlement landscape element was dominant in the construct land landscape.Their patches are simple,trim,and conform. |
