基于景观生态学的土地利用景观格局特征分析——以磐石市为例

以2009年土地利用数据,在地理信息系统平台下,结合景观空间格局分析软件包Fragstats3.3,结合景观面积、斑块个数、斑块密度、平均斑块面积等景观特征指数、计算公式,从景观斑块面积特征,景观斑块密度大小及差异特征,景观斑块多样性、均匀度特征方面,对磐石市土地利用景观格局特征进行分析。结果表明:磐石市土地利用结构以林地和耕地为主,建设用地利用率不高,土地后备资源不丰富。在此基础上,就磐石市建立可持续发展的土地利用规划,增加景观的稳定性问题提出相关建议,强调应调整土地利用结构,提高土地生产力;合理布局农村居民点用地,加强废弃工矿用地整理;合理安排重点城镇用地规模。

Analysis of Landscape Pattern Feature of Land Use Based on Landscape Ecology

Based on land use data of 2009 and GIS,by combining with Fragstats3.3,landscape pattern features of Panshi City have been analyzed through landscape area,number of patches,patch density,and average patch area.The results show that forest land and cultivated land take the dominance in Panshi City,the use ratio of construction land is not high and reserved land resource is not abundant.On this basis,some suggestions have been proposed in view of establishing sustainably developing land use planning and adding landscape stability.It should adjust land use structure and increase land productivity;reasonably arrange rural residential lands and enhance the treatment of discarded industrial lands;and reasonably control land scale of key towns and cities.
