An Analysis of Land Use and Landscape Pattern Evolution in Luanchuan County Based on RS and GIS
[Purposes]This paper aims to explore the landscape pattern evolution characteristics under the background of rapid urbanization in a mountainous city.[Methods]Taking Luanchuan county as the re-search area,combined with RS and GIS related technologies,and based on land use data,spatial analysis method and moving window method were used to explore,and typical landscape pattern index was selected to analyze the spatial heterogeneity of landscape pattern evolution.[Findings]The results show that:① Dur-ing the study period,the proportion of forest land in Luanchuan county was large but showed a downward trend,the area of built-up land increased significantly,the area of cultivated land and grassland was rela-tively stable,and the area of water bodies decreased.There was different degree of conversion between the types of land use;② In terms of landscape pattern,the fragmentation degree of cultivated land was higher,the connectivity and integrity of forest land were higher,the connectivity of water bodies de-creased,and the number of patches of built-up land was significantly increased;③ The spatial heteroge-neity of landscape pattern showed that the fragmentation degree of the study area increased,the shape of patches was irregularized,and the landscape types diversified.[Conclusions]The research results can provide reference basis for Luanchuan county to strengthen rational planning,promote sustainable use of re-sources and ecological environmental protection,so as to achieve sustainable development of the region.
