信宜市土地利用景观格局研究

Research on landscape pattern of land use in Xinyi City

以广东省信宜市为研究区,利用patch analyst景观格局分析软件,选取斑块数目、斑块面积、斑块密度、平均斑块大小、斑块面积标准差、斑块面积变异系数、平均斑块形状指数、面积加权平均斑块形状指数、平均斑块分维数、面积加权平均斑块分维数、破碎度、均匀度和多样性指数等指标,对信宜市土地利用景观格局进行分析。结果表明:各类景观面积分配相差较大,均匀度不高;林地景观是该地区的优势景观,可以看成是该区域的基质;园地、建设用地和耕地的破碎度大;总体景观形状较为简单,但有一定的不规则性等特点。此结果可为信宜市的发展规划提供参考依据。

The landscape pattern of land utilization in Xinyi City,Guangdong Province was analyzed by patch analyst software,selecting number of patches,total class area,patch density,mean patch size,patch size standard deviation,patch size coefficient of variation,mean shape index,area-weighted mean shape index,mean patch fractal dimension,area-weighted patch fractal dimension,fragmentation index,evenness index and diversity index as indices.The results showed that,area allocation of different landscapes had a large difference,and evenness index was not high.Forest was the dominant landscape in this region,so it could be regarded as matrix.As to garden,construction and farm land,the landscape fragmentation indices were big.Overall landscape shape was relatively simple,but it had a certain irregularity.The research results would provide reference for development planning of Xinyi City.
