摘要
为构建益阳市土地利用景观稳定性评价模型,探索其景观破碎化程度,利用益阳市2013年二类资源调查小班数据,运用增量空间自相关模型和改进型景观稳定性评价模型评价研究区域的景观稳定性。结果表明:益阳市适宜景观粒度为240m,景观适宜分析幅度为4080m。益阳市2013年景观稳定性区域差异显著,北部和西部土地利用景观斑块破碎化程度较轻,景观稳定性较高;南部景观稳定性较差;中部是益阳市社会经济发展中心,斑块破碎化程度严重,景观稳定性较差。
In order to construct an evaluation model of land use landscape stability in Yiyang City and explore the degree of landscape fragmentation. The incremental spatial autocorrelation model and improved landscape stability evaluation model were used to evaluate the landscape stability of the study area based on the data of resource survey in Yiyang City in 2013. The results show that the suitable landscape granularity of Yiyang City is 240 m, and the suitable landscape analysis range is 4 080 m. There are significant regional differences in landscape stability in Yiyang City in 2013. The fragmentation degree of land use landscape patches in the north and west of Yiyang City is relatively light, and the landscape stability is9 relatively high;the landscape stability in the south is poor;the central part is the social and economic development center of Yiyang City, the fragmentation degree of patches is serious, and the landscape stability is poor.
