基于最佳分析粒度的临川区土地利用景观格局梯度分析
Gradient Analysis of Land Use and Landscape Pattern in Linchuan District Based on Best Analytical Granularity
摘要
Abstract
The gradient changes of land use and landscape pattern in Linchuan district, Fuzhou city, Jiangxi province in 2015 were analyzed. The granularity selection is based on the granularity effect analysis and information loss assessment of the landscape. Linchuan district was divided into 21 gradient zones by using the buffer-zone gradient analysis method, and the land?scape pattern and spatial characteristics in these gradient zones were analyzed by selecting six indexes. The results showed that:( 1) The particle size of 40 m could be used for landscape gradient analysis in the study area;under this granularity, the gradient characteristics of landscape could be remained, and the landscape index did not fluctuate largely;( 2) Using the buffer-zone gra?dient analysis method could more finely analyze and reflect the characteristics of landscape pattern in the research area;( 3) Lin?chuan district could be divided into three large landscape gradient zones: the first gradient zone was gradient zone 1～4, and the urban and rural construction land dominated;the second gradient zone was gradient zone 5～10, and the main landscape was cul?tivated land; the third gradient zone was gradient zone 11～21, and the main landscape was forest land.关键词
