基于地表覆盖数据的生态用地景观格局分析

Landscape Pattern Analysis of Ecological Land Based on Land Coverage Data

基于江苏省2015年和2018年地表覆盖数据,利用ArcGIS 10.2和Fragstats 4.2软件,对江淮生态经济区内生态用地景观格局结构特征及变化情况进行分析。结果表明:①2015年和2018年,研究区内生态用地景观格局结构特征基本相同。②2015-2018年,研究区内绿色生态用地团聚程度增强,景观格局趋向规则化;蓝色生态用地景观破碎度增强,景观格局呈现逐渐复杂化、破碎化的演变特征;灰色生态用地景观格局变化频繁且剧烈,大多是人为干扰造成。

Based on the land coverage data of Jiangsu Province in 2015 and 2018,we used ArcGIS 10.2 and Fragstats 4.2 to analyze the structural characteristics and changes of ecological land landscape pattern in the Jianghuai ecological economic zone.The results show that①in 2015 and 2018,the landscape structure characteristics of ecological land are basically the same in the study area.②From 2015 to 2018,the agglomeration degree of green ecological land has increased in the study area,and the landscape pattern tends to be regular.The landscape fragmentation of blue ecological land is enhanced,and the landscape pattern is gradually complicated and fragmented.The landscape pattern of gray ecological land changes frequently and violently,which being mostly caused by human disturbance.
