干旱区艾比湖流域典型区域景观格局脆弱性时空格局变化研究
Evaluation of the Landscape Patterns Vulnerability and Analysis of Spatial-Temporal Patterns in the Typical Region of the Ebinur Lake
摘要
Abstract
Taking the typical region in the Ebinur Lake Basin as the study area,using 1998,201 1 and 2013 3 period TM/OLI sensing image as data source,by calculating the landscape index,constructing landscape vulner-ability index and the study area is divided into low,low,high,high vulnerability areas five vulnerability level.The spatial distribution characteristics,variation pattern and spatial association pattern of landscape vulnerability in study area were analyzed by using the method of geo statistics and spatial autocorrelation model.The results showed that:1998-2013,the main types of landscape in the study area are the unused land and the cultivated land.The main feature is the significant increase in the area of cultivated land,and the other landscape area is reduced.Dur-ing the study period,the landscape vulnerability of the study area showed a significant downward trend,and the spatial variation of the grade of the study area was significant.The results show that the transition between vulnera-bility level is frequent and the conversion rate is relatively high.Fourthly,1998 -2013,landscape pattern in the study area Moran ’s I is a certain degree of positive correlation,and is closely related to the extent of a rising trend;fragile landscape of local spatial autocorrelation and significant level occurred obvious change.Correct and objective understanding and evaluation of AI Lake region’s ecological environment,conducive to the realization of the protection of the natural environment for the sustainable development of human.关键词
